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.
