Function description
If the collector temperature exceeds the temperature set here, the solar pump is off.
if all conditions for switching on have been met.
The solar pump is switched on briefly every 15 minutes between 6:00 and 22:00 in order to
pump the heated heat transfer medium to the temperature sensor.
Evacuated tube collector pump anti-seize function switched off.
If the collector temperature falls below the set value ( Start temp. S.Eur. fct.), the solar
pump is on. This pumps hot water from the cylinder through the collector. If the collector
temperature exceeds the set temperature by 2 K, the pump is off.
This function is intended solely for regions where the high temperatures mean that damage
from freezing usually cannot occur.
Caution! The Mediterranean climate function does not provide absolute protection from
damage caused by freezing. The system may need to be operated with heat transfer fluid
instead of water only!
Mediterranean climate function switched off.
If the collector temperature falls below the value set here, the solar pump is on.
Function description
Cylinder 1 is not heated.
Cylinder 3 is not heated.
If the differential set here between the cylinder temperature and the temperature at the
heat exchanger is exceeded and all conditions for switching on have been met, the
cylinder primary pump is on.
If the differential between the cylinder temperature and the temperature at the heat
exchanger falls below the value set here, the cylinder primary pump is off.
If the temperature at the external heat exchanger falls below the temperature set here,
the cylinder primary pump is on. This protects the heat exchanger from damage from
freezing.
