To set the rotational limits, do the following
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.
Mounting on a VAV terminal box
Mount the controller inside of a metal enclosure. To maintain RF emissions specifications,
use either shielded connecting cables or enclose all cables in conduit.
Mount the controller directly over the damper shaft. A minimum shaft length of 2.0 inch
(51mm) is required.
Note: SimplyVAV controllers are designed to directly mount to 3/8 to 5/8inch (9.5to16mm)
round or 3/8 to 7/16 inch (9.5to11 mm) square damper shafts.
