The REG System can manage controlled mechanical ventilation (CMV) units both via timetable and via VOC sensor and via a combination of both.
...
VOC sensor (code REG-AQ-Sxx) must be configured with the address from 8A to 8F (as indicated in the product data sheet) without set (s/set) as it has no display and associated with a dedicated zone for renewal within the Zones – Configuration Zone/1 page; furthermore, the ventilation unit must be associated as integration unit:

This special zone manages temperature and humidity in different way:
In temperature there are the ppm (parts per million) of CO2, so if you read 40 that’s 400 ppm.
In humidity you can see the VOC parameters in ppb (parts per billion), then if you read 30 that’s 300 ppb of VOC.
The humidity set point is the hysteresis (multiplied by a factor of 10) of threshold switching between Economy/OFF and Comfort/Economy
Comfort and Economy set point are thresholds, so if I exceed the Economy threshold the CMV starts at Economy speed, if i exceed Comfort it starts in Comfort, to switch to lower speed it must drop below the threshold – the hysteresis.

So, it is the ppm variation in CO2 that activates the Economy and Comfort speed above the thresholds and switches the speed back to OFF and Economy if the value drops below the threshold – the hysteresis:PHOTO TBD
...
The economy and comfort speeds are switched to the Dehumidifier page according to what is indicated in the integration column of the zone which has an associated VOC sensor (on the Zone – Configuration/1 page).
