Setting the
rotation limits
Before mounting the controller, set the rotation limits with the supplied stop
screw. Installing the stop screw limits the shaft rotation to either 45 or 60 degrees.
Caution
Before setting the rotation limits on the controller, refer to the damper position
specifications in the VAV control box to which the controller will be attached.
Setting rotation limits that do not match the VAV damper may result in
improper operation or equipment damage.
To set the rotational limits:
1. Turn the controller over so you have access to the back.
2. Manually rotate the actuator fully clockwise as viewed from the back.
3. Remove the stop screw from its storage location and clean any debris from
the threads.
4. Insert the screw into the correct stop position hole.
5. Tighten the screw only until the head touches the plastic in the bottom of
the recess.
