Underfloor temperature controller with timer, surface-mounted, remote sensor NTC2K, backlighting


Underfloor temperature controller with timer, surface-mounted, remote sensor NTC2K, backlighting

Electronic floor temperature controller for time-dependent control of temperatures in closed rooms. Suitable for floor, edge zone, bathroom, ceiling, tiled stove, marble, wall heating, or temperature control systems up to 3000W. Can be used as a master (pilot controller) for lowering the temperature of other controllers. Controllers of the FETR, FTR, and RTBSB series are suitable as slaves (satellite controllers) for this purpose. Simple operation by means of direct selection keys. In case of sensor breakage or sensor short-circuit, the heating is activated with a duty cycle of 30% to prevent cooling or frost damage in the room. Temperatures below -20°C are also evaluated as the sensor break and the emergency function is triggered. The unit can also be mounted on a flush-mounted box by means of an adapter plate.
