1.Move the SYSTEM switch to HEAT.

2.Press VIEW PRGM once. MO, the abbreviation for Monday, will be displayed. Also displayed are the currently pro- grammed start time for the 1st heating/cooling period and the currently programmed HEAT 1, 2, 3, or 4 temperature for the 1st heating/cooling period (flashing).

EXAMPLE:

This example display shows that for the 1st Monday heating/ cooling period, the start time is 6:00 AM, and 68° is the programmed temperature (this example reflects factory pre- programming).

3.If the temperature displayed is not the HEAT 1, 2, 3, or 4

temperature you want for Monday’s period 1, press or until the correct temperature is displayed (if you keep press-

ing or , the HEAT 1, 2, 3, and 4 temperatures you previously programmed will be alternately displayed).

4.To change the displayed start time to the time you have selected for Monday’s heating/cooling period 1, press SET TIME/SET TEMP once (the programmed time will flash).

Press or until your selected time is displayed. The time will change in 30-minute increments. The time that you program will be the start time of Monday’s period 1 for both heating and cooling. After selecting the correct period 1 start time, press SET TIME/SET TEMP again to return to the change temperature mode.

5.Press VIEW PRGM once. The currently programmed start time and heating setpoint temperature for Monday’s heating/ cooling period 2 will be displayed.

6.Repeat steps 3 and 4 to select the start time and heating temperature for Monday’s 2nd heating/cooling period.

7.Repeat steps 3 through 5 for Monday’s 3rd and 4th heating/ cooling period. Monday’s heating program is now complete.

NOTE

If you are programming your thermostat for the first time, and you want programming for all days of the week to be the same as Monday’s program, press RUN PRGM at this point, and proceed to the SELECT COOLING TEMPERATURES section (this COPY DAY feature only works the first time you program your thermostat; if you are changing your thermostat’s programming, you must program each day separately).

8.Press HOLD TEMP/ADV DAY once. TU (indicating Tuesday’s program) will be displayed, along with the start time for the 1st heating/cooling period and the currently programmed heating setpoint temperature.

9.Repeat steps 3 through 7 to complete Tuesday’s heating program.

10.Continue entering each day’s programming until all heating/ cooling periods and heating temperatures have been se- lected.

11.Press RUN PRGM to end heating programming. Proceed to the SELECT COOLING TEMPERATURES section.

1.Move the SYSTEM switch to COOL.

2.Press SET TIME/SET TEMP four times. The display will show the number 1, along with the currently programmed COOL 1 temperature.

3.Press or to change the displayed temperature to your selected COOL 1 setting (if you only want to program a temperature for COOL 1, skip to step 7).

4.Press SET TIME/SET TEMP once. The number 1 will change to the number 2, representing COOL 2.

5.Press or until you reach your selected COOL 2 temperature.

6.Repeat steps 4 and 5 to select COOL 3 and COOL 4 temperature settings, if desired.

7.Press RUN PRGM.

Enter Cooling Temperatures

!CAUTION

If the outside temperature is below 50°F, disconnect power to the cooling system before programming. Energizing the air conditioner compressor during cold weather may cause personal injury or property damage.

1.Move SYSTEM switch to COOL position.

2.Press VIEW PRGM once. MO, the abbreviation for Monday, will be displayed. Also displayed are the start time you previously programmed for the 1st heating/cooling period and the currently programmed COOL 1, 2, 3, or 4 tempera- ture for the 1st heating/cooling period (flashing). Remember that the time you previously selected is for both heating and cooling periods. If you change a programmed start time now, it will also change the start time for the heating program.

3.If the temperature displayed is not the COOL 1, 2, 3, or 4

temperature you want for Monday’s period 1, press or until the correct temperature is displayed (if you keep press-

ing or , the COOL 1, 2, 3, and 4 temperatures you previously programmed will be alternately displayed).

4.Press VIEW PRGM once. The currently programmed start time and cooling setpoint temperature for Monday’s heating/ cooling period 2 will be displayed.

5.Repeat step 3 to select the cooling temperature for Monday’s 2nd heating/cooling period.

6.Repeat steps 3 and 4 for Monday’s 3rd and 4th heating/ cooling period. Monday’s cooling program is now complete.
