Note!
When using setting - - -, the general temperature differential solar (Temp diff on
(3810) and Temp diff off (3811)) is adopted.
When charging the storage tank via the heat exchanger, the temperature differential
between collector and storage tank/swimming pool must be sufficient, and the collector
must have reached the minimum charging temperature for the storage tank/swimming
pool.
