5 ystem description 3 Principle of operation consists of a heat pump, circulation pumps and a control system for the heat pump and additional heat. has built-in circulation pumps, making it easy to connect to the heating medium and collector circuits. The absorption of heat from the heat source (rock, ground or lake) is through a closed collector system containing water mixed with antifreeze. Ground water can also be used as a heat source. This requires an intermediate heat exchanger. The brine emits its heat to the refrigerant in the heat pump's evaporator. It then vaporises and is compressed in the compressor. The refrigerant, with its increased temperature, is led into the where it emits its energy to the heat medium circuit. The installation must be fitted with the necessary safety equipment in accordance with the applicable regulations.

8 6 ettings General 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. The heat pump is controlled by built-in sensors for flow and return 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 on 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 (see docking options 1-3). This adjustment is made automatically, however the basic settings must first be made on the boiler, see the section ettings - Default setting. Room sensors can also be used as an option to compensate for variations in room temperature, see menu 6.1 Room compensation. Default setting 9 Curve coefficient 2.1 Menu 2.1 Curve coefficient Heating curve offset The basic heating is set using menu 2.1 and with the Heating curve offset knob. If the required room temperature is not obtained, readjustment may be necessary. OTE! 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 Heating curve offset setting by one step. If the room temperature is high, reduce the Heating curve offset setting by one step.

9 ettings 7 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 scale marking corresponds to a change of about one degree in the room temperature. OTE! An increase in the room temperature may be inhibited by the radiator or floor heating thermostats, if so these must be turned up. A I II III A B I II 50.0 C Hotwatertemperature Heating curve offset

10 8 ettings etting using diagrams The heating control system on 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 Heating control system - Basic setting. The diagram is based on the dimensioned outdoor temperature in the area and the dimensioned supply temperature of the heating system. When these two values meet, the heating control's curve slope can be read.

11 ettings 9 Heat production The supply of heat to the building is controlled by the control system settings (curve slope and offset). After adjustment the correct amount of heat for the current outdoor temperature is supplied. The flow line temperature of the heat pump (heating medium flow) will hunt around the theoretically required value (the value in brackets on the display). For subnormal temperatures the control system calculates a heating deficit in the form of degree-minutes, which means that heating production is accelerated. The larger the subnormal temperature, the greater the heat production. The heat pump's control system can control the immersion heater in a maximum of 3 output steps if fitted, or an external oil-fired boiler and shunt valve. Hot water production can be complemented with Domestic hot water operation and, for example, our VPA hot water accumulator to produce domestic hot water. Additional heat only (electric boiler mode) The unit can be used solely as additional heat (electric boiler) to produce heat and hot water. This is especially useful, for example, before the collector installation is finished. Changing the Electric boiler is done in menu OTE! elect Off to deactivate only additional heat and select the required operating mode using the operating mode button. 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 (used before stable circulation has been established). The setting is made on menu Brinepump 10 days. Fixed condensing If required can be docked to an external unit with its own heating controls. then delivers heat up to a fixed temperature level. This is known as fixed condensing. To regulate the room temperature, see the instructions for the external units. tandby mode To be able to produce heat when the collector circuit is disconnected, or during servicing, the heat pump can be set to standby mode, in which case heating is produced only by the immersion heater. Hot water is not produced in standby mode. The compressor and collector system are then shutoff and only the heat medium pump and the immersion heater are active. The temperature is controlled by the thermostat (3). To select standby mode, set the switch (8) to. Electrical step 2 is connected in standby mode.

Installation is placed on a firm base, preferably a concrete floor or foundation. should be setup with its rear against an outer wall in a scullery or similar type of room to eliminate noise problems. If this is not possible, avoid placing it against a wall behind a bedroom or other room where noise may be a problem. Wherever the unit is located, any wall that backs on to a bedroom should be fitted with sound insulation. Route pipes so they are not fixed to an internal wall that backs on to a bedroom or living room. Floating condensing Heat production is usually controlled on 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 (see docking options 1-3). Fixed condensing If required can be docked to an external unit with its own heating controls. then delivers heat up to a fixed temperature level. This is called fixed condensing. ee docking option 4. To set the correct parameters for fixed condensing see Docking - option 4. The heat medium pump does not need to be changed. ee the instructions for the external units for how to regulate the room temperature. The outside temperature sensor has no function with this option, but it should be connected to prevent error messages appearing on the display. There is no need to install the sensor outside. Guideline values for collectors Type oil heat Rock heat, recommended recommended collector length active drilling depth m m m m x 250 m m x 300 m m 12 2 x x 350 m m 15 2 x x 400 m 2 x x 120 m 17 2 x x 300 m 2 x x 140 m For use with 40 x 2.4 P 6.3 PEM hose. The length of the collector hose varies depending on the rock /soil conditions and on the heating system, i.e. radiators or floor heating. Max length per collector should not exceed 400 m. 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 metres for surface soil heat. 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. OTE! Enter the selected values on page 2 in this Installation instruction. The details are important for service work.

The compressor produces up to 65* C, the rest is obtained using additional heating. * Applies to 5 kw 1-phase and 6-17 kw 3-phase 3 x 400 V. The other heat pumps has a max return temperature of approximately 50 C and an outgoing max temperature from the heat pump of approximately 60 C. ince is not fitted with shut-off valves, these must be fitted outside of the heat pump to facilitate servicing. OTE! The pipe system needs to be flushed out before the heat pump is connected so that debris cannot damage component parts. Heating medium pump The heating medium pump (VBP) runs at the same time as the brine pump (KBP) with fixed condensing (docking option 4) in auto mode. Pipe connections (collector) When dimensioning the collector, consideration must be given to the geographical location, type of rock and ground and the degree of coverage provided by 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 brine pipes in heated rooms must be insulated against condensation. The level vessel (K) must be installed as the highest point in the collector system and on the incoming pipe before the brine pump. ote 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 P 6.3) is used as a guide value when making the volume calculation. The level vessel must be marked to show the type of antifreeze used. hut-off valves should be installed as close to the heat pump as possible. Fit a particle filter to 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 extra heat exchanger. 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. You should fit either an overflow valve or remove some of the thermostats when connecting to systems with thermostats on all the radiators (coils). Ventilation recovery The installation can be supplemented with the exhaust air module FLM to provide ventilation recovery. To avoid condensation, all pipes and other cold surfaces must be isolated with diffusion-proof material. The collector circuit should be fitted with a pressure expansion vessel. If there is a level vessel, this should be replaced.

22 20 Electrical connection Centralised load control and load monitor Load monitor OTE! o function in a 1-phase installation. When many power consumers are connected in the property at the same time as the immersion heater is operating, there is a risk of the property's main fuse tripping. The heat pump is equipped with an integrated load monitor that controls the electrical steps on the immersion heater. When the phase current is so high that there is a risk of the main fuses tripping, the load monitor reduces the immersion heater output until the risk of the main fuses tripping has passed. When the general power consumption drops, the immersion heater will be connected again. A current transformer should be installed on each incoming phase conductor in to the distribution box to measure the current. The distribution box is an appropriate installation point.
