If the preferred storage tank cannot be charged in accordance with charging
control, priority is transferred to the next storage tank or the swimming pool for the
period of time set (e.g. temperature differential between collector and storage tank
too great).
As soon as the preferred storage tank (according to setting "Charging prio storage
tank") is again ready to be charged, the transfer of priority will immediately be
stopped.
If the parameter is deactivated (---), priority always follows the settings "Charging
priority storage tank".
During the period of time set, the transfer of priority is delayed. This prevents
relative priority from intervening too often.
If solar output is sufficient and solar charging pumps are used, parallel operation is
possible. In that case, the storage tank of the priority model can be the next to be
charged at the same time, in addition to the storage tank to be charged next.
Parallel operation can be delayed by introducing a waiting time. This way, in the
case of simultaneous operation, switching on of the storage tanks can be effected
in steps.
Setting (---) disables parallel operation.
To remove any existing cold water from the primary circuit, operation of the
secondary pump of the external heat exchanger can be delayed.

If the temperature at the collector (especially in the case of vacuum tubes) cannot
be correctly acquired when the pump is deactivated, the pump can be activated
from time to time. This setting defines the interval at which the collector pump is put
into operation. Then, the pump will operate for the set time "Min run time collector
pump" (3831).
The collector pump remains switched on at a minimum for the parameterized
minimum running time.
