Room control for heating/cooling with 6-way regulating ball valve, room operating unit and dew point monitoring

The room temperature measured by the room operating unit (ROU) or room temperature sensor (RTS)
is compared with the specified room temperature setpoint and converted by the control system
into the corresponding output signal for actuator control.

Heating or cooling mode can be selected manually. In automatic mode, the system automatically switches
from heating to cooling depending on whether the actual temperature is above or below the setpoint.
