This thermostat is ready to go!
Your new thermostat is pre-programmed and ready to go.
See page 3 to check settings.
Congratulations! You’ve just purchased the world’s most advanced, easy-to-use thermostat. It has been designed to give you many years of reliable service and climate control.
Your new thermostat is pre-programmed and ready to go. All you have to do is set the time and day. Then check the settings below and change if needed:
Arrow buttons
Quick reference to status display
Clock setting
Fan setting
Press SYSTEM & FAN, then FAN to select fan operation:
Follow steps at left to select system:
It’s easy to program your system for maximum energy savings. You can program four time periods each day, with different settings for weekdays and weekends.
Energy saving settings for maximum cost savings
This thermostat is pre-set with energy saving program settings. We recommend these settings, since they can reduce your heating/cooling expenses. (See next page to adjust times and temperatures of each time period.)
Program schedule override (temporary)
Program schedule override (permanent)
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 3-degree separation between the cool and heat settings.
For example, if the heat temperature is raised to where it gets within 3-dgrees 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-dgreee 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.
If the cool temperature is lowered to where it gets close to the heat setting, an arrow next to heat will show the thermostat is lowering the heat setting down to maintain a 3-degree separation.
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.
