By default, this thermostat has 4 separate program periods for both Heat and

Cool mode, they are: MORN, DAY, EVE, and NITE. Each period ends at the start

time of the following period. The heat programs are set in HEAT mode, and the

cool programs are set in COOL mode.

NOTE: If the thermostat is configured to use only 2 periods per day instead of 4

(SYSTEM CONFIGURATION AND SETUP OPTIONS), the thermostat will only use the

DAY and NITE periods. The MORN and EVE periods will not be visible on the

screen.

SET TEMPERATURE PROGRAMS: Move the Set Slide switch to the TEMP PROG

position. Programming will start with all 5 weekdays, Monday through Friday (all

grouped together). Use the UP/DOWN buttons to adjust the start time for the

MORN period, then press the NEXT button to advance. Use the UP/DOWN buttons

to adjust the set temperature for the MORN period, then press the NEXT button to

advance. Now adjust the start time and set temperature for the DAY period,

pressing the NEXT button after each to advance. Continue with these same steps

to adjust the start times and set temperatures for the EVE and NITE program

periods.

When the NITE period is finished for the weekdays, the thermostat will advance

forward to the weekend program, with the MORN period start time flashing. You

will be setting the program periods for both Saturday and Sunday (grouped

together). Perform the same steps that you used for setting the weekday

periods, pressing the NEXT button to advance through each flashing value.

Return the Set Slide switch to the RUN position when you are finished.
