4 REMKO CMF / CMT Safety notes Carefully read the operating instruction before placing the equipment in service. It provides useful tips and information as well as hazard warnings to prevent injury or material damage!. Failure to follow the directions in this manual can result in endangerment to persons, the environment and the equipment itself and will void any claims for liability. Keep this manual and the refrigerant data sheet near the unit. The unit should be set up and installed only by qualified personnel. The set-up, connection, and operation of the unit and its components must be in accordance with the operating conditions stipulated in this manual and comply with all applicable local regulations. Mobile units must be set up securely on suitable surfaces and in an upright position. Stationary units must be permanently installed for operation. Modification of equipment and components supplied by REMKO is not permitted and can cause malfunctions. Equipment and components may not be operated in areas where there is an increased risk of damage. Observe the minimum clearances. The electrical supply is to be adapted to the requirements of the equipment. The operational safety of equipment and components is only assured if they are fully assembled and used as intended. Safety devices may not be modified or bypassed. Do not operate equipment or components with obvious defects or signs of damage. All housing parts and openings in the device, e.g. air inlets and outlets, must be free of foreign objects, fluids, or gases. The equipment and components must be kept an adequate distance from flammable, explosive, combustible, abrasive and dirty areas or atmospheres. Touching some parts of the equipment can result in burns or other injury. Installation, repair and maintenance work may be carried out only by authorised specialists. Visual inspections and cleaning can be performed by the operator as long as power is disconnected from the equipment. To preclude any danger from the equipment, take appropriate hazard-prevention measures when performing installation, repair or maintenance work or cleaning the equipment. The equipment or components are not to be exposed to any mechanical stresses, extreme levels of humidity or direct sunlight. If refrigerant has leaked from the inside module, the room must be properly ventilated before re-starting the equipment. Otherwise there is danger of suffocation. Burned-out fuses may be replaced only by those of identical construction. The units must be inspected by a service technician at least once annually In case of defects that endanger the operational safety of the unit, it must be taken out of service. Units may be mounted only at the points provided for this purpose at the factory. The devices may be attached only to load-bearing structures or walls. Regulations such as the regional building codes and the Water Ecology Act must be followed. 4

5 Disposal of packaging All products are packed for transport in environmentally friendly materials. Make a valuable contribution to reducing waste and sustaining raw materials. Only dispose of packaging at approved collection points. Only recyclable materials are used in the manufacture of the devices and components. Help protect the environment by ensuring that the devices or components (for example batteries) are not disposed in household waste, but only in accordance with local regulations and in an environmentally safe manner, e.g. using certified firms and recycling specialists or at collection points. Warranty Environmental protection and recycling Disposal of equipment and components Prerequisites for possible warranty claims are that the customer or his accepting representative has completely filled out the "warranty registration card" supplied with the unit and returned it to REMKO GmbH & Co. KG REMKO GmbH & Co. KG and placing the unit in service. The warranty conditions are listed in the "General Business and Delivery Conditions". Furthermore, only the parties to a contract can strike special agreements beyond these conditions. For this reason please contact your direct contractual partner first. Care and maintenance Regular care and maintenance serves to ensure trouble-free operation and long service-life of the heat-pump system. Care The indoor and outdoor modules must be kept free of soiling, vegetation and other deposits. The device is to be cleaned with a damp cloth. In doing so, it is to be ensured that no caustic, abrasive or solvent-based cleaning products are used. Use of powerful water jets is to be avoided. The fins on the outdoor module are to be cleaned at least once a year. Maintenance To perform the statutory seal test, it is necessary to arrange an annual maintenance contract with an appropriate specialist firm. NOTE As the refrigerant capacity exceeds 3kg, an annual seal inspection must be made of the refrigerant circuit by a firm specializing in this field. A heating system should always be serviced annually. Therefore, we recommend arranging for a service contract that includes the seal inspection. Temporary shut-down The system may not be switched off at the mains power supply even if the heating system is not used for heating purposes over an extended period (e.g. holidays)! The system is to be switched to "Stand-by" mode during temporary shut-down periods. Heating phases can be programmed for the duration of the period of absence. The previous operating mode has to be switched back on when the shut-down phase is over. Instructions for changing the mode appear in the corresponding chapter of the heat-pump manager's manual. NOTE In "Standby", the heat pump is in standby mode. Of the entire system, only the frost-protection function s activated.! CAUTION Prior to performing any work, ensure the equipment is isolated from the voltage supply and secured to prevent accidental switch-on! Note that several power feeds (circuits) are brought together in the interior module. 5

