Choose the Fan Setting (Auto or On)

Fan Auto is the most commonly selected setting and runs the fan only when the heating or cooling system is on.

Fan On selection runs the fan continuously for increased air circulation or to allow additional air cleaning.

Fan Prog On indicates that the fan is programmed to be on for the entire period. The Prog Fan On can be overridden to have the fan cycle with the system. Press the FAN but- ton to change the fan to Auto. The fan programming will be overridden until the next program period begins or until Run Schedule is pressed.

Choose the System Setting

(Cool, Off, Heat, Auto)

Press the SYSTEM button to select:

Heat: Thermostat controls only the heating system.

Off: Heating and Cooling systems are off.

Cool: Thermostat controls only the cooling system.

Auto: Auto Changeover is used in areas where both heating and cooling may be required on the same day. AUTO allows the thermostat to automatically select heating or cooling depending on the indoor temperature and the selected heat and cool temperatures. When using AUTO, be sure to set the Cooling temperatures more than 1° Fahrenheit higher than the heating temperature.

Manual Operation for

Non-Programmable Mode

Press the SYSTEM button to select Heat or Cool and use the buttons to adjust the temperature to your desired setting. After selecting your desired settings you can also press the SYSTEM button to select AUTO to allow the thermostat to automatically change between Heat and Cool.

Manual Operation (Bypassing the Program) Programmable Mode

Adjust the temperature wherever you like and then press the HOLD button. This will override the program. The HOLD feature bypasses the program and allows you to adjust the temperature manually, as needed. Whatever temperature you set in HOLD will be maintained 24 hours a day, until you manually change the temperature or press Run Schedule to cancel HOLD and resume the programmed schedule.

Program Override (Temporary Override)

Press buttons to adjust the temperature. This will override the temperature setting for a two hour override period.

Example: If you turn up the heat during the morning program, it will be automatically lowered later, when the temporary hold period ends. To cancel the temporary setting at any time and return to the program, press Run Schedule.

If the SYSTEM button is pressed to select AUTO the thermostat will change to Heat or Cool, whichever ran last. If it switches to heat, but you want cool, or it changes to cool, but you want heat, press both buttons simultaneously to change to the other mode.
