▪ For the additional zone:
- The external thermostat is directly connected to the indoor unit.
- The desired room temperature is set via the external thermostat and the
thermostatic valves of the radiators in each room.
- The heating demand signal from the external thermostat is connected to the
digital input on the indoor unit (X2M/35a and X2M/30). The indoor unit will
only supply the desired additional leaving water temperature when there is an
actual demand.