6 REMKO CMF / CMT Intended use The heat pump in general Depending on the model, the equipment and the additional fittings with which it is equipped is only intended to be used as an air-conditioner for the purpose of cooling or heating the air in an enclosed room. Different or additional use shall not be classed as intended use. The manufacturer/supplier assumes no liability for damages arising from an unintended use of the equipment. The user bears the sole risk in such cases. Using the equipment as intended also includes working in accordance with the operating manual and installation instructions and complying with the maintenance requirements. Economical and environmentallyconscious heating The burning of fossil-based energy sources in order to generate power creates severe consequences for the environment. A high percentage of fossil fuels is also problematic due to the limited resources of oil and gas and the price increases resulting from this. For this reason, many people today are thinking both economically and environmentallyconsciously in terms of heating. The application of heat pump technology enables both of these concepts to be combined. It makes use of the energy which is permanently available in the air, water and soil and converts it into usable heating energy by means of inputting electrical energy. Yet in order to generate heat equivalent to 4kWh, only 1kWh of electricity is required. The rest is made available free-of-charge by the environment. Heat source There are essentially three heat sources that heat pumps can derive energy from. air, soil and groundwater. Air heat pumps have the advantage that air as a source heat is available everywhere in unlimited quantities that can be used free of charge. A disadvantage is that the outside air is at its coldest when the heat requirement is greatest. Brine heat pumps extract energy from the soil. This is undertaken in serpentine pipe networks which are laid approx. 1m deep or placed by means of drilling. The disadvantage is the large space requirements for the serpentine pipe networks or the high cost of drilling. A long-term cooling of the soil is also a possibility. Water heat pumps require two wells in order to obtain heat from the groundwater, one supply well and one dry well. The development of this source is not possible everywhere, it is expensive and requires planning permission. Arguments for REMKO 75% free solar energy from the air * 75%* of the heat comes from the air, free of charge electrical 25% * drive energy Heating * The relationship can vary depending on outdoor temperature and operating conditions.

7 A heat pump is a device which makes use of a working medium to absorb ambient heat under low temperatures and transports this heat to a place where it can be of use for heating purposes. Heat pumps work according to the same principles as a refrigerator. The difference is that heat, the byproduct of the refrigerator, is the goal of the heat pump. The main components of the cooling circuit consist of an evaporator, a compressor, a condenser and an expansion valve. In a finned evaporator, the refrigerant evaporates both because of lower pressure and because of lower heat-source temperatures through absorption of energy from the environment. In the compressor, the refrigerant is brought to a higher pressure and temperature by the application of electrical energy. Next, the hot refrigerant gas reaches the condenser, a plate heat-exchanger. Here the hot gas condenses, transferring heat to Functional diagram heating inverter heat pump Evaporation Condensing Outdoor area the heating system. The liquefied refrigerant then expands and cools in a flow regulator, the expansion valve. Then the refrigerant flows into the evaporator once more and the cycle is complete. For control, a heat-pump manager is included which ensures the independent operation of all safety devices. The water-circulation system of the Series CMF consists of a charging pump, plate heat-exchangers, dirt traps, a manometer, fill- and drain valves, an automatic air-bleeder and flow monitor. The CMT series has, in addition, a 3-way switching valve and a buffer storage. Wall- and floor consoles, condensate pans, condensate-pan heating, a 3-way switching valve, a bypass valve and other sensors are available as accessories. Indoor area Liquefying Heat pump modes Heat pumps can work in various operating modes. Monovalent The heat pump the only source of heat for a building all year round. This mode is particularly suitable for heating plants with low supplywater temperatures and is primarily used in combination with brine/ water and water/water heat pumps. Single energy source The heat pump has an E-heater to handle peak loads. The heat pump covers the majority of the required heating power. Occasionally, when it is extremely cold outside, an electrical boosterheating system switches on as required in order to support the heat pump. Bivalent parallel The heat pump provides the entire heating energy down to a predetermined outdoor temperature. If the temperature drops below this value, a second heat source switches on to support the heat pump. There is a distinction to be made here between alternative operation with oil- or gas heat and regenerative operations with solar energy or wood-fired heating. This mode is possible for all heating systems. Decompression Heating pump outdoor unit Heat pump indoor unit 7

