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.

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.

• COMPUTED ENERGY MANAGEMENT

RECOVERY (EMR) — The thermostat’s

microcomputerautomaticallycalculatesthe

the next program setting. Then the thermo-

stat will activate the heating or cooling sys-

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

62°F, and that during the next program

AUTO mode). The system will now auto-

matically switch between heating and cool-

ing depending on the actual room tempera-

ture.

The thermostat will not allow the tempera-

ture separation between the highest heat

setting and the lowest cool setting to be less

that 1°F. For example, if the highest heat

setting is 76°F, the lowest cool setting can-

not be below 77°F (see diagram below).

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

answer questions 5 through 8.

For maximum comfort and efficiency, keep the

following guidelines in mind when planning your

ods of low activity.

FOR COMMERCIAL APPLICATIONS:

• During early morning hours, the need for

cooling is usually minimal.

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.

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

the wall and disconnect the battery. Wait

about two minutes, then reconnect the bat-

tery. Thethermostatwillreverttothefactory

thermostat. If you don’t want to reprogram

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

build-up before touching the thermostat.
