ystem description 3 Principle of operation For Home Owners consists of a heat pump, water heater, electrical module, circulation pumps and a control system.fighter 1220 is connected to the collector and heating medium circuits. The heat from the heat source (rock, soil, lake) is taken up via a closed collector system in which a mixture of water and antifreeze circulates. Groundwater can also be used as a heat source, but this requires an intervening heat exchanger. The emits its heat to the refrigerant in the heat pump s evaporator. It then vaporises and is compressed in the compressor. The refrigerant, the temperature of which has now been raised, is passed to the condenser where it gives off its energy to the heating medium circuit and, if necessary, to the water heater. After the condenser there is a built-in electrical module which cuts in if there is a high demand. Hot water circulation The heating medium side and the hot water side must be fitted with the necessary safety equipment in accordance with the applicable regulations.

For Home Owners 6 Room temperature Automatic heating control system The indoor temperature depends on several factors. unlight and heat emissions from people and household machines are normally sufficient to keep the house warm during the warmer parts of the year. When it gets colder outside, the heating system must be started. The colder it is outside, the warmer radiators and floor heating system must be. With the, this adjustment is done automatically by a control computer. Before the computer can do this, some basic settings are required. The heat pump is controlled by built-in sensors for flow and return heat brine temperatures (collector). Brine return temperatures can, if so required, be limited to a minimum (e.g. for ground water systems). Heat production is usually controlled using the floating condensing principle. This means that the temperature level needed for heating at a given outside temperature is produced on the basis of values taken from sensors for outside temperature and flow temperature. As an option, room sensors can also be used to compensate for deviations in room temperature, see menu 2.5 Compensation outer. However, the correct basic settings must be made on the boiler first, see the section Room temperature Basic setting. Basic setting A I II III A B I II 50.0 C Hotwatertemperature 1.0 13.43 Offset heating curve The basic heating is set using menu 2.1 and with the Offset heating curve knob. If you do not know the correct settings use the basic data from the map opposite. If the required room temperature is not obtained, readjustment may be necessary. NOTE! Wait one day between settings so that the temperatures have time to stabilise. Readjustment of basic settings. Cold weather conditions When the room temperature is too low, the heating curve value is increased in menu 2.1 by one increment. When the room temperature is too high, the heating curve value is decreased in menu 2.1 by one increment. Warm weather conditions If the room temperature is low, increase the offset heating curve setting by one step. If the room temperature is high, reduce the heating curve offset setting by one step. Changing the room temperature Changing the room temperature manually. If you want to temporarily or permanently lower or raise the indoor temperature relative to the previously set temperature, turn the Heating curve offset knob anticlockwise or clockwise. One to three lines approximately represents a 1 degree change in room temperature. NOTE! An increase in the room temperature may be inhibited by the radiator or floor heating thermostats, if so these must be turned up.
For Home Owners Room temperature 7 Basic values for the automatic heating control system The values stated on the map apply for the Curve slope. The first value applies for low temperature * radiator systems. Heating curve offset is set to -2. The value in brackets refers to floor heating systems** installed in concrete floor structures. When the system is installed in a timber floor structure you can use the number before the brackets, but this value must be reduced by two units. In these cases the Heating curve offset is set to -1. The map values are usually a good starting point and concern an approximate room temperature of 20 C. The values can be adjusted later if necessary. Examples of basic data selection: 1. House with low temperature* radiator system Markaryd = Area 10 (5). elect curve 10 on the display and -2 on the Increase/reduce heat knob. 2. House with floor heating** installed in a concrete floor structure Markaryd = Area 10 (5). elect curve 5 on the display and -1 on the Increase/reduce heat knob. 3. House with floor heating** installed in a timber floor structure Markaryd = Area 10 (5). elect curve 8 (10-2=8) on the display and -1 on the Increase/reduce heat knob. The lower values in the north of weden are due to the lower design outdoor temperature. 8 (4) 8 (4) 9 (4) Östersund Kiruna Gällivare Luleå kellefteå meå Örnsköldsvik undsvall Hudiksvall öderhamn 9 (4) 9 (5) Göteborg 10 (5) Halmstad Helsingborg Malmö 11 (5) Karlstad Borås Örebro Jönköping Falun Linköping Växjö Kalmar Markaryd Gävle ppsala Västerås tockholm Norrköping 9 (5) Visby Hässleholm Karlskrona imrishamn Ystad 11 (5) 12 (6) * A low temperature radiator system refers to a system where the flow temperature needs to be 55 C on the coldest day. ** Floor heating can be dimensioned very differently. Examples 2 and 3 above refer to a system where the flow temperature needs to be approximately 35-40 C resp 45-50 C on the coldest day.