8 REMKO CMF / CMT Layout A precise calculation of the building's heating load according to EN is required for the design and dimensioning of a heating system. However, approximate requirements can be determined based on the year of construction and the type of building. The adjacent table shows the approximate specific heating loads for a number of building types. The required heating system output can be calculated by multiplying the area to be heated with the given values. For a precise calculation, various factors must be considered. The transmission-heat requirement, the infiltration heat-loss and an allowance for water heating comprise the total heating output which the heating system must provide. The total area of the floor surfaces, exterior wall windows, doors and roofing is required in order to determine the transmission heat requirement. In addition, information about the materials used in the building is required, as these lead to extremely varied thermal transmission coefficients (the so called K value). Also required are the room temperature and the standard outdoor temperature, that is, the lowest outdoortemperature on average that will occur during the year. The equation for calculating the transmission-heat requirement is Q=A U (tr-ta) and must be calculated separately for all roomenclosure surfaces. The infiltration heat requirement takes into consideration how often the heated room air is exchanged for cold external air. The room volume (V), the air exchange frequency (n) and the specific heat Building type Specific heating output in W/m 2 Passive energy house 10 Low-energy house built in according to energy conservation order regarding heat insulation 1995 Modern building constructed around Partially-renovated old building constructed pre-1977 Non-renovated old building constructed pre-1977 capacity (c) of the air is also required in addition to the room temperature and average low temperature. The equation is: Q=V x n x c (tr-ta) An approximate allowance for heating water - per person according to VDI 2067: 0.2 kw A residential home comprised of 150 m² living-space and a heat requirement of 100 W/m² has been selected for the example design. A total of five persons live in the house. The heat load amount to 15 kw. Adding a drinking water allowance of 0.2 kw results in a required heat output of 16 kw. Depending on the power company, an additional charge must then be made in order to factor in the service time-out period. The rating and determination of the heat pump's balance-point temperature derives Heat output [KW] Minimum performance 2. heat source 10 Heat load according to DIN EN Heat output at a supply temperature of 35 C graphically from the heat pump's temperature-specification heat-output diagram. (In the example, 35 C for a floor heating-system). Next, the heat load for the standard outdoor temperature (the lowest temperature of the year locally) and the heat threshold are marked on the graph. The outdoor-temperature-dependent heating requirement, simplified here as a straight-line relationship between heat-load and the start of the heating season, is recorded in the graph of heat-load curves. The intersection of the two straight lines with the max. heat-load curve is plotted on the X axis, where the balance-point temperature is read. (in the example, ca.-4 C) The least load of the 2nd heat source is the difference between heat load and the heat pump's maximum heat output on these days. (In the example, the capacity necessary to cover peak loads is ca. 6 kw.)

9 Characteristics of REMKO inverter heat pumps Outdoor air as a heat source An air/water heat pump absorbs energy from the outdoor air as its heat source and transmits this to the heating system. They have the following advantages over brine/water and water/water heat pump systems: Can be used everywhere Air is available everywhere in unlimited quantities. For example, no wells are required. No excavation required No large areas are required for soil collectors. Economical Expensive drilling is not required. The heat pump's condenser is equipped with a requirementdependent speed control system. The power control on conventional heat pumps provides only two states, either ON (full output) or OFF (no output). The heat pump turns on below a specified temperature and turns off when this temperature is reached. This kind of heat regulation is very inefficient. Heat regulation in the REMKO inverter heat pump is modulated to the actual need. The electronics system has an integrated frequency-converter which serves to modify the condenser speed and the speed of the blower as required. The condenser works at a higher speed when under full load than under partial load. The lower speeds ensure a longer operational lifetime for the components, improved coefficient of performance and lower noise. Lower speeds also result in lower energy consumption (electricity) and longer service life. I.e.: inverter heat-pumps will run practically throughout the heating season. In all, the highest efficiency possible. Excellent value for money and simple installation Particularly suitable for lowenergy houses with low inlet temperatures Ideal for bivalent operation, in order to save energy Temperature Modern inverter technology Split AC unit The REMKO inverter heat pump is a so called split AC unit. This means that it consists of an outdoor unit and an indoor unit, both of which are connected via refrigerantcarrying copper pipes. Thus there are no water-carrying pipes laid from the indoors to outdoors which need to be made frost proof. The outdoor unit contains only the condenser, the evaporator and the expansion valve. This means that the outdoor unit is considerably smaller. The indoor module contains the system's condenser and the connections for the heating network. 1/3 NOTE Conventional Inverter Minimal temperature fluctuations mean energy savings When it is switched on, the inverter only requires one-third of the time of conventional systems Thanks to innovative inverter technology, this heat pump will almost always operate by adapting its heat output to the actual requirements of the heating season, and will in fact turn itself off when heat is no longer needed. The same applies in the opposite direction with cooling. Time 9

10 REMKO CMF / CMT Defrost by circulation reversal Cooling mode At temperatures below about +5 C, humidity freezes in the evaporator (outdoor module) and an ice layer can form which reduces heat transfer from the air to the refrigerant and to the air stream. This layer of ice must be removed. A four-way valve serves to reverse the refrigerant circuit, so that the hot gas from the compressor flows through the original evaporator and the ice that has formed there can melt. The defrost process is not initiated after a predetermined time; rather it is carried out as required in order to save energy. Because of circuit reversal, cooling is also possible. In cooling mode, the components of the refrigeration circuit are used to produce cold water with which heat can be extracted from a building. This can be accomplished with dynamic cooling or passive cooling. Under dynamic cooling the refrigerating capacity is actively transferred to the indoor air. This is undertaken by means of water-based fan convectors. In doing so, it is desirable that the inlet temperatures are under the dewpoint, in order to transfer a higher refrigerating capacity and to dehumidify the indoor air. Passive cooling refers to the absorption of heat via cooled floors, walls or ceiling surfaces. In doing so, water-carrying pipes make the structural sections into thermically effective heat exchangers. In order to achieve this, the refrigerant temperature has to lie above the dew point, in order to avoid the formation of condensation. Dewpoint monitoring is required for this purpose. We recommend dynamic cooling with fan convectors, in order to achieve increased thermal performance and in order to dehumidify the air on muggy summer days. The advantage here is that dewpoint monitoring is not required. The comfort zone in the illustration below shows which values for temperature and humidity are considered comfortable for people. This range should ideally be met when heating or air-conditioning buildings. Relative humidity in % uncomfortably humid comfortable uncomfortably dry still comfortable Room air temperature in o C 10

