Note: The Setback/Off switch setting must be in the Setback position in order to have access to the SCHEDULE menu.
Setting the Schedule
A schedule allows the control to automatically change between the Occupied and Unoccupied temperature settings based
on the time of day.
A two-event schedule divides the day into Occupied and Unoccupied time periods. A four-event schedule divides the day
into Occupied 1, Unoccupied 1, Occupied 2, and Unoccupied 2 time periods.
To set the time of day at which each period is to begin, use the following procedure.
The control has a built-in test routine that is used to test the main control functions. The control
continually monitors the sensors and displays an error message whenever a fault is found. See
the following pages for a list of the control’s error messages and possible causes. When the
Test button is pressed, the Test light is turned on. The individual outputs and relays are tested
in the following test sequence.
