2 models:
  • RMEC VD 230V: supplied with 230V mono - Communicating Modbus RTU.
  • RMEC VD 230V SIGFOX: supplied with 230V mono - Communicating Modbus RTU or Sigfox. : see IoT connected products

main box
  • Servo-control or regulation operation:
    • Flow control to an external sensor (temperature / hygrometry / CO2 / VOC…) or to a manual request by remote potentiometer.
    • Automatic regulation of pressure or flow to the set point value. Entry of the K coefficient (QV=K√ΔP) for display and regulation of the flow.
  • Integrated PID controller and pressure sensors.
  • Backlit LCD display + function keys on the front. Clear display of the measurement (pressure/flow/CO2, etc.) and the set point set.
  • Weekly clock for automatic operation management. Automatic change of the day/night set point value, or of the operating mode.
  • Integrated post-ventilation function (case of use of an electric heater on the supply network).
  • Alarm detection with report of information on dry contact: filter clogging, fan fault, loss of sensor signal.
Accessory remote control
  • IP21 remote control with backlit LCD display for setting/controlling the system, copying to 100% information from the RMEC or RMEC SIGFOX display.
  • 1m long cable supplied for temporary use of the remote control by quick connection to the jack socket on the front of the main box: ideal for starting up when the fan is installed in a small space (false ceiling, etc.).
  • Permanent use of the remote control by dedicated input on the terminal block of the main unit (surface or recessed mounting possible).


Communicating ModBus RTU as standard.

  • SIGFOX network, very low speed and very long range cellular wireless network with national coverage.
  • Allows VMC installation supervision (collective or tertiary).
  • Economical alternative technology to wired / 3G solutions for monitoring or remote reading.
  • Additional card integrated into the RMEC to upload data on the SIGFOX radio network (antenna supplied):
    • Measurement of pressure and flow every hour,
    • Transmission once a day at a fixed time (average over 24 hours) of the pressure and flow rate of the installation (average, mini and maxi values),
    • Alarm on pressure and minimum flow threshold,
    • Alarm in the event of power failure / return.
  • NFC tag for complete identification of the RMEC SIGFOX (product number, serial number, manufacturing batch number).
