Operating Features

Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat.

•SIMULTANEOUS HEATING/COOLING PROGRAM STORAGE — When programming, you can enter both your heating and cooling programs at the same time. There is no need to reprogram the thermostat at the beginning of each season.

•TEMPERATURE OVERRIDE — Press or until the display shows the temperature you want. The thermostat will override current programming and keep the room temperature at the selected temperature until the next program period begins. Then the thermostat will automati- cally revert to the program.

•HOLD TEMPERATURE — The thermostat can hold any temperature within its range for an indefinite period, without reverting to the programmed temperature. Press HOLD TEMP button. HOLD will be displayed. Then choose the

desired hold temperature by pressing or . The thermostat will hold the room temperature at the selected setting until you press RUN PRGM button to start program operation again.

•°F/°C CONVERTIBILITY — Press SET TIME and HOLD

TEMP buttons until the temperature display is in Celsius (°C). To display Fahrenheit (°F), repeat the process.

•12-HOUR/24-HOUR CLOCK DISPLAY — The clock is set to display 12-hour time, which means that the clock will display AM and PM time (12:00 AM is midnight; 12:00 PM is noon). However, you may want to display a 24-hour clock (military-style time). The 24-hour clock display will show 1:00 PM as 13:00, 2:00 PM as 14:00, and so on. To change to the 24-hour clock display, press SET TIME and RUN PRGM buttons at the same time. In the 24-hour clock mode, AM and PM are not displayed.

•LOW BATTERY INDICATOR — If the 3 “AA” alkaline batteries are low and should be replaced, the display will be blank except for the word BATTERY. When the batteries are low, pressing any button will cause the display to operate for ten seconds. After ten seconds, the display will be blank except for the word BATTERY. You cannot program with low batteries, but you can override setpoint temperature.

•TEMPERATURE DISPLAY ADJUSTMENT — Your new thermostat has been accurately set in our factory. However, if you wish, you may adjust your new thermostat tempera-

ture display to match your old thermostat. This can be accomplished (within a ±4° range) as follows:

1.Press VIEW PRGM and HOLD TEMP buttons at the same time.

2.Press or to adjust the displayed temperature to your desired setting.

3.Press RUN PRGM to resume normal program operation.

PROGRAMMING YOUR THERMOSTAT

Now you are ready to program your thermostat. This section will help you plan your thermostat’s program to meet your needs. For maximum comfort and efficiency, keep the following guide- lines in mind when planning your program.

•When heating (cooling) your building, program the tem- peratures to be cooler (warmer) when the building is vacant or during periods of low activity.

•During early morning hours, the need for cooling is usually minimal.

•Program the thermostat to allow about 30 minutes to reach the desired temperature. (For example, if the first person gets up at 6:00 AM, program the first period to begin at 5:30 AM.)

Look at the factory preprogrammed times and temperatures shown below. If this program will suit your needs, simply press the RUN PRGM button to begin running the factory preset program.

If you want to change the preprogrammed times and tempera- tures, follow these steps.

Determine the time periods and heating and cooling tempera- tures for your heating and cooling programs. You must program four periods for both the heating and cooling programs. How- ever, you may use the same heating and cooling temperatures for consecutive time periods. Use the table at the bottom of the page to plan your program time periods, and the temperatures you want during each period. You may also want to look at the sample program table to get an idea of how the thermostat can be programmed.
