VAV VV550 Controller Device Home Tabs: Instructions
Occupied Bypass Timer: Type the amount of time that the controller remains in the occupied
bypass mode. If the controller is in the unoccupied mode and an occupant presses the On button
at the zone sensor, the controller goes into occupied bypass mode for this amount of time.
Power-up Control Wait: Type the number of seconds you want the controller to wait after startup
before starting normal operation. When power-up control wait is enabled (whenever a time is
entered here), the controller remains off until one of two conditions occurs:
• Controller receives communicated information on the Comm5 link
• Power-up control wait time expires
Note: If auto calibration is enabled, the controller will calibrate during power-up control wait.

If you do not release the overrides here, the controller automatically releases them after 10 hours
by default for air valves and water valves. You can change this default in the Timers area on the
Other tab in the Configuration dialog box. The controller does not automatically release fan
overrides.
