How to Update Your Thermostat

As seasons change in the Ozarks, we often get people asking about their thermostat settings. The system setting options vary based on your heating and/or cooling type, but these instructions (from our Lennox Elite Touchscreen) can be used to guide you in your thermostat settings.

Lennox ThermostatHEAT −− Thermostat controls heating system.
OFF −− Both heating and cooling systems are off.
COOL −− Thermostat controls cooling system.
AUTO −− The thermostat switches the system from the heating mode to the cooling mode based on temperature.
EM HEAT −− Heat pump systems only −− Thermostat controls emergency heat and auxiliary heat, if needed.
ON −− Fan runs continuously. Use this setting for improved air circulation or for more efficient central air cleaning.
AUTO −− Fan runs only when heating or cooling system is on.
CIRC −− Fan runs randomly approximately 35% of the time. Use this setting for improved air circulation or for more efficient central air cleaning when you do not want the fan to run continuously

Program Your Heating and Cooling Schedule
Many thermostats can control up to four different schedule periods per day:
Wake −− Time when you awaken and want your home at a
comfortable temperature.
Leave −− Time when you leave the home and prefer an energy−saving
temperature setting.
Return −− Time when you return home and want your home to return to a more comfortable temperature setting.
Sleep −− Time when you are asleep and prefer an energy−saving temperature setting.
NOTE − Schedule times are in 15−minute intervals.

1 − Press the SCHED key. The SCHEDULE screen will be displayed.
2 − Press the EDIT key. The screen will change to display the days of the week across the top.
3 − Select any combination of days to edit. You may select multiple days. These should be days that you wish to follow the same schedule. Check marks appear next to the days that are selected. After the first day is selected, the SCHEDULE
screen returns to the display.
4 − Press the WAKE key. The WAKE key will flash to show it is selected.
5 − Press the UP and DOWN keys to modify time and heat and cool temperatures shown on the screen.
6 − Press LEAVE key and repeat step 5.
7 − Press RETURN key and repeat step 5.
8 − Press SLEEP key and repeat step 5.
NOTE − The FAN setting can be programmed for ON, AUTO or CIRC for each period selected. See following page for more information about fan setting options.
9 − Press DONE key when finished. Saving changes screen appears to indicate that schedule changes are being saved to the days selected.
10 − Repeat steps 1 through 9 to set a program schedule for the remaining days of the week. Example: If Mon − Fri was selected first, repeat steps 1 through 9 to program Sat and Sun.
To exit the schedule without saving changes, press CANCEL key at any time.
