1 The occupied bypass time is used for timed override applications when a building automation system is not present or when the
building automation system does not send the occupied (override) request. The timed override timer is maintained in the unit
controller. When the timed override is applicable, the controller reports Occupied Bypass as its effective occupancy mode.
2 Amount of time a variable-air-volume unit will delay electric heat operation on a transition from occupied to daytime warm-up
operation.

1 Duct Static Pressure Failure, Duct Static Pressure High Limit, Space Temperature Failure, Discharge Air Temperature Failure, Unit
Shutdown, Low Temperature Detect, and Low Supply Fan Air Flow diagnostics can be configured as a group to be either service
required or critical alarm diagnostics; the diagnostics cannot be individually configured.
2 Alarm message text that will be communicated to the building automation system.

1 These set-up parameters are required for Tracer AH540/541 to properly stage electric heat when a step controller is connected
to analog output AO3. The controller assumes each stage On and Off voltage threshold matches the step controller setup.
