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?

b. What temperature should the building be If you want to change the preprogrammed

at this time? (heating? cooling?)

2a. What time does the building become va-

cant?

b. What temperature should the building be

at this time?

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).

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

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 24VAC power

the lowest cooling setpoint temperature

lowest selected cooling temperature, you

cannot select a heating temperature any

higher than 68°F). If such a conflict exists,

9. Why won’t the system turn on, even

though the thermostat display is func-

10. Why doesn’t the temperature change at