11 Versions CMF Series We offer two different indoor-unit designs. The wall-mounted CMF Series is equipped with a circulation pump and a safety module on the water side. Furthermore, an electrical booster heater can be incorporated as an option. The CMF Series was constructed for the addition of several heat sources (bivalent installations or systems with solar-heating equipment). External buffer storage is always required, its size depending on the type and the power of the second heat source. On the one hand, the buffer storage prevents short run-times for the heat pump and on the other hand, that sufficient defrosting energy is available.

12 REMKO CMF / CMT CMT Series In addition, the indoor module of the CMT series is fitted with a hotwater buffer storage. An electric booster heater with a max. output of 9 kw is standard. The hot-water buffer-storage has a capacity of 150 litres and is integrated as a hydraulic switch. As a result, the CMT Series is the ideal equipment when the heat pump is intended as the sole heat source (single energy-source operation).

13 Installation instructions The indoor and outdoor modules have to be connected with refrigerant lines of dimensions 3 / 8 " (ca. 16 mm) and 5 / 8 " (ca. 10 mm). A four-wire control cable has to be laid between the two modules. Both the indoor and outdoor modules require a separate power supply.

15 General Information These instructions are to be observed when installing the entire system. The device should be delivered as near as possible to the site of installation in its original packaging in order to avoid transport damage. The device is to be checked for visible signs of transport damage. Possible defects must be reported immediately to contract partners and the forwarding agent. Suitable sites for installation are to be selected with regard to machinery noise and the set-up process. The shut-off valves for the refrigerant lines may only be opened immediately before commissioning of the system. The exterior components are pre-filled with refrigerant up to a distance of 30 meters from the interior component. If the basic length of the refrigerant line exceeds 30 metres, add refrigerant. Establish all electrical connections in accordance with the relevant DIN and VDE standards. The electrical power cables must be fastened to the electrical terminals in the proper manner. Otherwise there is a risk of fire. See that neither refrigerant or pipes that carry water pass through living- or sleeping areas. Wall breakthroughs A wall opening of at least 70 mm diameter and 10 mm slope from the inside to the outside must be created. To prevent damage, the interior of the wall opening should be padded or, for example, lined with PVC pipe (see figure). After installation has been completed, use a suitable sealing compound to close off the wall breakthrough under observation of fire protection regulations (responsibility of customer). Liquid line Supply Control cable Hot gas line! CAUTION Open refrigerant pipes must be protected against the introduction of moisture by means of suitable caps or adhesive strips Refrigerant pipes may not be kinked or compressed. Refrigerant pipes may only be cut to length with a suitable pipe cutter (use no hacksaws or the like).! CAUTION The installation of refrigerant equipment may be undertaken only by trained specialist personnel.! CAUTION All electrical installation work is to be performed by speciality companies. 15

16 REMKO CMF / CMT Installation or setting up the indoor module Indoor module CMF Series The wall bracket is to be attached to the wall with the fasteners supplied and the indoor module hooked onto it. The wall must possess sufficient load-bearing capacity for the weight of the indoor module. Ensure that the wall bracket is installed level. The indoor module can be aligned precisely by means of the adjustment screws on the back of the housing. The indoor module is to be mounted in such a way that all of the sides have sufficient space for purposes of installation and maintenance. It is equally important that there is sufficient space above the device for installing the safety assembly. Indoor module CMT Series The indoor module must be installed on a firm, level surface. The surface must possess sufficient load-bearing capacity for the weight of the indoor module. The height-adjustable feet can be used to level the indoor module precisely. The indoor module is to be mounted in such a way that all of the sides have sufficient space for purposes of installation and maintenance. It is equally important that there is sufficient space above the device for installing the pipes and the safety assembly. Floor mounting CMT 120 / 160 NOTE Only fasteners suitable for the given application may be used. Wall mounting CMF 120 /

17 Outdoor-module installation location The device may be attached only to a load-bearing structure or wall. Ensure that the outdoor module is installed only vertically. The installation site should be well ventilated. To minimise noise, install floor consoles with vibration dampers and a considerable distance from acoustically-reflective walls to minimise noise. The minimum clearances specified on the next page should be maintained when carrying out the installation. These minimum distances serve to ensure unrestricted air intake and exhaust. Additionally, there must be adequate space available for installation, maintenance and repair. If the outdoor module is erected in an area of strong winds, then the device must be protected against them. The snow line is to be observed during installation (see figures). The outdoor module must always be installed on vibration dampers. Vibration dampers prevent the transmission of vibrations through the floor or walls. A heated, condensate catchpan ensures that condensation from the pan can drain off. Ensure that the condensate is prevented from freezing so that it can drain off (gravel, drainage). The Water Ecology Act is to be observed. If there is insufficient space under the device for the refrigerant lines, then the precut recesses can be removed from the lower enclosure-panel and the pipes guided through these openings. During installation, add about 20 cm to the expected snow depth to guarantee unimpeded intake and exhaust of outdoor air year round. The installation site of the outdoor module should be agreed together with the operator primarily so that operating noise is minimised and not in terms of short routes. Thanks to the splitdesign technology there are a great deal of different installation options with almost identical efficiency available. Wind Snow + 20 cm NOTE The site for the outdoor module must be selected so that machinery noise that occurs disturbs neither the residents nor the facility operator. Observe the TAnoise specifications as well as the table containing the drawings relating to sound pressure levels on page 53!

