For charging the storage tank via the heat exchanger a sufficiently large tempera-
ture difference between the collector and storage tank is necessary. In addition
the collector must have reached the minimum charging temperature.

For exceeding or not reaching the difference between solar collector temperature
and swimming pool temperature, the solar pump is switched on and off.

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 (see
Tab. 2 (Page 54)
). If all setpo-
ints are reached, the setpoint of the next level is approached.
DHW storage tank:
The DHW storage tank is preferred during solar charging. It is
charged in each level A, B or C (see below) with priority. Only afterward is the fol-
lowing consumer in the same level charged. As soon as all setpoints in one level
are reached, the ones in the next level are approached, whereby the DHW storage
tank again has priority.
Buffer storage tank:
The buffer storage tank is preferred during soar charging. It is
charged in each level A, B or C (see
Tab. 2 (Page 54)
) with priority. Only after-
ward is the consumer next to it in the same level charged. As soon as all setpoints
in one level are reached, the ones in the next level are approached, whereby the
buffer storage tank again has priority.
