3 Star DHW comfort setting
This boiler is equipped with advanced soft-
ware that facilitates an enhanced domestic
hot water delivery system; this system re-
duces the waiting time at the hot water draw
off points to a minimum and also ensures
limited water wastage.
Please ensure if you decide to activate the
built in 3 star comfort function that the first
DHW draw off point is at a sufficient dis-
tance to avoid excessively hot water being
delivered to the draw off point.
