Unit operation and space heating：
When a room thermostat is connected to the unit and when there is a heating request from the room thermostat, the unit will
start operating to achieve the target water flow temperature as set on the user interface. When the room temperature is above
the thermostat set point in the heating mode, the unit will stop operating. The circulation pump (1.8) and (10) will also stop
running. The room thermostat is used as a switch here.
Make sure to connect the thermostat wires to the correct terminals, method B should be selected (see "For room
thermostat" in 9.7.6 connection for other components). To correctly configure the ROOM THERMOSTAT in the FOR
SERVICEMAN mode see 10.7 Field settings/ROOM THERMOSTAT.
