Storage tank priority
Depending on the usage, it could make sense to reach a higher temperature in one of
both storage tanks or to reach a uniform allocation of the collected energy. The
parameter Type of storage tank priority is used to determine the solar controller mode of
operation.

The following table
Priority
mode Function Description
1 hard priority
Max Storage tank 2 is only charged if the maximum temperature in
storage tank 1 has been reached
2 hard priority
Min. Storage tank 2 is only charged if the minimum temperature in
storage tank 1 has been exceeded.
(defined at auxiliary heating, see section 5.14)
3 soft priority Storage tank 1 is always charged if the collector temperature is
sufficient to charge it. If not sufficient to charge storage tank 1
but sufficient to charge storage tank 2, charging of storage tank
2 is initiated. After the lapse of the specified time (Charging
time for low priority storage tank, WE15 minutes), charging is
interrupted for the minimum idle time (see section 5.1). At the
end of this interruption it is newly decided if the temperature is
sufficient to charge storage tank 1.
4 alternating
charge The storage with the lowest temperature is charged first. Once
the currently charged storage tank becomes warmer by more
than 5K compared to the other one, charging is switched to the
colder storage tank. Switching can occur several times.
5 no priority Both storages tank are charged having equal priority, that is,
the storage tank with the lower temperature is charged first. If
charging is not interrupted, the storage tank is charged to its
maximum temperature and only then switched to charge the
other storage tank.
5.3 Swimming pool
The solar controller SOL3 is suitable for the solar heating of swimming-pools. Any usable
solar energy is transferred in a swimming pool, which can be selected as a storage tank
1 or storage tank 2 with the given storage tank priority mode.
The maximum storage tank temperature (temperature of the swimming-pool) is to the
need to adapt.
