7.2 Maximum storage tank temperature
If the lower area of the storage tank (T) reaches
the set maximum storage tank temperature
(factory setting 60 °C), charging is stopped. A tem-
perature of 3 K below the maximum storage tank
temperature must first be reached before charging
can be resumed. The following displays appear:The
pump symbol does not move
The sun symbol is displayed
The max indication flashes in the storage tank
symbol
7.3 Maximum collector temperature
During periods of high solar irradiance, the tempera-
ture (T1) of the heat transfer fluid can exceed 130°C.
The heat transfer fluid evaporates. In this case, the
pump is stopped for protection purposes until the
temperature drops below 17°C.
The following displays appear:
The pump symbol does not move
The sun symbol is displayed
The vapour symbol flashes
7.4 Tube collector function
For reasons of construction the collector temperature
(T1) can only be imprecisely recorded with vacuum
tube collectors (in many cases there are no immersion
sensors; the sensor is outside the collector pipe). In
