Max. H-Gen temperature to be set, set as for max. fl ow temperature (after termination
of screed function reset max. temperature to the value required).
If the screed function is activated for the unmixed circuit, all the other circuits (MC, DHW) are switched off.
In alternation with the basic display of the controller, the activated screed heating is displayed giving some information
about the remaining term in days „screed - 18“.
