Supply Fan Compensation
The outdoor air damper minimum position is modulated to provide outdoor air based on the supply fan
speed. When the supply fan increases speed, the outdoor air damper minimum position is reduced to
prevent over-ventilation. When the supply fan decreases speed the outdoor air damper minimum position is increased to maintain design outdoor air requirements. There are three user-editable design
minimum settings to linearize the damper position with the fan curve during Occupied and Occupied Bypass modes of operation.
- Design Minimum OA Damper Position at Min Fan Capacity (25% default)
- Design Minimum OA Damper Position at Mid Fan Capacity (15% default)
- Design Minimum OA Damper Position at Full Fan Capacity (10% default)
There are three additional user-editable design minimum settings for the Occupied-Standby mode of operation.
- Standby Minimum OA Damper Position at Min Fan Capacity (25% default)
- Standby Minimum OA Damper Position at Mid Fan Capacity (15% default)
- Standby Minimum OA Damper Position at Full Fan Capacity (10% default)
