For its operation, a control sensor must be coupled to the control element. It can be the internal sensor, if no remote control
sensor has been assigned to the zone in which the thermal actuator is mounted or a remote sensor assigned to the zone in
which the thermal actuator is mounted.
Note: for one x zone and no remote sensor has been assigned, the control is performed taking into account the internal sensor
if this is not already in use for another zone.
If for a zone, the “limit control with room sensor control” is active (for example for zone 1 if

A SLAVE_X controller can manage up to 4 zones. In each zone, a thermal actuator is mounted. The thermal actuator is con-
trolled in heating and cooling mode based on the control sensor of the considered zone, the operating setpoint of the zone
