Operating phase:
The flow temperature sensor has detected
that the current flow temperature is higher
than the flow temperature setting on the
BC10, or that it is higher than the flow
temperature. Calculated according to
heating requirements, or that it is higher
than the flow temperature calculated for the
DHW mode.
Off The room
temperature is not
possibly reached.
