3850 Collector overtemp prot
If there is a risk of overtemperature at the collector, storage tank charging is continued
to reduce the amount of surplus heat. When the storage tank safety temperature is
reached, charging will be stopped.

3860 Evaporation heat carrier
If there is a risk of the heat carrying medium evaporating due to high collector
temperatures, the collector pump will be deactivated to prevent it from reaching
excessive temperatures. This is a protective pump function.
The solar pump motor speed is limited by a minimum and maximum permitted speed.

The 24-hour and total solar energy yield (operating lines 8526 and 8527) is calculated,
based on these data.
Since the mixing ratio of the collector medium has an impact on heat transmission, the
type of antifreeze used and its concentration must be entered in order to be able to
determine the energy yield.
The flow rate in l/h of the pump used must be determined and serves for calculating the
volume delivered.
