About bivalent
The purpose of this function is to determine which heating source can/will provide
the space heating, either the heat pump system or the auxiliary boiler.
# Code Description
[9.C.1] [C-02] Bivalent : Indicates if the space heating is also
performed by means of another heat source than
the system.
▪ 0 No : Not installed
▪ 1 Yes : Installed. The auxiliary boiler (gas boiler,
oil burner) will operate when the outdoor
ambient temperature is low. During bivalent
operation, the heat pump is turned off. Set this
value in case an auxiliary boiler is used.
▪ If Bivalent is enabled: When the outdoor temperature drops below the
bivalent ON temperature (fixed or variable based on energy prices), the space
heating by the heat pump stops automatically and the permission signal for the
auxiliary boiler is active.
▪ If Bivalent is disabled: Space heating is only done by the heat pump within the
operation range. The permission signal for the auxiliary boiler is always inactive.
