Charging time relative prio
(3825)
If the preferred storage tank corresponding to the charging control not be char-
ged, during the time set here the priority goes to the next storage tank or the
swimming pool.
Waiting time relative prio
(3826)
The transfer of the priority of the time set here is delayed.
Waiting time parallel op
(3827)
With sufficient solar capacity, with use of solar charging pumps a parallel operati-
on is possible. During this the next storage tank in the priority sequence can be
loaded parallel to the current loaded storage tank. The storage tank switching on
for parallel operation can be delayed and staged by the value set here.
Delay secondary pump
(3828)
So that possible existing cold water can be first rinsed through the pump in the
primary circuit, the operation of the secondary pump of the heat exchanger can
be delayed.
Collector start function
(3830)
If the temperature at the collector with the pump turned off not be measured
correctly (e.g. with vacuum tubes), then a periodic switching on of the pump is
possible.
The temperature on a certain collector cannot be measured correctly, if the pump
is switched-off. For this reason, the pump must be activated from time to time.
Min run time collector pump
(3831)
The collector pump is periodically switched on for the running time set here.
Collector start function ON
(3832)
Collector start function OFF
(3833)
The time that the collector start function starts or stops is set here.
Collector start funct grad
(3834)
As soon as there is a temperature increase on the collector sensor, the collector
pump switches on. The higher the value here is set, the larger the temperature
increase must be.
Collector frost protection
(3840)
In order to prevent freezing of the collector, the collector pump will be activated
in case of frost danger.
Collector overtemp prot
(3850)
In case of overheating danger, charging of the storage will be continued, to remo-
ve heat. When reaching the storage safety temperature, charging of the storage
will be interrupted.
