Internal Schedule Used for Night Setbacks
and Overrides
If this input is reading a temperature sensor which will be using Night
Setbacks or Unoccupied Overrides, select the applicable schedule.
See Figure 14 below. Actual Schedules are set in the Schedules
Window. See instructions on page 35 for setting Schedules.
Type a value between
.1 Hours and 24 Hours
and press
to save.
Figure 15: Override Duration Field
Override Duration
When setting an Override Duration, you must fi rst select the schedule
in the
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.
