Manual or demand based fan speed controller for AC fans with single phase voltage controllable motor up to 1,5 A. The requested fan speed can be selected manually via the 3-button keyboard or automatically. In automatic mode, a Sentera HVAC sensor can be connected to the RDCZ controller to regulate the fan speed in function of the measured temperature, relative humidity, CO2 concentration or differential pressure. The enclosure allows inset mounting or surface mounting.
