The occupied bypass time which resides in the UC400 controller and defines the duration of the override is configurable from 0 to 240 minutes default value of 120 minutes When the occupied bypass time expires the unit transitions from occupied bypass mode to unoccupied mode Pushing the CANCEL button cancels the timed override request In addition it will end the timed override before the occupied bypass time has expired and transition the unit from occupied bypass mode to unoccupied mode If the controller is in any mode other than unoccupied mode when the ON button is pressed the controller still starts the occupied bypass timer without changing to occupied bypass mode If the controller is placed in unoccupied mode before the occupied bypass timer expires the controller is placed into occupied bypass mode and remains in this mode until either the CANCEL button is pressed on the Trane zone sensor or the occupied bypass time expires Zone Temperature Control The 0 400 controller has three methods of zone temperature control e Cascade zone control used in the occupied occupied bypass and occupied standby modes It maintains zone temperature by controlling the discharge air temperature to control the zone temperature The controller uses the difference between the measured zone temperature and the active zone temperature setpoint to produce a discharge air temperature setpoint The controller compares the discharge air temperature set
