Air Treatment Equipment
The CO sensor controls airflow rate so that it best matches the changes of CO
2
This prevents energy losses from over-ventilation while maintaining indoor air quality with optional
CO sensor.

Automatic Ventilation Mode Swithching (Bypass control) with Humidity sensor
Suitable ventilation mode depending on condition will be switched automatically
The ventilation unit detects room temperature and outside air temperature, then automatically switches to suitable ventilation mode to provide
higher energy-saving. By installing humidity sensor (optional item), the mode will be switched automatically based on the amoun t of heat
(energy) and discomfort index to further improve energy saving and comfort. *1
