OCC. BYPASS BUTTON (C7110C1080, ONLY)

AND CALIBRATION LED

The functionality of the occupancy bypass button
(C7110C1080, only) and the corresponding behavior of the
calibration LED are dependent upon the programming of the
connected controller. Please refer to the controller's technical
literature and/or application.
