INSTALLER SETTING
Connectivity - 3rd party boiler
Either the heat pump or the boiler is used for space heating (Bivalent-alternative operation)
Two different modes are available to switch-over between heat pump and boiler:
- Manual: The boiler is activated and de-activated by User setting ‘Function/3rd party boiler’.
- Auto: The boiler output is activated based on outdoor temperature.
The bivalent temperature (Default: -7 °C) and the switch-over hysteresis (Default: 4 K) can be
adjusted by setting.
1) Seasonal auto temp/Outdoor temp/O1
2) Connectivity/3rd party boiler/Temp
3) Connectivity/3rd party boiler/Hysteresis
4) Seasonal auto temp/Outdoor temp/O2
NOTE
Prices for electricity and fuel, as well as the maximum capacity of the heat pump must be
considered when changing the Bivalent temp.
