Clock setting
You can program four time periods each day, with different settings for weekdays and weekends. We recommend the pre-set settings (shown in the table below), since they can reduce your heating/cooling expenses.
To adjust program schedules
Program schedule override (temporary)
Press
The new temperature will be maintained until the next time period. When the timer expires, the program schedule will resume and set the temperature to the level you’ve programmed for the current time period.
To cancel the temporary setting at any time, press USE SCHEDULE.
Program schedule override (permanent)
Press
Whatever temperature you set will be maintained 24 hours a day, until you manually change it, or press USE SCHEDULE to cancel “Hold” and resume the program schedule.
Auto changeover
Use this feature in climates where both air conditioning and heating are used on the same day. When the system mode is in Auto, the thermostat automatically selects heating or cooling depending on the indoor temperature.
While in the Auto mode, if a schedule override takes place (temporarily or permanently) the thermostat will automatically adjust the cooling and heating settings to maintain a Tue 3-degree separation between the cool and heat settings.
For example, if the heat temperature is raised to where it gets within 3-degrees of the cool setting, the display will show an up arrow next to “Cool” to show the thermostat is raising the cool setting up to maintain a 3-degree separation. The display will also show both “Auto” and either “Heat” or “Cool” for which temperature setting you are currently adjusting. Press the system button to select between the heat and cool to view/adjust either mode.
CAUTION: To avoid possible compressor damage, do not use Auto Changeover if the outside temperature drops below 50°F (10°C).
If activated during installation, the furnace filter reminder alerts you when it is time to replace your filter.
Press RESET after changing the filter, to restart the timer.
To reset the reminder interval before it expires:
Smart Response® Technology: This feature allows the thermostat to “learn” how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the time you set. For example: Set the Wake time to 6 am, and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6. The message “Recovery” is displayed when the system is activated before a scheduled time period. Compressor Protection: This feature forces the compressor to wait a few minutes before restarting, to prevent equipment damage. During the wait time, the message “Wait” is displayed on screen.
Auto Changeover: This feature is used in climates where both air conditioning and heating are used on the same day. When the system is set to Auto, the thermostat automatically selects heating or cooling depending on the indoor temperature. Heat and cool settings must be at least 3 degrees apart. The thermostat will automatically adjust settings to maintain this 3-degree separation.
Batteries are optional (to provide backup power) if your thermostat was wired to run on AC power when installed. Install fresh batteries immediately when the LO BATT warning begins flashing. The warning flashes about 30 days before batteries are depleted. Even if the warning does not appear, you should replace batteries once a year, or before leaving home for more than a month.
If you have difficulty with your thermostat, please try the following suggestions. Most problems can be corrected quickly and easily.
