If the VCC-X has a Space Temperature Sensor installed and it has
the Override Button option, the HVAC unit will initiate Override
Mode any time the Override Button is pressed and held for less than
3 seconds. This puts the unit into Occupied operation. The Push-
Button Override Duration Setpoint allows you to adjust the amount
of time the Override will remain in effect when the Override Button
is pressed. To cancel the Override before the Override Duration
time period expires, press the Override Button for 5 to 10 seconds.