19 Condensate- and meltwater drainage Special attention must be directed to the topic of condensate- and melt-water drainage. In every case, steps must be taken to keep, for example paths, entrances and the like free of water and frost. With help from our condensate drain-pan, any incidental condensation under the outdoor module is first collected there and is then directed to seep away either through a pipe buried on site or into the sewage system. Please find additional information on this topic in our manual "Condensate Drain Pan".

20 REMKO CMF / CMT Hydraulic connection We recommend installing a buffer storage unit as a hydraulic switch for hydraulically isolation of the heating circuit. Make a pipe-network calculation before installing the heat pump. After installing the heat pump, it is necessary to perform a hydraulic balancing of the heating circuit. Protect floor heating systems against excessively high inlet temperatures. Do not reduce pipe diameters for the supply and return connections to the heat pump before connecting a buffer storage-unit. Plan for air bleed valves and drain-off taps at appropriate places. Flush the the system's entire pipe network before connecting the heat pump. One or, where necessary, several expansion tanks must be designed for the entire hydraulic system. The system pressure of the entire pipe network is to be matched to the hydraulic system and must be checked when the heat pump is turned off. Also update the staticpressure form supplied with the heat pump. 20 NOTE A separate interpretation of nominal flow rate must be made for every system (see attachment: Technical Data). As delivered, the safety assembly consists of a manometer, air bleeder and safety valve. It is to be mounted to the pipe connection provided on the indoor module. Manometer The heat pump requires a constant, minimum standingwater volume of 100 litres to guarantee power for defrosting and to assure a minimum running time. Buffer storage unit The stop cocks supplied are to be positioned directly at the connections for the heat pump for the heater circuit inlet and return lines. The shut-off valves each contain a thermometer.! CAUTION Automatic bleeder Safety valve Indoor unit Turning the thermometer heads serves to close or open the stop valves! The dial be brought into the desired position. Install the dirt traps delivered with the unit outside the heat pump in the return line. Ensure that the dirt trap remains accessible for inspection. Be sure to position one gate valve upstream and another downstream of the dirt traps. This ensures that the dirt traps can be checked at any time without loosing water. The dirt traps must be checked during every service of the system. Additionally, a hand-operated bleeder is installed on the heat pump for additional bleeding. All visible metallic surfaces must be additionally insulated. Cooling mode via the heating circuit requires a completely vapour diffusion tight insulation along the entire length of the pipework. All outgoing heating circuits, including the connections for water heating, are to be secured against circulating water by means of check valves. Before being placed in service, the system must be thoroughly flushed. Conduct a seal test and perform a thorough bleeding of both the indoor module and the entire system - repeatedly, if necessary. NOTE Actual schemas for hydraulic integration can be found on the internet at

21 Corrosion protection Oxygen always plays a role if metal materials in a heating system corrode. ph values and the salt content also play a major role. The challenge: A licenced plumber who would like to be able to guarantee his customers a hot water heating system not at risk of corrosion from oxygen - without the use of chemicals - must pay attention to the following: Correct system design by the heating contractor/planner. Subject to the installed materials: filling the heating system with demineralised softwater or fully deionised water, checking the ph value after 8 to 12 weeks. See the following table for the requirements in accordance with VDI 2035 Part 1 with regard to total hardness. Overall output in kw Total hardness [ dh] subject to the specific system volume <20 l/kw >20 l/kw and <50 l/kw >50 l/kw to 50 kw <16.8 dh <11.2 dh <0.11 dh The following table provides the allowed oxygen content in connection with the salt content. Reference values for the hot water in accordance with VDI 2035 Part 2 Electrical conductivity at 25 C low-salt saline μs/cm < Oxygen content mg/l < 0,1 < 0,02 ph value at 25 C 8,2-10,0*) *) For aluminium and aluminium alloys the ph value range is limited: the ph value at 25 C is (max. 9.0 for aluminium alloys) Water treatment with chemicals is not necessary Adding chemicals to treat water should only be done as an exception. VDI 2035 Part 2 requires explicitly under Point that all water treatment be explained and documented in the system log book. This has reasons: The improper use of chemicals often leads to the failure of elastomer materials, to blockages and deposits because of sludge formation, to defective floating seals in pumps and finally to the formation of biofilm which can cause microbial influenced corrosion or significantly impair heat transfer. Incidentally: For low-salt water and the correct ph value, even oxygen concentrations up to 0.5 mg/l can be tolerated for short periods. 21

