If the buffer storage tank had to be charged via "Charging temp max", recooling to the
recooling temperature set here takes place as soon as possible.
For recooling the buffer storage tank, the 2 following functions are available:
The heat energy can be drawn off either by space heating or the DHW storage tank.
The function is activated or deactivated on this operating line. This can be selected
separately for each heating circuit (menu "Heating circuit 1...").
When the collector is cold, the energy can be emitted to the environment via the
collector's surfaces.
Off.
Recooling via the collector is deactivated.
Summer
Recooling via the collector is permitted in summer only.

4761 Forced charging electric
The electric immersion heater in the buffer storage tank is released for forced
charging when none of the heat sources is able to deliver heat, and in the case of
active frost protection for the buffer storage tank.
The electric immersion heater in the flow is switched on for forced charging if the heat
pump does not reach the setpoint and if, on operating line 2880, "Use electric flow",
setting "Complement HP operation" is used, or when the heat pump works in
emergency operation and on operating line 2880, "Use electric flow", setting
"Substitute" is used.
This defines the sensor to be used for charging with an electric immersion heater.
B4
The electric immersion heater is switched on and off via sensor B4.
B42 / B41
The electric immersion heater is switched on via sensor B41 and off via sensor B42.
If, within one minute after triggering forced charging, none of the heat sources in the
system is put into operation for forced charging of the buffer storage tank, the electric
immersion heater can ensure it.
No
Electric immersion heater K16 is not used for forced charging.
