If the collector temperature exceeds the temperature set here, the solar pump is off.
If the collector temperature falls below the temperature set here, the solar pump is off, even 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.
Vacuum tube collector pump anti-seize function switched off.
The solar pump 2 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.
2nd vacuum tube collector pump anti-seize function switched off.
Frost Protection - 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! This function is not a substitute for glycol within the solar circuit!
Mediterranean climate function switched off.
If the collector temperature falls below the value set here, the solar pump is on.
Collector array 1 is actively cooled via the connected emergency cooler when 100 °C is exceeded
(= Max. collector temp. – 20 °C).
Collector cooling function switched off.
1st cylinder is not heated.
If the temperature set here is exceeded in cylinder 1, the solar pump is off.
2nd cylinder is not heated.
If the temperature set here is exceeded in cylinder 2, the solar pump is off or the valve is closed (depending on which
function is selected).
The swimming pool is not heated.
If the temperature set here is exceeded, the solar pump is off or the valve is closed (depending on which function is
selected).
3rd cylinder is not heated.
If the temperature set here is exceeded in cylinder 3, the solar pump is off, the pump is off or the valve is closed
(depending on which function is selected).
The cylinder set here is the high priority cylinder;  function Cylinder 2 with valve (B), Cylinder 2 with pump (C) and
Cylinder 3 with valve (N). The cylinders are heated in the following order:
Priority cylinder 1: 1 – 2 or 1 – 2 – 3
Priority cylinder 2: 2 – 1 or 2 – 1 – 3
Priority cylinder 3: 3 – 1 – 2
If the low priority cylinder is currently being heated, the solar pumps are switched off at the regular intervals specified
here.
While the solar pumps are switched off ( Test interval priority cyl.), the temperature in the collector increases and
the required temperature differential for heating the high priority cylinder may be reached during this period.
versa.
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.
