Residential fan speed controller RDCZ9-15-BK

Variable speed controller with display. It controls single-phase motors. The maximum current is 1,5 A. The AC fan speed is regulated by varying the motor voltage via phase angle control - Triac technology. In manual mode, the requested speed can be selected via the 3-button interface. This can be done stepless or in 2-10 steps. When a HVAC sensor is connected, automatic mode can be activated. Now, the fan speed will be automatically optimised in function of the ambient temperature, relative humidity, CO2 concentration, air quality (TVOC concentration), CO concentration or differential pressure. The setpoint and all parameters can be adjusted via the 3-button interface or via Modbus RTU. The supply voltage is 110-230 VAC / 50-60 Hz. The anthracite enclosure allows surface mounting or inset mounting.
