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 9797 Reavis Road, St.

provides power to the thermostat when

long enough for the program to be lost,

the thermostat will automatically return to

To operate properly in the AUTO mode, there

1. Determine the heating and cooling tem-

up to two heating temperatures (HEAT A

and HEAT B), and up to two cooling tem-

peratures (COOL A and COOL B). Use the

following table to write down the tempera-

The thermostat can only be programmed in

the HEAT and COOL modes. See PRO-

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

maintainaheatingtemperatureof64°Fand

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.

If a fresh 9 volt Energizer^®alkaline battery

is installed, the program will be maintained

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.

Tocorrectthis, removethethermostatfrom

the wall and disconnect the battery. Wait

about two minutes, then reconnect the bat-

tery. The thermostat will revert to the fac-

torypresetprogramuntilyoureprogramthe

To prevent further static discharge prob-

lems, touch another object to release static

build-up before touching the thermostat.

See OPERATING YOUR THERMOSTAT.

7. 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

the lowest cooling setpoint temperature

you select (for example, if 70°F is your

lowest selected cooling temperature, you

cannot select a heating temperature any

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

you must set the lowest cooling tempera-

ture higher in order to set the heating tem-

perature higher. To set a lower cooling

temperature, you must select a lower heat-

ing temperature. See PROGRAMMING

YOUR THERMOSTAT.

8. Why doesn’t the display light come on

when I press a button? Why don’t I hear

a beep when I press a button?

Either the compressor lockout feature is in

operation or the thermostat is not currently

calling for heat or cool. Wait about 5 min-

utes for the compressor lockout to expire. If

the system is still not running, read the

cautionary statement below. If conditions

10. Why won’t the system turn on, even

though the thermostat display is func-

11. Why doesn’t the temperature change at

the time I programmed?

• You have programmed the incorrect day

or time. Check your programming (be

sure that the times you programmed are

correct AM or PM times). See PRO-

GRAMMING YOUR THERMOSTAT.

There may be a number of causes for this

situation. The following are primary rea-

sons.

• The thermostat is in the HOLD mode.

• TheEMRfunctionisoperating.TheEMR

function will automatically bring on the

system automatically to bring the tem-

perature to the selected level by the

beginning of the next program period.

frequently (seldom)?

• You have programmed the fan to run

continuously during this period. See

PROGRAMMING YOUR THERMO-

STAT.

Theanticipationsettingistoolow(high). To

change anticipation settings, see OPER-

• The blower delay feature is operating.

This energy saving feature continues to

blow conditioned air through the ducts

after the system has turned off, rather

than letting the air dissipate.
