Domesc Hot Water Comfort Modes are sengs that would either supply quicker delivery of hot
water to xtures or save energy in the boiler operaon.
Eco Mode (Default)
The boiler operates and produces hot water; however, it will not maintain the primary heat
exchanger temperature for quicker hot water producon. This selecon saves some energy,
but requires a longer me to provide hot water to the hot waterxtures.
Comfort Mode
The boiler maintains the primary heat exchanger temperature to quickly deliver hot water to
the plate heat exchanger. This selecon provides the quickest delivery of hot water to hot
water xtures, but uses more energy.
By default, Eco mode is enabled (turned on). To enable (turn on) comfort mode, press the Eco
buon on the controller.
