6.15.4 Maximum charging temperature, maximum safety
temperature
The storage tank is charged with solar energy up to the set Charging temp max at
sensor B31/B41. If sensor B31/B41 is not available, sensor B3/B4 is used.
As soon as the maximum charging temperature in the storage tank is exceeded,
charging is canceled (storage tank temperature > Charging temp max). If the storage
tank temperature drops below the maximum charging temperature by 1 K, charging is
enabled again (storage tank temperature < Charging temp max – 1 K).
Caution!
Function Protective collector overtemperature can reactivate the collector
pump until the maximum storage tank temperature is reached.
Note!
When using 2 sensors (B3 + B31 or B4 + B41), charging is aborted whenever one of
the temperatures acquired by the 2 sensors lies above the maximum charging
temperature.

Note!
Since the swimming pool temperature setpoint (Setpoint solar heating (2055)) equals
the maximum charging temperature, the swimming pool is always charged until this
temperature level is reached.
