AUTOMATIC VENTILATION setting
The automatic ventilation 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
WKHFRROLQJVHDVRQVXFKDVHDUO\PRUQLQJRUDWQLJKW³%\SDVV´
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.
