About Your New Thermostat . . .  
Your new Digital COMFORT SET II Multi-stage Thermostat uses the technology of a solid-state  
microcomputer to provide precise time/temperature control. The COMFORT SET II 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, you may write to our Technical Service Department at the address shown on the back  
cover of this booklet.

The Back of The Thermostat Body  
Turn the thermostat body over. On the back are  
the 9 volt Energizer® alkaline battery and the

1. The 9 volt Energizer® alkaline battery pro-  
vides power to the thermostat when the  
24 VAC power is interrupted (for example,  
when you remove the thermostat from the  
wall for programming) A fresh battery will  
maintain the stored program for approxi-  
matelyaweek. Ifpowerlossislongenough  
for the program to be lost, the thermostat  
will automatically return to the factory  
programmed temperatures (64°F heating  
and 82°F cooling) when power is restored.  
You must reprogram the thermostat if this  
happens.

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.  
This feature is enabled by option switch #3.  
To enable the EMR function, you must  
move option switch #3 (located on the back  
of the thermostat body) to the ON position.

tem to change the temperature so that the  
desired temperature is reached at the be-  
ginning of the next program period. As an  
example of this feature, assume that you  
have programmed your thermostat to pro-  
vide an overnight heating temperature of

two hours, the thermostat will automatically  
revert to the program.  
NOTE  
If the thermostat is configured for automatic  
changeover, the thermostat will not allow the  
temperature separation between the highest  
heat setting and the lowest cool setting to be  
less that 1°F. For example, if the highest heat  
settingis76°F, thelowestcoolsettingcannotbe  
below 77°F (see diagram below).

Now you are ready to program your thermostat.  
This section will help you plan and program your  
thermostat to meet your needs. For maximum  
comfortandefficiency,keepthefollowingguide-  
lines in mind when planning your program.  
PLANNING FOR YOUR NEEDS  
First, answer the following questions to help you  
decide what your needs are.  
1a. What time does the first person arrive at the  
building in the morning?  
• When heating (cooling) your building, pro-  
gramthetemperaturestobecooler(warmer)  
when the building is vacant or during peri-  
ods of low activity.  
b. What temperature should the building be at  
this time? (heating? cooling?)  
2a. What time does the building become  
vacant?  
• During early morning hours, the need for  
cooling is usually minimal.  
b. What temperature should the building be at  
this time?

2. How can I finish my programming if the  
display has already changed to time/  
temperature?  
3. What happens if the electricity goes off  
or is manually shut off?  
If you have not installed a 9 volt alkaline  
battery, the display will go blank and the  
program will be lost in five seconds. When  
electricity is restored, the thermostat will  
maintain a heating temperature of 64°F and  
During programming, if no buttons are  
pressed for five minutes, the thermostat will  
enter the HOLD mode and maintain a con-  
stant temperature. The display will change

ever, if there is power to the thermostat and  
the display is blank or frozen, static dis-  
charge is probably the cause.  
If a fresh 9 volt Energizer® alkaline battery is  
installed, the program will be maintained for  
about one week with no 24 VAC power  
present to the thermostat. See OPERAT-  
ING YOUR THERMOSTAT.  
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 battery. Wait  
about two minutes, then re-connect the bat-  
tery. Thethermostatwillreverttothefactory  
preset program until you reprogram the  
thermostat. If you don’t want to reprogram

The highest heating setpoint temperature  
you select must be at least 1°F lower than

select (for example, if 70°F is your lowest  
selected cooling temperature, you cannot  
select a heating temperature any higher
