(1) With swimming pool heating set as priority (prog. no. 2065), the swimming
pool will be heated before the storage tanks.
Charging time relative prio (3825)
If the preferred storage tank corresponding to the charging control not be
charged, during the time set here the priority goes to the next storage tank
or the swimming pool.
Waiting time relative prio (3826)
Transfer of priority is delayed by the time selected here.
Waiting time parallel op (3827)
Parallel operation is feasible when using solar primary pumps subject to
there being sufficient solar energy available. For this, in addition to the
storage tank currently being heated, the next storage tank in the priority
order can also be heated in parallel. The storage tank switching on for par­
allel operation can be delayed and stepped by the value set here.
Delay secondary pump (3828)
Operation of the secondary pump of the heat exchanger/indirect coil can
be delayed to enable any cold water that may be present to be flushed
through the primary circuit first by the pump.
Collector start function (3830)
If the temperature at the collector with the pump turned off is not meas­
ured correctly (e.g. with vacuum tubes), then a periodic switching on of the
pump is possible.
Caution
The temperatures at certain collectors cannot be measured cor­
rectly 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) and Collector start function
off (3833)
The time when 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 selected here, the great­
er the temperature rise must be.
Collector frost protection (3840)
In order to prevent freezing of the collector, the collector pump will be acti­
vated in case of frost danger.
Collector overtemp prot (3850)
In case of overheating danger, charging of the storage tank is continued in
order to remove heat. When the storage tank safety temperature has been
reached, charging of the storage tank will be interrupted.
Evaporation heat carrier (3860)
Pump protecting function, to prevent overheating of the collector pump in
case of evaporating danger of the heat carrying medium due to high col­
lector temperature.