22 REMKO CMF / CMT Electrical connection It is necessary to lay a power-supply cable both to the outdoor module and, separately, to the indoor module. Power to the indoor module may not be disconnected by the power company. (Frost protection) All indoor- and outdoor modules of the CMF / CMT 120 Series require a single-phase power supply at 230 V. / 50 Hz. The outdoor module of the CMF / CMT 160 Series can be supplied with three-phase voltage at 400 V / 50Hz. The electrical connection between outdoor- and indoor modules is made using fourwire control cable. Where applicable, a separate power supply shall be provided to the indoor module for electric booster heating. The heat-pump manager needs to know whether a powercompany release- or off-period is in effect. An electricallyisolated switch must be installed for this purpose. (An open switch signifies power available, an open switch, off-time.) A connection schematic along with corresponding circuit diagrams can be found in the appendix of this manual. Special rates for heat pumps may be offered by the powercompany company (PSC).

23 Electrical connection - indoor module The following instructions describe the electrical connection of the CMF and CMT Series indoor module. Shown here is the connection for the CMF Series. Differences for connecting the CMT Series are presented as they arise. 1. Fold down or remove the lower housing-cover (Fig. 1). 2. Loosen the two screws that secure the front of the housing and move it upward (Fig. 2). 3. Loosen the two screws that secure the control-box cover, and lower it. Now, the cover can be removed (Fig. 3) and the control box be lowered for inserting the electric cables. (Fig. 4). 1 Remove the lower housing-cover 4. Thread the power cable - as well as the control cable between the indoor- and outdoor modules and the cables for external devices and sensors - though the cable openings into the indoor module (Fig. 5). Note that the cable openings in the CMT series are located above rather than below. 3 Loosen the screws 4 Lower the control box NOTE The number of lines and the sensors is dependent on the configuration of the heating system and the components. NOTE Attach cables in accordance with the connection schematic and/or the circuit diagram in the control box.! CAUTION Ensure correct polarity when connecting the electrical leads, especially the control cable.! CAUTION Make sure to use enough cable when installing the indoor module so that the control box can be fully lowered for future maintenance.! CAUTION At the site, avoid adding cable inlets. 2 Loosen the screws 5 Insert the cables Cable passage 23

25 Temperature sensors The number of sensors required can vary with the type of system. In the indoor module (F11), the collector sensor, the return sensor (F17) and the sensor for the liquid line (refrigeration circuit) are already installed and connected. Observe the pertinent notes for the sensor position found in the hydraulic schematic. The standard model includes an external sensor, a submersible sensor (intended for use as a custom hot-water sensor), as well as a contact sensor. When connecting solar panels, the PT-1000 sensor must be used to measuring the collector temperature! (F14) All other sensors must be NTC-sensors with a reference resistance of 5 kilo Ohms. All sensors are to be connected to the indoor-module switching-cabinet according to the terminal-assignment diagram. Contact sensor Contact sensors can be mounted on the pipes, to measure the heating-circuit temperatures, for example. The contact sensor is fastened to a pipe with the trapezoidal brackets and retaining strap provided. Clean the mounting point on the pipe. Subsequently a thermal compound (A) is applied and the sensor is fixed in position. NOTE If the sensor cables are too short, they can be extended up to a maximum of 100m with wire having a cross-section of 1.5 mm². External sensor The connection of an outdoor sensor is always required for the heat pump manager. Mount the outdoor sensor pointing skyward, in a northeasterly direction, about 2.5 metres above the ground. It may not be subjected to direct sunlight and is to be protected against excessive wind. Installation above windows or air ducts is to be avoided. In order to carry out the installation, remove the cover and secure the sensor with the screws provided. A cable with wire cross-sections of 0.5 mm² is recommended for connecting the sensor. 25

26 REMKO CMF / CMT Connection of refrigerant lines The outdoor- and the indoor modules are connected with two copper pipes of refrigerator quality having the dimensions and (REMKO special accessory). Observe the permitted bending radius for the refrigerant pipes during installation in order to prevent kinks. Never bend a pipe twice in the same place in order to prevent embrittlement or crack formation. Assure suitable fastening and insulation when laying the refrigerant pipes. The copper pipes are to be flared to make the connections to the modules. In doing so, check that the flare has the correct shape and suitable union nuts. (Figs. 6-8). 6 Deburring the refrigerant line Deburrer Refrigerant line 7 Flanging the refrigerant line Flanging tool 8 Correct flange shape Copper piping Outside diameter Connection to the unit Flare dimensions ø A 3/8 or 9.52 mm mm 5/8 or mm mm Remove the cover panel from the outdoor module. It may be necessary to remove the precut bushings. Take off the factory-fitted protective caps. You can use the union nuts for additional mounting. Make sure to slide the union nuts onto the pipe before it is flared. Make connections to the device by hand initially, in order to ensure a good fit. Later, tighten the joints with two open-end wrenches Use one wrench to resist the rotation of the other (Fig. 9). 9 Tighten fittings Tighten 1st Spanner Counter 2nd Spanner Tightening torque : Nm : Nm The installed refrigerant pipes, including the flare connections, must be provided with suitable insulation. Special measures need not be taken for the return of the compressor oil. NOTE Outdoor modules may be delivered with nuts suitable for joining flanges. NOTE Use only tools which are approved for use in an HVAC environment. (z. B.: bending pliers, pipe/tubing cutters, deburrers and flaring tools). Do not cut refrigerant pipes with a saw.! CAUTION All work must be carried out in a way that prevents dirt, particles, water etc. from entering, refrigerant lines! 26

