5 For Home Owners System description System description Principle of operation consists of a heat pump module and a control system with a display for operating the heat pump, soft start relay (8-12 kw) and additional heating. 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 condenser where it emits its energy to the heating medium circuit. In the event of cooling, the direction of flow changes in the refrigerant system. Even the external systems (brine and heating medium) change direction by the external pumps starting for opposite circulation. The heat energy is now emitted to the heat source (via the collector) which is recharged.

8 For Home Owners Control Control General The indoor temperature depends on several factors. Sunlight 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 hot, can be used to cool. When it gets colder outside, the heating system must be started. In this adjustment is done automatically by a control system. Before the system can do this, some basic settings are required. 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). The room sensor is used to compensate the deviation in room temperature. Setting heat/cooling Setting takes place by programming the Curve slope, see the section Available information and on-display settings, page 7, and by setting Offset heating curve / Cooling curve offset, page 21, using the Increase/reduce room temperature knob on the panel. 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. Readjusting the setting Cold weather conditions If the room temperature is too low, increase the value for the heating curve by one step. If the room temperature is too high, reduce the value for the heating curve by one step. Warm weather conditions If the room temperature is too low, turn the Increase/reduce room temperature knob one step clockwise. If the room temperature is too high, turn the Increase/reduce room temperature knob one step anticlockwise. Cooling with room sensors If RG-2 is installed and Cooling in menu 19 is "On", the cooling function activates at 1 C in excess of the set temperature (selectable: 1-9 C above set temperature). Cooling then occurs with the min.flow as the set point. The cooling function is deactivated when the room temperature drops by half the selected excess temperature. After the ended period for cooling, heating cannot start until 3 hours have passed and vice versa. 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 heat pump flow temperature (WWout) will hover around the theoretical required value (the value in brackets on the display). For subnormal temperatures the system calculates a deficit in the form of degree minutes, this results in the acceleration of heat production. The larger the subnormal temperature, the greater the heat production. The heat pump s control system can control any installed external additional heaters in a power stage. Hot water production When supplementing with the accessory Hot water control and, for example, our hot water accumulator VPA, FIGHTER 1127 can be used for hot water production. Brine pump The brine pump normally follows the operation of the heat pump. There is a special operating mode for continuous operation for 1 days, followed by return to normal mode (used before stable circulation has been established). Circulation pumps, cooling During cooling, the internal circulation pumps do not run and the external circulation pumps start. Changing the room temperature Changing the room temperature manually If you want to temporarily or permanently increase or lower the indoor temperature in relation to the previous heat setting, turn the Increase/reduce room temperature knob clockwise or anticlockwise. One line approximately represents a 1 degree change in room temperature. Note! An increase in the room temperature can be slowed by ant thermostat valves in the system, which must then be opened. 6

9 For Home Owners Control Available information and on-display settings has a two-line LCD display. The heat pump can be set via this display and its associated buttons. Channel selection The Channel button lets you browse through the following display modes to find the information you require. Values within brackets are also described within brackets. If a value is programmable, this is denoted by a [P] (Programmable) in front of the value. If the next value cannot be changed, you can access the next menu by pressing Channel. Setting The first step when changing a value is to press the Increase button once. A cursor (line) then appears under the value.

12 For the Installer General points for the installation engineer General points for the installation engineer Transport and storage should be transported and stored vertically in a dry place. Assembly is placed on a firm base, preferably on 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 Control of the heating/cooling production is performed based on the floating condensing principle, i.e. the temperature level needed for heating at a specific outdoor temperature is produced guided by collected values from the outside and flow sensors. The room sensor is used to compensate the deviation in room temperature. Guideline values for collectors* Recommended collector length must be adjusted according to local conditions. 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 4 m. Where there is more than one collector, they must be connected in parallel, with a means of adjusting the flow. For surface soil heat, 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 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. * For use with 4 x 2.4 PN 6.3 PEM hose. 1

13 For the Installer Control (also with accessories) Control (also with accessories) General Hold the Channel button down for about 7 seconds to access the following menus. Then press Channel again until you reach the desired display mode. To change the value of a displayed variable, first press the Increase button once. A cursor will appear under the value. The value can now be changed by pressing the Increase or Reduce buttons. Pressing the Channel button again moves the cursor to the value below, which in some cases can now be changed. Control of the electrical output for best comfort is managed by the system. It calculates the flow temperature deficit in the form of degree-minutes. If, for example, the flow temperature has been 3 degrees lower than the calculated flow temperature for 6 minutes, 3 x 6 = 18 degree minutes is registered by the control system. Using the standard setting the number of degree minutes should amount to 36 (6 + 3) before the external additional heat is connected. After which the following steps are connected with a further 1 degree minutes difference. The output step remains actuated until the degree minute deficit for each step has been compensated, which means that the flow temperature must be as many degree minutes above the calculated flow level as it was previously under. This way the average flow temperature calculated by the system is obtained. Settings 1a GM (Degree-min) GM [P] Current value for number of degree-minutes. For example, this value can be changed to accelerate the start of heating/cooling production. Setting range: b HP- min 6 Add- min 3 This menu is a submenu to menu 1 and is activated by using the Increase button, set the cursor under the value for GM and press Channel.

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 expansion tank (EXP) is located on the incoming pipe before the brine pump. As the temperature of brine system can fall below 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 4 x 2.4 PN 6.3) is used as a guide value when making the volume calculation. The expansion tank must be marked to show the 3 % type Etylenglykol of antifreeze used. Shut-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.

