Space Heating, Space Cooling and Domestic Hot Water
Floor heating loops and fan coil units are used for space heating and fan coil units are used for space cooling. Domestic hot
water is supplied from the domestic hot water tank connected to the Mono unit. The unit switches to heating or cooling
mode according to the temperature detected by the room thermostat. In space cooling mode, the 2-way valve is closed to
prevent cold water entering the floor heating loops.
