Minimum Vent and Purge Settings Menu - continued
The Humidity Purge ON time determines how long the building will purge when triggered by the Humidity Purge
Setpoint and Humidity Delay timer. The Humidity Delay timer is the length of time humidity must be at or above the
Humidity Purge Setpoint before starting a purge based on humidity.
MINIMUM VENT AND PURGE SETTING Z1-S01
Humidity Purge ON: 0:10:00 Delay 1:00:00
VAL-CO®
recommends setting the Humidity Purge Delay slightly longer than the minimum ventilation cycle. The
Humidity Purge ON time should be similar to the Minimum Vent Timer ON. This approach increases the amount of
ventilation the building receives as humidity increases.
If you do not have any fans designated as Purge fans, the menu item shown below is displayed.
