Comfort temperature
The bypass valve settings can be adjusted using a
programmed comfort temperature (required indoor
temperature). The comfort temperature can be
programmed in parameter M10-99 or directly with
the display. The comfort temperature cannot be set
via the display if the comfort temperature control has
not been set.
It is best to set the comfort temperature to the
same temperature as the room thermostat (of the
central heating system).
