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  
of this manual.

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

PROGRAMMINGYOURTHERMOSTAT  
Now you are ready to program your thermostat.  
This section will help you plan and program your  
thermostat to meet your needs.  
PLANNING FOR YOUR NEEDS  
First, answer the following questions to help you  
decide what your needs are. If you are using the  
thermostatforacommercialapplication(astore,  
officebuilding,etc.),answerquestions1through  
4. If you are using the thermostat in your home,  
answer questions 5 through 8.  
For maximum comfort and efficiency, keep the  
following guidelines in mind when planning your  
program.  
• When heating (cooling) your building, pro-  
gramthetemperaturestobecooler(warmer)  
when the building is vacant or during peri-  
ods of low activity.  
FOR COMMERCIAL APPLICATIONS:  
1a. What time does the first person arrive at the  
building in the morning?  
b. What temperature should the building be at  
this time? (heating? cooling?)  
• During early morning hours, the need for  
cooling is usually minimal.  
2a. What time do the building occupants reach

ment, meeting rooms, etc.)?

NOTE  
To operate properly in the AUTO mode, there  
must be a minimum 1°F separation between  
the highest heat temperature and the lowest  
cool temperature (see diagram below).  
1. Determine the heating and cooling tem-  
peratures you want to use. You may select  
up to two heating temperatures (HEAT A  
and HEAT B), and up to two cooling tem-  
peratures (COOL A and COOL B). Use the  
table on the next page to write down the  
temperatures you have selected. Keep in  
mind that you can program up to 4 tempera-  
tures (2 heating, 2 cooling) at a time.

for each day separately (for example, heat-  
ing/cooling period 1 on Monday may begin

GRAMMING YOUR THERMOSTAT.  
4. What happens if the electricity goes off  
or is manually shut off?  
6. What can cause the thermostat display  
to freeze or go blank?  
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  
a cooling temperature of 82°F until you  
reenter your program. Setpoint tempera-  
ture will not be displayed.  
A completely blank display may indicate  
that power has been lost to the thermostat  
and the backup battery is also dead. How-  
ever, if there is power to the thermostat and  
the display is blank or frozen, static dis-  
charge is probably the cause.  
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.  
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.

To correct this, remove the thermostat from 7. Why won’t the setpoint temperature go

about two minutes, then reconnect the bat-

to the temperature I want?  
The highest heating setpoint temperature  
you select must be at least 1°F lower than  
thelowestcoolingsetpointtemperatureyou  
select (for example, if 70°F is your lowest  
selected cooling temperature, you cannot  
select a heating temperature any higher  
than 69°F). If such a conflict exists, you  
must set the lowest cooling temperature  
higher in order to set the heating tempera-  
ture higher. To set a lower cooling tempera-  
ture, you must select a lower heating tem-  
perature. See PROGRAMMING YOUR