18 For the Installer Electrical connections Electrical connections Removing the covers Electrical installation NOTE Electrical installation and service must be carried out under the supervision of a qualified electrician. Electrical installation and wiring must be carried out in accordance with the stipulations in force. Terminal block, incoming electricity (9) Cable duct for supply Cable duct for sensors Supply cables to the heat pump are placed in the cable duct on the left of the unit. Cables for external sensors must enter on the right-hand side. Cables may exit via the top or the rear. 16

19 For the Installer Electrical connections Connection A heat pump must not be connected without the permission of the electricity supplier and must be connected under the supervision of a qualified electrician. If a miniature circuit breaker is used this should have motor characteristic D (compressor operation). For MCB size see Technical Specifications. When the building is equipped with an earth-fault breaker the heat pump should be equipped with a separate one. does not include an omnipolar circuit breaker on the incoming power supply. Thus, the installation must be preceded by a safety switch with at least a 3mm gap. If an insulation test is to be carried out in the building, disconnect the heat pump. Connect the heat pump to 23 V 1-phase, neutral + ground via a distribution board with fuses. Connection of room temperature sensor RG-2 It is important that no other heat source, for example, lamps, TV or other heat-emitting objects interfere with the room sensor (155). Curtains should not cover the sensor. Install in a neutral position where the set temperature is required. A suitable place is on a free inner wall in a hall approx. 1.5 m above the floor. However, the sensor must not be prevented from measuring the correct indoor temperature, for example, by placing in a niche, between shelves, behind a curtain, above or close to a heat source or the like. Also consider any draughts from exterior doors. Neither must the unit be affected by solar incident radiation. The conduit should be sealed next to the sensor to prevent a draught in the pipe, which could affect the sensor. The sensor is connected to terminals "1", "4", "5" and "6" on the relay card s -E29 (29) terminal block -X3 (3) (see image). Connection to 4 wire cable, for example, 4 x.25 LiYY (<1 m). The sensor cable must not be routed parallel with power cable. Connecting the outside sensor The outside sensor (15) must be installed in a shaded location on a wall facing north or north-west, where it will not be affected by any morning sun. The sensor is connected by two wires to terminals 7 and 8 of terminal block X3 (3) on the relay card E29 (29). The minimum cable cross section is.4 mm2 up to 5 metres. Suitable cable types are EKKX or LiYY. If the outside sensor cable runs close to power cables, shielded cable must be used. If a conduit is used it must be sealed to prevent condensation in the sensor capsule. The outdoor sensor should be connected, e.g. to the heat pump with fixed condensing.

Check the pipe system for leaks. P SÄV Filling and venting the brine system SF EXP To fill the brine system, mix about 3% antifreeze with water in an open container and connect with the filling pump and hoses as illustrated. Close the valve on the main pipe between the service connections and fill through the service connection closest to the heat pump until the liquid returns in the return hose. Then make the following settings on the control panel. Set the switch to 1. Stängs Closes AV Go to menu Brine-pump, EP-drift in the service menu. AV Set Brine-pump in mode 1 and press Operating mode. Set EP-drift in mode 1 and press Operating mode. BK / JK Button for Operating mode The heat pump cannot start because it is in operational mode "EB" (electric boiler mode only). The brine pump and the filling pump are now operating together. Let the liquid circulate via the mixing vessel until there are no more air bubbles in the liquid in the return hose. Now stop the brine pump by resetting "Brine-pump" to the "" position. Stop the filling pump and clean the screen in the particle filter. Now start the filling pump again. Open the valve on the main pipe between the service branches while the filling pump is still operating (to expel the air between the branches). Now close the valve at the return hose. Then pressurise the system (to max 3 bars) using the filling pump. Reset to normal mode by setting "EP-drift" to "".

22 For the Installer Commissioning and adjusting Filling the heating/heating medium systems Fill the heating medium system with water to the required pressure and vent the system. Readjusting, collector side Check the pressure level in the expansion vessel (85). If the pressure drops, the system should be replenished. Start-up and inspection 1. Set the switch to Check the settings on the control system, and adjust so there is a heating requirement. 3. Go to the Brine-pump, EP-drift menu in the service menu. Set Brine-pump in pos 1 and press Operating mode. Set EP-drift in pos 1 and press Operating mode. 4. Check that the brine and heating medium pumps are vented and if necessary help the pumps to start. 5. Go to the Brine In, Brine O menu. Ensure that the temperature corresponds with the soil/rock temperature, which indicates the brine flow. 6. Go to the Brine-pump, EP-drift menu in the service menu. Set EP-drift to. The compressor should start within a few minutes. If this does not happen, check that there is heating or hot water requirement. 7. Go to the Brine In, Brine O menu. Read the brine temperatures. The difference between these two temperatures should be 2 5 C when the system has come into balance. A high difference indicates a low brine flow. A low difference indicates a high brine flow. 8. Particular attention should be given to the level in the brine system when initially using the heat pump. Some toppingup may be necessary. 9. Read the heating medium temperatures WW-out and WW-in. The difference between these two temperatures, with floating condensing, should be 5-1 C when the heat pump heats the heating water without additional heat. A high difference could depend on a low heat medium flow. 1. Checking the cooling operation - Check the settings on the control system, and adjust so there is a cooling requirement. - Check that the external circulation pumps start and that the compressor cools. - In the event of no flow, the flow monitor does not give a start signal to the compressor. 11. Fill in the commissioning report on page Set the control system to suit the needs of the building. Readjusting, heating 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 is stable (correct pressure and all air eliminated) the automatic heating control system can be set as required. 2

23 For the Installer Setting of heating/cooling automatic system Setting of heating/cooling automatic system Setting with diagrams is equipped with an outside controlled heating/cooling control system. 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, see section Control Setting heat/cooling, page 6. 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/cooling control's curve coefficient can be read. The Increase/Reduce room temperature knob (heating curve offset) can then be set. A suitable value for underfloor heating is -1 and for radiator systems -2. Cooling curve offset Calculated flow temperature framledningstemp.
