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.

PROGRAMMING YOUR THERMOSTAT  
Nowyouarereadytoprogramyourthermostat.  
This section will help you plan and program  
your thermostat to meet your needs. For maxi-  
mumcomfortandefficiency, keepthefollowing  
guidelines in mind when planning your pro-  
gram.  
• During early morning hours, the need for  
cooling is usually minimal.  
PLANNING FOR YOUR NEEDS  
First, answer the following questions to help  
you decide what your needs are.  
• When heating (cooling) your building, pro-  
gram the temperatures to be cooler  
(warmer) when the building is vacant or  
during periods of low activity.  
1a. What time does the first person arrive at  
the building in the morning?

times and temperatures, do the following.  
Determine the heating and cooling times and  
temperatures you want to use. Use the follow-  
ing table to plan your program time periods and  
temperatures. You may also want to look at the  
sample program table to get an idea of how the  
thermostat can be programmed. You may se-  
lect up to two heating temperatures (HEAT O  
for occupied temperature and HEAT U for  
unoccupied temperature), and up to two cool-  
ing temperatures (COOL O and COOL U).

electricity is restored, the thermostat will

The highest heating setpoint temperature

lowest selected cooling temperature, you  
cannot select a heating temperature any
