SENSOR OR SIMILAR
UVF-ECOWATT units are equipped with EC motors. In all of them there are specifi c terminals to
receive a motor speed regulation signal (0-10V).
The 0V signal corresponds to the stop of the fan, while the 10V signal corresponds to the maximum
speed of the fan. By connecting an AIRSENS CO2 air quality sensor it is possible to regulate the fan
proportionally.

If, in addition to speed regulation, it is needed to control the fouling status of the fi lters, carry out
a time programming or have Modbus communication, you will need to use a CONTROL CAD-REG
control accessory.
