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

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.

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.

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

selected temperature for two hours. After

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).

NOTE

This feature will not work in the AUTO mode.

Therefore, we do not recommend using the

PROGRAMMINGYOURTHERMOSTAT

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?

Now look at the factory preprogrammed times thermostatcanbeprogrammed.Youmayselect

2. How can I finish my programming if the

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

to the time/temperature mode. To resume

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

6. Why won’t the setpoint temperature go

to the temperature I want?

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

than 69°F). If such a conflict exists, you

DO NOT use the button to move the

damage may result due to compressor

operation in cold weather.

The 9 volt battery installed in the thermostat

is low and should be replaced with a fresh 9

ATING YOUR THERMOSTAT.

9. Why won’t the system turn on, even

though the thermostat display is func-

tioning normally?

10. Why doesn’t the temperature change at
