Aux. heating T-biv.
dependent
Backup heater is only released if the temperature set in the [Equilibrium
Temp] parameter is undercut.

Setting influences the effect of the potential-free AUX switching contact
(toggle switch output A) defined in the [AUX switching function] parameter.
Only if [Equilibrium function] parameter = heating up T-bivalence:
Outside temperature as of which the optional heater booster is activated to
support room heating. The bivalence temperature is relevant to operation
of the optional heater booster due to a backup request (room heating
mode). The temperature of the temperature sensor (information value Tem-
perature
A
) integrated in the heat pump outdoor unit is used for this.