For Home Owners 8 Room temperature Heating The supply of heat to the house is regulated in accordance with the chosen setting of the regulating curve (curve slope and offset). After adjustment, the correct amount of heat for the outside temperature is supplied. The heat pump s flow temperature (menu 2.0) will hover around the theoretical required value (the value in brackets on the display). For subnormal temperatures the computer calculates a deficit in the form of degree minutes, which results in the acceleration of heat production. The larger the subnormal temperature, the greater the heat production. There are four stages to heat production, one for the heat pump and three for the electrical module. The output of the electrical module as supplied is 6 kw, but it can be rewired to give 9 kw. tandby mode In order to produce heat when the collector circuit is disconnected, or during servicing, the heat pump can be set to standby mode, in which case heat is produced only by the immersion heater. Hot water is not produced in standby mode. The compressor and heat transfer system are then shutoff and only the heat medium circuit and the immersion heater are active. The temperature is controlled by the thermostat (3). To select standby mode, set the switch (8) to. In standby mode the output is 4 kw, reconnectable to 6 kw Hot water When there is a demand for hot water, the heat pump gives this priority and devotes its entire output to water heating. No room heat is produced in this mode. Maximum time for hot water charging is adjustable using menu 1.3. Heating is then produced for the remainder of the time, which is adjustable from menu 1.2, before any further hot water charging can take place. If the electrical module is connected for heat production before hot water charging, one stage remains operative during hot water operation. Hot water charging starts when the hot water sensor has fallen to the set start temperature (25 50 C), adjustable on menu 1.4. Hot water charging stops when the water temperature has reached (30 58 C), adjustable on menu 1.5. Charging is also possible when the heat pump has reached its stop level for heating mode at the same time as less than 2 C remains to the hot water start. The purpose of this is to minimise the number of starts. NOTE! The indicated hot water temperature is measured on the lower part of the water heater jacket. This means that it is not the exact temperature of the hot water. sually the outgoing hot water is hotter than the indicated temperature. For occasional higher demand for hot water, the Extra hot water function can be used to raise the temperature to about 70 C for 3 24 hours (press the Extra hot water button once). When the electrical module is connected for extra hot water the compressor stops. The value is adjustable between 50 65 C from menu 1.7. 3
General information for the installer 9 Transport and storage The must be transported and stored upright and dry. The may however be carefully laid on its back when being moved into a building. Installation is placed on a firm base, preferably a concrete floor or foundation. Install with its back to an outside wall, ideally in a room where noise does not matter. If this is not possible, avoid placing it against a wall behind a bedroom or other room where noise may be a problem. Irrespective of the placement the wall should be sound insulated. Route pipes so they are not fixed to an internal wall that backs on to a bedroom or living room.

The length of the collector hose varies depending on the rock /ground conditions and on the heating system, i.e. radiators or floor heating. Max length per collector should not exceed 400m. Where there is more than one collector, they must be connected in parallel, with a means of adjusting the flow. The hose should be buried at a depth of about 1 metre and the distance between the hoses should be at least 1 metre. For several bore holes, the distance between the holes must be at least 15m. Inspection of the installation Current regulations require the heating installation to be inspected before it is commissioned. The inspection must be carried out by a suitably qualified person and should be documented. The above applies to closed heating systems. If the heat pump is replaced, the installation must be inspected again. Electric boiler mode The unit can be used exclusively as an electric boiler, to produce heat and hot water, for example before the collector installation is complete. For this mode, the hot water temperature is preset to 50 C. ee ettings, menu 9.2.4. Brine pump The brine pump normally follows the operation of the heat pump. There is a special operating mode for continuous operation for 10 days, followed by return to normal mode (this may be used before stable circulation has been established). ee ettings, menu. 9.2.12. Electric anode (enamel) is equipped with an electric anode to protect the enamelled hot water heater. The electric anode works automatically when is switched on and is positioned behind the lower, service cover. A green LED on the transformer indicates that the electric anode is operational. When the LED is not lit the anode is not receiving power; call the installer when this can not be rectified. When the LED flashes red, contact the installer.
