The unit can be equipped with a VOC (volatile organic compounds) sensor, a humidity sensor
CO₂ sensor
(RH %) and/or a CO₂ sensor.
These sensors provide a continuous quality control of the indoor air and adjust the airflow
accordingly, which results in sufficient ventilation with the lowest possible electrical power
consumption. This operating mode is called demand-controlled mode. If an HRC remote con-
trol is connected, the level is indicated on the display with the level 3 symbol.
A demand-controlled operation ensures the desired ventilation performance with the lowest
possible power consumption.
