If the working temperature falls below the Purge Inhibit Temp LOW setting, purging is inhibited (or stopped if a purge
is in progress). If the temperature rises above the Purge Inhibit Temp HIGH setting, purging is inhibited (or stopped if
a purge is in progress).
MINIMUM VENT AND PURGE SETTING Z1-S01
Purge Inhibit Temp LOW: 60.0 HIGH: 95.0
The minimum ventilation and the humidity purge cannot occur simultaneously. When a purge
cycle completes, the controller resets the minimum ventilation OFF timer so that it needs to
cycle completely before a new purge can start.
We recommend you set your HIGH Purge Inhibit Temp at the point you begin turning on fans based
on temperature.
It is possible to heat the zone before purging. Heated air holds more moisture, causing more moisture to be removed
during purging. You can heat the zone to a maximum of 5 degrees above the Temperature Setpoint. This value will
change with the Temperature Setpoint.