I II III A B I II I II A B A B 50.0 C Varmvattentemp. 1.0 For the Installer 10 Pipe connections General Pipe installation must be carried out in accordance with current norms and directives. The heat pump can only operate up to a return temperature of about 50 C and an outgoing temperature of about 60 C from the heat pump. ince the is not fitted with shut-off valves, these must be fitted outside of the heat pump to make future servicing easier. When installing FLM 30/40, pipes for the heat medium and water heater and, if necessary hot water circulation, are routed backwards. The distance between and the wall ought to be 50 mm. NOTE! The pipe work must be flushed before the heat pump is connected, so that any contaminants do not damage the component parts. Pipe connections (heating medium) Pipe connections for the heat medium side are made at the top. All required safety devices, shut-off valves (as close to the heat pump as possible), and particle filter (supplied) are fitted. When connecting to a system with thermostats on all radiators, a relief valve must be fitted, or some of the thermostats must be removed to ensure sufficient flow. Pipe connections (water heater) The water heater must be fitted with the necessary valve equipment. The heat pump should be supplemented with an electric water heater if a bubble pool or other significant consumer of hot water is installed. Pipe connections (collector) P Hot water circulation Factors to be taken into account when designing the collector layout are geographical position, type of rock/soil and cover factor of the heat pump. When installing the collector hose ensure it rises constantly towards the heat pump to avoid air pockets. If this is not possible, install high points to vent the air. All collector pipes in heated rooms must be insulated against condensation. The level vessel (NK) must be installed as the highest point in the collector system and on the incoming pipe before the brine pump. Note that condensation may drip from the level vessel. Position the vessel so that this does not harm other equipment. As the temperature of the collector system can fall below 0 C it must be protected against freezing down to -15 C. One litre of ready mixed brine per meter of collector hose (applies when using PEM-hose 40 x 2.4 PN 6.3) is used as a guide value when making the volume calculation. Details of the antifreeze used must be shown on the level vessel. The collector circuit may be connected from the left or from the right. The lower side panels are swapped over to suit the chosen connection option. The enclosed connecting pipes for the brine, are secured using the clips in the punched tabs that are folded down on the side in question. hut-off valves should be installed as close to the heat pump as possible. Fit the supplied particle filter on the incoming pipe. In the case of connection to an open groundwater system, an intermediate frost-protected circuit must be provided, because of the risk of dirt and freezing in the evaporator. This requires an additional heat exchanger. NK F ÄV EXP ÄV NK AV Brine In F Brine Out Level vessel Particle filter afety valve AV EXP F hut-off valve Expansion vessel

Then start the filling pump again. Open the valve on the main pipe between the service branches while the filling pump is still operational (to release the air between the branches). Now close the valve by the return hose. Pressurise the system (to max 3 bar) with the filling pump. Close the valve where the level vessel is fitted and stop the filler pump. Remove the filler hoses and refit the level vessel. Fill the vessel about three-quarters full with the fluid. Now shut the filling plug and open the valve under the vessel.

A high difference indicates a low brine flow. A low difference indicates a high brine flow. Particular attention should be given to the level in the collector system when initially using the heat pump. ome topping-up may be necessary. Check the Flow temperature on menu 2.0 and Return temperature on menu 2.7. The difference between these two temperatures, with floating condensing, should be 5 10 C when the heat pump heats the hot water without additional heat. A high difference could depend on a low heat medium flow. Fill in the commissioning report on page 2. et the control system to suit the needs of the building. Readjustment, heat medium side Air is initially released from the hot water and venting may be necessary. If bubbling sounds can be heard from the heat pump, the entire system requires further venting. When the system has stabilised (correct pressure and all the air removed) the heating controls can be set at the required value. Readjustment, brine side Check the fluid level in the level vessel (85). If the level has dropped, close the valve under the vessel. You can then fill through the connection at the top of the vessel. After filling, open the valve again. To raise the pressure, close the valve on the incoming main pipe when the brine pump (KBP) is running and the level vessel (NK) is open, so that water is drawn in from the vessel. Emptying the water heater The siphon principle is used to empty the water heater. This can be done either via the drain valve on the incoming cold water pipe or by inserting a hose into the cold water connection.
etting the heating controls 21 etting using diagrams Offset heating curve -2 The heating control system of the is controlled by the outside temperature. This means the flow temperature is regulated in relation to the current outdoor temperature. The relationship between the outside temperature and the flow temperature is set using the control system, also see section Room temperature Basic setting. The diagram is based on the dimensioned outdoor temperature in the area and the dimensioned flow temperature of the heating system. When these two values meet, the heating control s curve slope can be read.
