Temperatures that the collector must have at the least in order to begin charging
a swimming pool.
For several combined exchangers in the system, the loading sequence for the
combined storage tank can be defined by setting the loading priority.
- None: each storage tank is loaded alternately for a temperature increase of 5°C,
until each setpoint has reached level A, B or C (Tab. 1). If all setpoints are
reached, the setpoint of the next level is approached.
- Drinking water storage tank : the drinking water storage tank is loaded during
the solar charging in each level (A, B, or C) according to priority. First afterwards
are more consumers loaded in the same level. If all the setpoints are reached,
the setpoints of the next level are approached. Again the loading of the drink-
ing water storage tank has priority.
- Buffer storage tank : the buffer storage tank is loaded during the solar charging
in each level (A, B, or C) according to priority. First afterwards are more consum-
ers loaded in the same level. If all the setpoints are reached, the setpoints of the
next level are approached. Again the loading of the buffer water storage tank
has priority.

If the preferred storage tank corresponding to the charging control not be charg-
ed, during the time set here the priority goes to the next storage tank or the
swimming pool.
The transfer of the priority of the time set here is delayed.
With sufficient solar capacity, with use of solar charging pumps a parallel opera-
tion 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.
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.
If the temperature at the collector with the pump turned off is 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.
