Residential fan speed controller RDCV9-AD-BK

Digital potentiometer and HVAC controller. The enclosure has a black colour and contemporary style. The analogue output can control EC fans, AC fan speed controllers, frequency inverters or damper actuators. In manual mode, the requested output value can be selected via the 3-button interface. The output type is selectable. This analogue output can be continuous variable or it can be divided in 2-10 equal steps. The minimum and maximum values are adjustable. When a HVAC sensor is connected, automatic mode can be activated. Now, the analogue output is controlled by 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 communication. The supply voltage is in the range of 110 - 230 VAC. The enclosure allows surface mounting or inset mounting.
