Mounting Instructions

Each controller is specially designed for easy installation either directly on an air duct or in a panel by using the integrated mounting collar and the screw
that is provided with the controller. This mounting arrangement opposes the torque applied to the damper shaft.
Mounting Position
To prevent condensation on the VAV box's damper shaft from entering the controller's electronics, the controller's mounting orientation should be any
position above the damper shaft (between 0 and 180°) so that any condensation from the damper shaft will fall away from the controller's electronics.
Further countermeasures may be required in some installations. This is important in hot, humid climates where the VAV box is located near exterior
doors or loading bays that may be blocked open or when the VAV box air supply is below 50°F.
