Speed controller RDCZ9-15-WH

The RDCZ series are residential HVAC controllers used to control AC fans, voltage controllable motors, lighting or other applications. They feature a wide supply voltage range 110—230 VAC / 50—60 Hz and a variable control output signal between an adjustable minimum and maximum level. The controller can work in 2 modes. In Automatic mode it is a demand-based controller with adjustable setpoint that can be connected to a broad range of Sentera sensors. In Manual mode, the RDCZ works as a full-featured potentiometer. The settings are easily adjustable either via the 3-button interface equipped with a 7-Segment LED display, via our 3SModbus software application or via the Sensistant configurator
