If the collector temperature is higher
than 40 °C between 11 p.m. and 5.00 a.m.
or the present temperature difference is
higher than the switch-on temperature
difference, this can indicate a heat return
current (e.g. due to defect of non-return-
valve).
This message is to be seen as a warning
and it should always be considered in re-
lation to the outdoor temperature.
If a malfunction occurs, a message is displayed in the display
of the controller:

circuit with indication of the respective
sensor.

cation. But if the fault is still present, the
controller should be returned to the
manufacturer.

clock of the controller. Please switch-off
