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 and hold SET TIME and
HOLD TEMP buttons until the temperature display is in Celsius (°C). To display Fahrenheit (°F), repeat the pro- cess.
•
•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.
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 weekday and weekend programs. You must program four periods for both the weekday and weekend pro- gram. However, you may use the same heating and cooling temperatures for consecutive time periods. You can choose start times, heating temperatures, and cooling temperatures independently for both weekday and weekend programs (for example, you may select 5:00 AM and 70° as the weekday 1st period heating start time and temperature, and also choose 7:00 AM and 76° as the weekday 1st period cooling start time and temperature).

*We suggest that you program the thermostat so that the heating/cooling system has 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).
