The keyboard is located behind the thermostat cover with three frequently used keys by the display. The thermostat display shows a day, time, program period, temperature, system, and fan operation selection. The thermostat can be set four times and up to eight temperatures for each day of the week (28 independent times and 56 temperature settings). The s and t keys provide quick temporary temperature changes to increase your comfort. The Hold Temp key provides energy-efficient operation for extended periods of time. Before starting the programming procedure, you can use the following charts to organize your program schedule. The factory preprogrammed time, temperature and fan settings are shown in brackets. If you choose not to program a daytime energy savings period, press the period key (Leave or Return) until the time is blank. The fan setting feature is available on select thermostat models

Setting the Current Day and Time
Programming the First Day
Clearing Program Period
Setting Temporary Temperatures
Changing Temperature Setting Until the Next Program Period
Press the increase or decrease t key until the desired temperature setpoint is displayed
NOTE
If s or t appear under the temperature display, it means that both the heating and cooling setpoints are being adjusted. Tapping the key will change both the heat and cool setpoints by one degree. Press after the desired setpoint is reached to check the setpoints
Changing Temperature Setting Indefinitely
Changing Temperature Setting Until a Designated Day and Period
The system’s default setting is Heat and the fan’s default setting is Auto. Use the System and Fan keys to change the settings. The fan settings can be set for each program period individually. The system selection is for all the program periods. System settings control the thermostat operation as follows: Heat: The thermostat controls the heating. Off: Both the heating and cooling are off. Cool: The thermostat controls the cooling. Auto: The thermostat automatically changes between heating and cooling operations, depending on the indoor temperature (select models).
Fan settings control the system fan as follows:
Setting Temporary Fan Operation
If your thermostat has a Fan key and this feature, press Fan until the desired fan operation is selected. This fan setting will be in effect until the next regularly scheduled period starts.
Viewing and Resetting Timer Settings
When the thermostat activates a timer, the thermostat flashes Filter until the timer resets.
Using Daylight Savings Time Feature
This feature allows you to change in and out of Daylight Savings Time with a key press. When pressed in the fall, the time will go back one hour. In the spring, the time will go ahead one hour and the display will show DST. See the Setting the Current Day and Time section for initial setting instructions.
Displaying the Outdoor Temperature
If your thermostat is equipped with an outdoor sensor, you can check the temperature at the sensor by pressing once.
If you insert new batteries within 20 to 30 seconds of removing the old batteries, the system retains the current time and day. If the display is blank, the batteries are dead or installed incorrectly. You must reset the time and day. Refer to Set the Clock for instructions. As a precaution when leaving home for longer than a month, change batteries before leaving to prevent the system from shutting down due to lack of power. Always use fresh alkaline batteries. Nonalkaline batteries do not last as long. They also can leak, causing damage to the thermostat and the wall surface.
Breakthrough Technology Senses Temperature More As You Do
The Optimum Comfort and Energy Savings Solution
The Deluxe Programmable Thermostat is actually a small but powerful computer. When calculating the time to turn on your heating or cooling system, it considers (1) air temperature, (2) wall temperature, and (3) the time you want the comfort temperature established.
