Setting the rotation
limits SimplyVAV controllers are manufactured for a damper that rotates 90
degrees from open to close. If the VAV damper is not a 90 degree damper, set
the rotation limits to 45 or 60 degrees before mounting the controller.
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.