27 Placing the refrigeration system in service Monitoring for leaks Connect the manometer to at least one Schrader valve on the shut-off valves of the outdoor module. The leak test must to be undertaken with dried nitrogen at a test pressure of 40 bar for a period of 30 minutes. Pipeline joints and connectors must be checked with a suitable leak detector and any leaks rectified. Pumping down to vacuum Excess pressure must be removed from the refrigerant pipes. The vacuum pump should show a final partial pressure of no more than 10 mbar in order to remove all foreign gasses and moisture from the pipelines. The time required to generate the vacuum depends on the length of the refrigerant pipes. A test time of at least 60 Minutes is recommended. When the foreign gasses have been completely removed from the system, the valves on the manometer station are closed. Add refrigerant The outdoor module is prefilled with refrigerant sufficient for a length of ordinary pipe up to 30 metres. If the length of any pipe exceeds 30 metres, a supplementary refrigerant charge of 600g per 10 metres of pipe (single length) is required.! CAUTION Only refrigerant in a liquid state may be used to fill the cooling circuit. Connecting the cold circuit After the previously described work and tests, the shut-off valve must be completely opened counter-clockwise with the appropriate hex key. Doing so connects the outdoor module cryogenically with the outdoor module. Only at this point is the heat-pump system cryogenically functional. Next, screw on the cover caps and check the seals of the entire shut-off valve for tightness. Now come the performance tests and supplementary isolation of all connections to prevent condensation shorts.! CAUTION A vacuum of at least 20 mbar must be produced!! CAUTION The connection of refrigerant pipes and the handling of refrigerant may be carried out only by authorised specialists (competence category I). 27

28 REMKO CMF / CMT Control panel Green indicator light Outdoor module is activated Red indicator light Outdoor-module failure Heat pump manager (control-and-display unit) Mode switch Position I: Normal operation This switch turns on the system. The heat pump and a possible 2nd heat source (6 kw E-heater or boiler), load- and weather-dependent, are turned on and off - as well as regulated - automatically. Position 0: OFF Position II: Emergency-heat operation This switch directly turns on all circulation pumps and the 2. heat source (9 kw E-heater or boiler), bypassing the heat-pump manager. Use this position only if a serious malfunction of the heat pump occurs (e.g.: a fault in the outdoor module or in the heat-pump manager). This function might also be helpful if heat is ever required and the outdoor module has not yet been installed or or placed in service.! CAUTION Make sure that no weather-driven control occurs during emergency-heat operation. Therefore, limit the inlet temperature at the controller for the electric booster heater or at the external controller for the boiler to a maximum temperature matched to the boiler. (e.g.: 55 C for floor heating-systems)! NOTE When the heat pump is switched off (position 0 on the function switch), the heating system is switched off. There is no frost protection function. 28

29 Notes for commissioning The Multitalent heat pump manager serves to operate and control the entire plant. The heat pump manager itself is operated by the control unit. The control console is connected to the basic device and is located behind the flap on the indoor module. C! CAUTION After a power failure etc.,the previously programmed configuration can be accepted immediately by pressing the F-button next to End. This also happens automatically after a delay of 10 minutes. System 1 is pre-installed at the factory. After a reset of the heat-pump manager, the parameters for System 1 are loaded. An intensive visual inspection is to be carried out before the actual commissioning. Switch on the electrical supply. the parameters that go with it (see the hydraulic schematic in the heat-pump manager handbook). The system has to be matched to the customer's personal values (e.g. inlet temperature). The brief instructions supplied give an overview of how to set the most important values. After configuration, the system is to be run-in and the measured values are to be recorded in the commissioning report. A B The following screen appears on the Multitalent display.

