Location Considerations

The LN Compact VAV/VVT controllers are designed for
easy installation. The integrated mounting brackets on
each controller have a diameter of 0.2 in. (5 mm) and
are designed to oppose the shaft torque.
Note: Units with a damper actuator only have one
screw.
To mount the controller:
1. Mount the device directly on an air duct or in a
panel by using the integrated damper brackets and
screws.
2. Remove the terminal blocks, and use the controller
mounting slots to mark the location of any holes to
drill.
3. Remove the device and drill holes.
4. Clean the perforated surface, and fasten the
device using the appropriate screw types.
5. Ensure the damper shaft is at least 1.5 in. (40 mm)
so the damper bracket can fit securely around the
damper shaft. If required, limit the maximum
damper shaft rotation by modifying the position of
the stroke end-stops in 5° increments.
