About Your New Thermostat . . .

Your new Digital COMFORT SET II Multi-stage/Heat Pump 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

programmed a temperature of 70°F. The

thermostat will automatically activate the

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

timeitwilltaketochangethetemperatureto

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

set the thermostat to automatically switch

the system from heating to cooling as

needed. First you must move option switch

thermostat OFF. Then remove the thermo-

stat body from the wall. Check the position

of switch #4 (the last switch on the right). If

it is ON (up), simply put the thermostat back

on the wall. If the switch is OFF (down),

remove the battery, then use a pencil or

small screwdriver to move the switch to the

ON position (see figure at right). Leave the

battery out of the thermostat for at least two

minutes, to allow the thermostat to reset

In the AUTO mode, the thermostat will not

allow the temperature separation between

the highest heat setting and the lowest cool

setting to be less than 1°F. For example, if

the highest heat setting is 76°F, the lowest

cool setting cannot be below 77°F (see

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 remove the battery for at least

two minutes. After reinstalling the battery,

the thermostat will revert to the factory pre-

set program until you reprogram the ther-

mostat. If you don’t want to reprogram the

SYSTEM

to the temperature I want?

In the AUTO mode, the highest heating

setpoint temperature you select must be at

least 1°F lower than the lowest cooling

setpoint temperature you select (for ex-

ample, if 70°F is your lowest selected cool-

ing temperature, you cannot select a heat-

ing temperature any higher than 68°F). If

such a conflict exists, set the lowest cooling

temperature higher in order to set the heat-

ing temperature higher. To set a lower cool-

ing temperature, you must select a lower

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?

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

The display light and audio prompting
