Product description
The RDCV EC Fan Speed Controller is a digital potentiometer and HVAC controller that offers precision in ventilation management with advanced features and a modern design.
Its intuitive 3-button interface allows for easy fine-tuning of your system in manual mode.
This controller can operate EC fans, AC fan speed controllers, frequency inverters, or damper actuators. The output can be continuously variable or divided into 2-10 equal steps with adjustable minimum/maximum values.
It operates within a 110 - 230 VAC supply voltage range. Its sleek anthracite enclosure offers both surface and flush mounting options.
The RDCV is an ideal solution for modern ventilation needs, combining a user-friendly interface, smart automatic mode, and flexible installation options.
Additional specifications and description
EC fan speed controller
The RDCV is intended for EC fan speed regulation. Most EC fans can be controlled using a control signal (0-10 VDC / 0-20 mA / PWM). In the majority of cases, it is controlled with a 0 – 10 V signal. This control signal provides information about the requested fan speed. 0-10 Volt is the default setting of the RDCV. Different types of control signals can be selected.
How Does the RDCV Operate in Manual Mode, and What Are Its Output Settings?
RDCV is a digital potentiometer that generates an analogue output signal. The default output type is 0-10 V. A different output type can be selected via Modbus RTU communication: 0-10 VDC, 0-20 mA or 0-100% PWM. This analogue output signal can be adjusted to be continuously variable or in 2 to 10 steps. Via the up and down arrows, it can be manually adjusted. By pressing the select button with the green check mark for 4 seconds, the potentiometer can be activated or deactivated. The selected output value is visualised via the 7-segment LED display (% or step number).
How Does the Controller Utilize Modbus RTU Communication?
The controller features Modbus RTU communication. As standard, Sentera devices with Modbus RTU on board can be set up using the free 3SModbus software. Modbus RTU holding registers duplicate the functions selected via the keyboard interface. If you choose to make use of this functionality, you will have access to the complete set of features offered by the RDCV using your computer.
How and Where Should the Controller Be Mounted?
The enclosure of the controller allows both surface and flush mounting. When it is built-in a wall, its protection against the ingress of dirt and dust is IP44. For surface mounting, the protection degree is IP54.

The RDCV can be installed on and in all kinds of walls – solid, gypsum board or wooden panels. If you opt for inset installation, the mounting holes fit perfectly the standard European wall boxes used for flush mounting.
