Override Duration

When setting an Override Duration, you must fi rst select the schedule
in the <Internal Schedule Used for Night Setbacks & Over-
rides>

fi eld. When either a WattMaster Thermistor Temperature

Sensor or a Communicating Temperature Sensor is used, an Over-
ride Duration can be entered. When the Override Button is pushed
on one of these sensors during the scheduled Unoccupied Mode,
the schedule will be overridden back into the Occupied Mode. The
Override Duration determines the amount of time the schedule will
remain in Override Occupied Mode.

NOTE: If using a Thermistor Sensor, the Override can be

cancelled by pressing the override button for 3 to 10
seconds. If using a Communicating Sensor with an
Override button, pressing the button while in Override
operation will cancel the Override.
