PROGRAMMING
The keyboard is located behind the thermostat cover. Sixteen keys are used to set, review and modify programmed times and temperature settings.
The thermostat display shows a day, time, program period, and temperature.
The thermostat can be set for two Occupied and two Unoccupied times for each day of the week (28 independent time settings). Temporary Occupied key provides quick temporary temperature changes for increased occupant comfort. The Continuous An unoccupied key provides energy-efficient operation for extended periods of time.
Before starting the program procedure, use the the following chart to organize the program schedule.

| Temperature settings will not change (Example: cannot set the heating higher or the cooling lower). | • Check that the temperature setpoints are:
– heating: 40 to 90°F (7 to 31°C) – cooling: 45 to 99°F (9 to 37°C). • Keyboard is locked. Contact the installer. |
| Heating will not come on. | • Check if the circuit breaker is tripped—reset the circuit breaker.
