About Your New Thermostat . . .  
Your new White-Rodgers Digital Thermostat uses the technology of a solid-state microcomputer  
to provide precise time/temperature control. This thermostat offers you the flexibility to design  
heating and cooling programs that fit your needs.  
Please read this manual thoroughly before operating or programming your thermostat. If you have  
questions, write to us at the address shown on the back cover of this manual.

Turn the thermostat body over. On the back are  
the 3 “AA” Energizer® alkaline batteries.  
The “AA” Energizer® alkaline batteries provide  
powertothethermostatwhenthe24VACpower  
is interrupted (for example, when you remove  
the thermostat from the wall for programming).  
Fresh batteries will maintain the stored program  
for approximately a year. If power loss is long  
enough for the program to be lost, the thermo-  
stat will automatically return to the factory pro-

OPERATING FEATURES  
Now that you are familiar with the thermostat  
display and buttons, read the following informa-  
tion to learn about the many features of the  
thermostat.  
The thermostat is configured at the factory  
so that this feature is disabled. If you wish to  
have this feature, refer to the installation  
instructions for this thermostat, or contact  
your local heating/cooling contractor.  
COMPUTED ENERGY MANAGEMENT  
RECOVERY (EMR) — The thermostat’s  
microcomputer can be set to automatically  
calculate the time it will take to change the  
temperature to the next program setting.  
Then the thermostat will activate the heat-  
ing or cooling system to change the tem-  
perature so that the desired temperature is  
reached at the beginning of the next pro-  
gram period. As an example of this feature,  
assume that you have programmed your  
thermostat to provide an overnight heating  
temperature of 62°F, and that during the  
next program period, beginning at 6:00 AM,

period 1 for Monday will also begin at 5:00

You may only program heating temperatures you have selected  
into the heating program and cooling temperatures into the  
cooling program (for example, you cannot program the COOL A  
temperature into your heating program). You may program the  
temperatures you choose in any order, and you may use the  
same temperature in consecutive program periods (for example,  
you may program period 1 with temperature B and periods 2, 3,  
and 4 with temperature A). You do not have to use all possible  
temperature choices (for example, you may want to select  
temperatures for HEAT A and HEAT B only – in this case, the

6. What can cause the thermostat display  
to freeze or go blank?  
A completely blank display may indicate  
that power has been lost to the thermostat  
and the backup batteries are also dead.  
However, if there is power to the thermostat

you may reprogram the thermostat, then  
replace it on the wall.  
During periods of low humidity (especially  
during cold weather), you may feel or see a  
spark discharge when you touch the ther-  
mostat. This may cause the program to be  
lost or the thermostat to display incorrectly.  
To correct this, remove the thermostat from  
the wall and disconnect the batteries. Wait  
about two minutes, then reconnect the bat-  
teries. The thermostat will revert to the fac-  
tory preset program until you reprogram the  
thermostat. If you don’t want to reprogram

10. Why won’t the compressor turn on, even
