Page 8: About Your Heat Pump
About your heat pump Product description The heat pump is a heating system for heating and hot water if an external water heater is installed (accessory). It has a compressor developed solely for heat pumps. The heat pump is equipped with control equipment which is presented in a graphical display. - Page 9 The heat pump is, therefore, a very environmentally friendly and eco- nomical way of heating a house. Figure 1. The principles of the heat pump The heat pump has four separate fluid circuits • Brine circuit (1) – is a fluid (brine) filled hose lowered into a lake, buried in the ground or lowered into bedrock.
-
Page 10: Hot Water Tank (Option)
• Heat transfer fluid circuit (8) – is the water that transports the heat/ energy to the heating system and the hot water tank. • Hot gas circuit – is a high temperature circuit for the hot water circuit’s final heater. If the heat pump is not connected to any water heaters, the hot gas circuit does not need to be connected. -
Page 11: Operating Instructions
Operating instructions Control panel 3.1.1 Function description The heat pump has an integrated control system which automatically cal- culates the heat demand in the house to ensure that the correct amount of heat is produced and emitted where necessary. There are many differ- ent values (parameters), which are required in order to do the calculation of the heat demand. - Page 12 display always shows the set ROOM value, the operating mode and the status of the heat pump. ROOM 20°C NO HEAT DEMAND OPERAT. AUTO Figure 2. Display, keypad and indicator. (20°C) Position Description The display text and symbols are only shown as examples. Certain symbols cannot be displayed at the same time.

See the installation instructions when filling brine. Symbol explanation Used when filling Connected to brine circuit Figure 4. Filling the brine system Checking the water level in the heating system The line pressure of the installation must be checked once a month. Ensure that heating system has the necessary pressure, however, not above max- imum pressure of 6 bar. -

regularly, the water tank might be damaged. It is quite normal that the safety valve lets out small amounts of water when the water tank is being charged, especially if a lot of hot water was used previously. Both safety valves can be checked by turning the cap a quarter of a turn clockwise until the valve lets out some water through the overflow pipe. -
