the programming examples section lists these factory settings. If the times and temperatures are the same as your schedule, you may simply run the factory installed program by pressing PROGRAM RUN .

Compressor Short-Cycle Protection.

Your thermostat is designed to protect your system against premature compressor failure by “locking out” the compressor. This ensures that the compressor will stay off for approximately five minutes between cycles. When the thermo- stat is in compressor lock-out, the word COOL will flash. During this period, the compressor will not be energized.

Programmable Fan Control.

This feature allows you to have your fan operate continuously through one or more programmed time periods. This is useful if you want to have constant air circulation during a specific time period. If you do not use this feature, the fan will cycle normally with the heating and cooling system.

To program the fan, follow the steps in the PROGRAMMING section. In each time period, you can press the FAN key to select a continuous fan or a normally cycling fan. The display will show PRG FAN ON when continuous fan is selected. This means at the time you set the period to start, the fan will come on and run continuously until the next

program time period.

Example: Your thermostat is programmed with the original factory settings for the Monday MOR period in the heating mode.

Pressing PROGRAM VIEW will display MOR, 6AM and 70. Pressing the FAN key will toggle the programmable fan ON and a second press would turn it back OFF. When PRG FAN ON is in the upper right of the display, your thermostat is programmed to adjust the temperature to 70° at 6AM and also bring the fan on to run constantly until the next program time period.

At the next time period you may choose to continue the program fan
