The current day and time are now programmed. The 
preprogrammed schedule is activated. The preprogrammed 
settings can be customized or cleared. When using the 
preprogrammed settings as is, programming is done. To 
customize or create a new program, follow the steps in the 
Setting a Customized Program section. Operating the Comfort 
Center™ section shows how to make any temporary changes.

Setting a Customized Program 

Planning your Program

Plan a schedule before programming. Leave any period blank 
when no setting is required. When an outdoor sensor is part of 
the system, enter a frost setting. The humidity and frost 
settings are the same for the entire program.

Programming the First Day

When changing the existing program, go to step 7a. When 
clearing the program and starting over, proceed as follows. 

NOTE:

Press the RUN key at any time to exit the 
programming mode.

1. Clearing Current Program

a. Press SELECT PERIOD.

b. Hold CANCEL until display shows 

PROG CLR.

2. Setting Day, Time, and Setpoints

a. Press SELECT PERIOD until display shows 

WAKE. 

b. Press DAY until display shows 

MON. 

c. When display reads 

COOL SET PT, press HEAT/

COOL SETPOINTS to switch to 

HEAT SET PT. 

d. Press and hold a TIME key until the display shows 

the desired starting time. The time changes in ten-
minute increments. 

e. Press and hold the up or down arrowhead key until 

the display shows the desired temperature. 

f.

Press HEAT/COOL SETPOINTS to switch to 

COOL 

SET PT. 

NOTE:

The time is used for both heating and cooling. 
When you change the time while setting the 
cooling temperatures, the time is also changed 
for heating.

g. Press and hold the up or down arrowhead key until 

the display shows the desired temperature. 

NOTES:
— When the numbers do not move while you are 

holding the up or down arrowhead key, the setting 
limit (45°F and 88°F) is reached.

— When set for auto changeover, there must be 3°F 

between the heating and cooling setpoints. When 
setting the cooling setpoint with the heating setpoint 
at 68°, the cooling setpoint can be no lower than 71°. 
And when cooling is set for 70°, the heat setpoint 
changes to 67°. The PC8900A automatically pushes 
the alternate setpoint so you can adjust the setpoint 
to its desired setting.

— When set for manual changeover, the 3° differential 

between the heating and cooling setpoint does not 
apply.

3. Setting Fan

IMPORTANT

The FAN and VENTILATOR settings are the same for 
heating and cooling. The FAN setting for heating 
cannot be set for AUTO and the cooling set for CIRC.

a. Press FAN until 

FAN AUTO, FAN ON or FAN CIRC 

is displayed, as desired. 

NOTES:
— AUTO means the fan only runs when heating or 

cooling is running.

— ON means the fan runs during this entire period. 
— CIRC means the fan runs at least 30 percent of the 

time during this period, including when the heating or 
cooling system is running.
