min transfers in Suspend mode. When
there is no signal from room termostat
or there is non-fulllled requirement for
DHW, the burner will re up.
In “CH + DHW” mode when DHW
(Domesc hot water) requirement is
fulllled and there is a signal from room
termostat, the burner burns 5 min at max
power, followed by transfer to power
level 2. Aer 5 min burner transfers to
power level 1 and aer 5 min transfers
