Data Sheet for Product

Relief Fan
The Predator supports operation of a two-state relief device: fan or damper. When the supply
fan is on and the OA damper opens beyond a selected range, the relief device is activated.
High Speed Fan Setting
The controller may operate a separate output to run the supply fan at high speed. This is
applied whenever the unit starts in the unoccupied mode. It is also applied for the first few
seconds of occupancy.
Demand Control Ventilation (DCV)
During occupied mode, the outdoor air damper opens to the design ventilation setting and
stays open. The controller supports demand-controlled ventilation by allowing another node to
dynamically adjust the minimum ventilation setting.
