Space Heating and Domestic Hot Water
The room thermostats are not connected to the Mono unit but to a motorized valve. Each room’s temperature is regulated
by the motorized valve on its water circuit. Domestic hot water is supplied from the domestic hot water tank connected to
the Mono unit. A bypass valve is required.
