15. Bivalent point
Parameters Description Unit
Bivalent point The outdoor temperature from which
part of the heat load is taken over by the
auxiliary heater, is set here. It should not
be switched on until the output that is
demanded is greater than the heat pump
can provide, due to the low outdoor tem-
perature.
°C
X Outdoor air temperature [°C]
Y Heating output [kW]
1 Standard outdoor temperature
2 Bivalent point
3 Heating limit
4 Electric auxiliary heater share
5 Surplus energy
6 Max. heat pump heating output
7 Required heating output at standard outdoor
temperature
8 Min. heat pump heating output
9 Modulation range
Note
If the bivalent point is set too high, there may be
higher running costs due to the auxiliary heater
being switched on too early.
If the bivalent point is set too low, the heat pump
may not reach the required temperatures for DHW
and heating.
