- Lay out of internal piping 2
- Allows isolation of the indoor unit water circuit side from the residential water circuit side 3
- Allows readout of the water pressure in the water circuit 3
- C d e f 3
- Circulates the water in the water circuit 3
- Components indoor unit 3
- Contains the main electronic and electrical parts of the indoor unit 3
- Controls whether the water is used for space heating or the domestic hot water tank 3
- Determines the water and refrigerant temperature at various points in the circuit 3
- Empties the full tank 3
- Gives feedback to the interface about the actual flow based on this information and other the interface adjusts the pump speed 3
- P412945 1 2015 6 addendum to the documentation set 3
- Prevents excessive water pressure in the water circuit by opening at 3 bar 3
- Provides additional heating in case of cold outdoor temperatures also serves as backup in case of malfunctioning of the outdoor unit 3
- Remaining air in the water circuit will be automatically removed via the air purge valve 3
- Removes dirt from the water to prevent damage to the pump or blockage of the heat exchanger 3
- The protector activates when the temperature of the backup heater becomes too high 3
- Addendum to the documentation set 4p412945 1 2015 6 4
- D087616 1 4
- Dimensions and service space indoor unit dimensions pay special attention towards position of water piping connections and of refrigerant piping connections 4
