(3815) The switching-on and switching-off point of the collector pump is set with these
functions. Basis is the temperature difference between collector temperature and
storage temperature of the buffer.
In addition to the temperature difference, reaching a certain minimum collector
temperature is necessary for the buffer storage charging process.

(3817) For exceeding or not reaching the difference between solar collector temperature
and swimming pool temperature, the solar pump is switched on and off.
