■ AUTOMATIC VENTILATION setting
The automatic damper mode automatically provides the correct
ventilation for the conditions in the room. The following shows the
effect "By-pass" ventilation will have under various conditions.
1. Reduces cooling load
If the air outside is cooler than the air inside the building during the
cooling season (such as early morning or at night), "By-pass"
ventilation will draw in the cooler outside air and reduce the cooling
load on the system.
2. Night purge
"By-pass" ventilation can be used to release hot air from inside the
building that has accumulated in buildings a business district during
the hot summer season.

3. Office equipment room cooling
During cold season, fresh air can be drawn in and used as is to cool
rooms where the temperature has risen due to the use of office
equipment.
Return air

slightly rises more than the outside air temperature because
of the heat effect around the ducts or the unit motors.
