Page 5: Important Information
Important information Note! If the installation is not used during the winter, the heating system must be drained of water, otherwise there is a risk of frost damage to the installation. The system can be considered maintenance free but certain checks are necessary. -
Page 6: Safety Precautions
Safety precautions 1.1.1 Installation och underhåll DANGER! Only authorized installers may install, operate and carry out maintenance and repair work on the heat pump. DANGER! Only authorized electricians may modify the electrical installation. DANGER! DANGER TO LIFE! Only authorized refrigeration technicians may work on the refrigerant circuit. -
Page 7: Protection
Protection 1.2.1 Korrosionsskydd Due to the risk of corrosion, avoid using different types of sprays in the vicinity of the heat pump. This particularly applies to: • Solvents • Chlorinated cleaning agents • Paints • Adhesives User manual 086U6297 Rev. 6 EN – 5... -
Page 8: About Your Heat Pump
About your heat pump Principles of function A heat pump utilises the free energy from the sun and that is also found in a natural heat source, such as rock, ground, ground water or air. The heat pump can be compared to a reversed refrigerator; in a refrigerator heat is transferred from the inside of the refrigerator to the outside, whereas in a heat pump, the solar energy that is stored in a heat source is transferred to the inside of the house. -
Page 9: Components
separate fluid circuits are required. The figure below shows the different circuits and how they work together in the transfer of heat energy. A fluid (brine) (A) filled hose is lowered into a lake, buried in the ground or low‐ ered into bedrock. - Page 10 Heat enters the house via a water borne heating system. The heat pump supplies as much of the heat demand as possible before auxiliary heating is engaged and assists. 8 – User manual 086U6297 Rev. 6 EN...

Page 12: Outdoor And Defroster Function
Outdoor and defroster function Atria models are equipped with an outdoor unit that uses air as a heat source down to -20°C. The outdoor unit has a coil where brine recovers free energy from the outside air. It also has a fan that increases the airflow through the coil. - Page 13 • The shunt valve closes the flow of hot brine from the defrosting tank. • Operation returns to normal. The unit (Atria models) consists of the following basic components: Heat pump unit • Compressor • Stainless steel heat exchanger •...

Page 14: Passive Cooling Function
Passive cooling function Note! Not sold on all markets. Heat pump Comfort is equipped with an extra heat exchanger to use the passive cooling effect from the brine. Because the temperature in the collector (borehole or equivalent) is lower than the indoor temperature, the temperature difference can be exploited to cool the radiator circuit. -

- Page 18 The hot water heaters for Atria models differ from the other heat pumps in that the function for defrosting the outdoor unit is different. The only difference between an Atria/Atria Optimum and an Atria Duo/ Atria Duo Optimum is that the water heater is integrated in Atria/Atria Optimum and a separate unit for Atria Duo/Atria Duo Optimum.

Page 19: Control Computer
Control computer Control system The heat pump has an integrated control system which automatically calculates the heat demand in the house to ensure that the correct amount of heat is produced and emitted where necessary. There are many different values (parameters), which are required in order to do the calculation of the heat demand. - Page 20 tings and values. During operation, the 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 4. Display, keypad and indicator.
