4.1.6 Forced pump operation (anti-locked)
If the pump has not been turned on for 24 hours, it is turned on by force between 12:02
and 12:03 to prevent that it gets stuck in long term idle periods.

4.1.7 Collector Antifreeze
Solar systems with no antifreeze medium can be run in regions where frost just appears
sporadically. In case that the temperature really should drop below the dew point, the
controller is able to turn on the pump in order to prevent a freezing of the collector.
Operation: The collector pump is turned on if the temperature at the collector sensor
drops below 5 °C. At 6 °C it turns off again, but running for the minimum running time
set.
The following icon additionally appears
if the pump is turned on because for means of
antifreeze.

Notes:
This function leads to transferring the heat out of the storage to the collector. It is
only suitable for regions with mild climate. The storage may not be able to provide
sufficient energy during strong freeze periods to protect the collector from freezing.
This function should not be used in system variants with antifreeze.
