The RDCV9 can be used as a digital controller to control EC fans based on temperature or humidity using an additional sensor or also as a manual speed controller.
In manual mode, the RDCV is a speed controller for EC fans with three buttons and a seven-segment LED display. It has an optional analog or modulating signal 0-10 VDC, 0-20 mA, 0-100% PWM. It can be used for direct control of an EC fan.
In automatic mode, the RDCV is a temperature, humidity based controller that can control the EC fans if combined with temperature / humidity sensors. When such a sensor is connected, the RDCV will recognize which parameters can be controlled and will allow you to select a parameter. Maintaining the set temperature or humidity is based on the control of the PI controller.