66 REMKO CMF / CMT General terms Defrost At outdoor temperatures below 5 C it is possible that ice may form on the evaporators of air/water heat pumps. The removal of this ice is referred to as defrosting and is undertaken by supplying heat, either regularly or as requirements dictate. Air/water heat pumps with circuit reversal are distinguished by their requirements-based, quick and energy-efficient defrosting system. Bivalent mode The heat pump provides the entire heating energy down to a predetermined outdoor temperature (e.g. 0 C). If the temperature drops below this value, the heat pump switches off and the secondary heating appliance takes over the heating, e.g. a heating boiler. Seal inspection System operators are obliged to ensure the prevention of refrigerant leakage in accordance with the directive on substances that deplete the ozone layer (EC 2037/2000) and the Regulation on Certain Fluorinated Greenhouse Gases (EC 842/2006). In addition, a minimum of one annual service and inspection must be carried out, as well as a sealing test for refrigerating plants with a refrigerant filling weight over 3 kg. Energy supply company switching Certain energy supply companies offer special tariffs for the operation of heat pumps. Expansion valve Heat pump component for lowering the condensing pressure on the vapour tension. In addition, the expansion valve regulates the quantity of injected refrigerant in relation to the evaporator load. Support The German Reconstruction Loan Corporation supports ecologically-sound construction and modernisation of domestic buildings for private individuals. This includes heat pumps which can be supported in the form of loans. The German Federal Office of Economics and Export Control (BAFA) subsidises the installation of effective heat pumps (please refer to: und Limit temperature / bivalence point Outdoor temperature where the secondary heating appliance cuts in under bivalent operation. Heating output Flow of heat emitted from the liquefier to the environment. The heating output is the sum of the electrical power consumed by the condenser and the heat flux obtained from the environment. Inverter power regulator which serves to match the speed of the compressor motor and the speed of the evaporator fans to the heating requirement. Seasonal performance factor The seasonal performance factor relates to the ratio of heat content delivered by the heat pump system to the supplied electrical energy in one year. It may not be compared to the performance number. The seasonal performance factor expresses the reciprocal of the annual power input factor Annual power input factor The annual power input factor indicates the power input (e.g. electrical energy) required in order to achieve a certain benefit (e.g. heating energy). The annual power input factor includes the energy required for auxiliary drives. Calculation of the annual power input factor is undertaken according to VDI Directive Refrigerating capacity Heat flux extracted from the environment by the evaporator (air, water or soil). Refrigerant The working medium used in a refrigerant plant, e.g. heat pump, is referred to as the refrigerant. The refrigerant is a liquid which is used for thermal transfer in a refrigeration plant and which is able to absorb heat by changing its state at low temperatures and low pressures. A further change of state at higher temperatures and higher pressure serves to dissipate this heat. Compressor (condenser) Unit designed for the mechanical conveyance and compression of gasses. Compression serves to significantly increase the pressure and temperature of the medium. 66

67 Coefficient of performance The current ratio of thermal output produced by the heat pump to the consumed electrical power is referred to as the coefficient of performance, as measured under standardised boundary conditions according to EN 255 / EN A coefficient of performance of 4 means that a usable thermal output amounting to 4-times the electrical power consumption is available. Single energy-source mode The heat pump covers a large proportion of the required thermal output. On a few days per year an electrical heating coil supplements the heat pump under extremely low outdoor temperatures. Dimensioning of the heat pump for air/water heat pumps is generally based on a limit temperature (also known as balance point) of approx. -5 C. Monovalent mode In this mode, the heat pump is the sole heating appliance in the building all year round. Monovalent mode is primarily used in combination with brine/water and water/water heat pumps. Storage tank The installation of a hotwater storage tank is generally recommended in order to extend the running time of the heat pump under low heat requirements. A storage tank is required for air/ water heat pumps in order to bridge off-periods. Noise Noise is transmitted in media such as air or water. Essentially there are two types of noise, airborne sound and solid-borne sound. Airborne sound is transmitted entirely via the air. Solid-borne sound is transmitted in solid materials or liquids and is only partially radiated as airborne sound. The audible range of sound lies between 20 and 20,000 Hz. Sound pressure level The sound pressure level is a comparable characteristic quantity for the radiated acoustic output of a machine, for example, a heat pump. The noise emission level at certain distances and acoustic environments can be measured. The standard is based on a sound pressure level given as a nominal noise level. Split AC unit Design where one part of the device is positioned outdoors and the other inside the building. Both units are connected to each other by a refrigerant pipe. Evaporator Heat exchanger on a refrigerant plant which uses the evaporation of a working medium in order to extract heat from its environment at low temperatures (e.g. the outdoor air). Condenser Heat exchanger on a refrigerant plant which liquefies a working medium in order to transmit heat to its environment (e.g. the heating system). Regulations and guidelines The erection, installation and commissioning of heat pumps has to be undertaken by qualified specialist engineers. In doing so, various standards and directives are to be observed. Heat requirement assessment A precise dimensioning of the system must be carried out for heat pump systems in order to maximise efficiency. Calculation of the heat requirement is undertaken according to national standards. However, approximate requirements can be determined based on the W/m² tables multiplied by living space to be heated. The result of this is the overall heat requirement, which includes the transmission heat requirement and the infiltration heat loss. Heat pump system A heat pump system consists of a heat pump and a heat source system. For brine and water/water heat pumps, the heat source system must be made available separately. Heat source Medium from which the heat pump derives heat, in other words, soil, air and water. Heat carrier Liquid or gas medium (e.g. water, brine or air), in which heat is transported. 67
