Remove Old Thermostat

[1 Test to make certain that your heating

and cooling systems are working properly. If

either does not work, contact your local

heating/air conditioning dealer. To avoid

compressor damage, do not operate the

cooling system when outdoor temperature is

below 50° F[10° C].

❑

TURN OFF POWER to system at the

furnace, or at the fuse/circuit breaker panel.

Carefully unpack your new thermostat and

mounting plate; save the package of screws,

instructions and receipt.

URemove cover from old thermostat. If it

does not snap off

when pulled firmly from the

bottom, check for a screw used to lock on the

cover.

Replacing a Clock Thermostat that has C

or Cl Clock Terminals?

If you are replacing a Honeywell

Chronotherm@

Thermostat, you may find one

or two wires that go to the C or Cl clock

terminals on the Chronotherm Thermostat

wiring

wallplate.

Do not allow them to touch,

or you may damage your transformer.

Disconnect the wires and wrap them sepa-

rately, using electrical tape. Do not wrap them

together. Place the wires where they will not

interfere with the operation of the new

thermostat. Record the colors and terminal

designation labels of the remaining wires.

Six or more wires?

If there are six or more wires (excluding

clock wires attached to terminals), you

most likely have a variation of a heat pump

❑

Loosen screws holding thermostat to

subbase,

wallplate

or wall, and lift away.

Disconnect wires from old thermostat or

subbase. As you disconnect each wire, use

masking tape to label it with the old terminal

designation. If there are only two wires, they

do not need to be labeled. If there is an extra

wire that is not connected to your old thermo-

stat, you will

ako

not be connecting it to your

new thermostat. Keep the wires from falling

back into the wall by wrapping them around a

pencil as shown.

or multistage system. The thermostat is

not

compatible with such systems so return

the product to the place of purchase. If you

would like information about which program-

mable thermostats will work with your system,

call Honeywell Customer Assistance at

1-800-468-1502.

Three thermostat wires?

If you have three wires for heating only and

can operate the fan using the fan ON switch,

this thermostat will work with your system.

However, some hot water (zoned) heating

systems have three thermostat wires. The

thermostat will not work without installing an

isolating relay on these systems. For details,

call Honeywell Customer Assistance at 1-800-

468-1502.

Install The Batteries

IMPORTANT:Batteries must be installed for

programming and operation of the thermo-

stat and heating/cooling system.

❑

Purchase two AA alkaline batteries;

non-

alkaline batteries will not last as long, and may

leak, causing damage to thermostat or wall

surface. We recommend Energizer batteries.

•l Make sure the thermostat is set in the OFF

position.

Use a coin to remove battery door.

❑

Install the fresh batteries as shown,

making sure positive and negative terminals

are oriented correctly.

Replace battery door.

flashing. “bAt Lo” will stay on without flashing,

indicating the thermostat and heating/cooling

system have stopped working and the

batteries are almost completely dead.

After the batteries are completely dead, the

“bAt Lo” indicator will disappear, leaving a

completely blank display.

Press down on left ends of batteries to

remove. If you insert the new batteries within

INSTALL TWO AA ALKALINE

/BATTEFIIESASStiOIAIN

E=l

M171

M1779B

As the batteries are running low, a “bAt Lo”

indicator will flash for one to two months

before batteries run out completely. Replace

the batteries as soon as possible after the

indicator starts flashing. If you do not replace

the batteries sometime during the flashing

“bAt Lo,” the indicator will eventually stop

20 to 30 seconds of removing the old ones,

you will not have to reprogram the thermostat.

However, if the display is blank, the batteries

are dead or incorrectly installed, and you will

have to reprogram. See pages 12 and 13 to

reprogram.

IMPORTANT:Although the thermostat has a

low battery indicator, replace the batteries

once a year to prevent the thermostat and

heatinrjcooling

system from shutting down

due to lack of battery power.

As a precaution, when leaving home for

longer than a month, change batteries before

you leave to prevent the system from shutting

down due to lack of battery power.

Program The Thermostat

After the batteries are installed, the thermostat

can be easily programmed in your hand

before it is installed on the wall.

If you would prefer to program the thermostat

after it is installed on the wall, skip to page

and return later to this programming section.

The following personal programming chart

(pages 10 to 11 ) may be helpful for planning

your program schedule of time and tempera-

ture settings for various times of the day.

Four time periods are available during

weekdays — “WAKE,” “LEAVE,” “

TURN,” and “SLEEP.” These periods can

be seen individually on the display as you

press the SET SCHEDULE key.

‘WAKE”

is the time period you want the

house at a comfortable temperature when

you get up and while you get ready for work

or school. (This will be a higher temperature

during heating season, or a lower tempera-

ture during cooling season.)

“LEAVE” is the time period you can set for

an energy-saving temperature while you are

away at work or school. (This will be a lower

temperature during heating season, or a

higher temperature during cooling season.)

“RETURN” is the time period you want the

house at a comfortable temperature for

activities before bedtime. (Again, higher

heat or lower cool.)

“SLEEP” is the time period you can set for

an energy-saving temperature while you are

sleeping. (Again, lower heat or higher cool.

For more comfortable sleeping, some

people choose not to raise the cool tem-

perature during the night.)

You will set one schedule for weekdays and

another for weekends, because your require-

ments will probably be different for each.

During weekends, only the “WAKE and

“SLEEP time periods are available.

Fill in the times and temperatures you desire

for weekdays and weekends. If you decide not

to program the thermostat, it will automatically

control heating at 68° F [20° C], and cooling at

78° F [26° C], 24 hours a day. Also, you do not

need to enter a time and temperature program

for all periods if your schedule does not

require it. For example, a house that is occu-

pied during weekdays would only require

programs for “WAKE and “SLEEP.”

If no program is entered for the weekends, the

thermostat will operate on the weekday

“SLEEP program all weekend.

When pressing the keys, use the ball of your

finger or a soft pencil eraser. Use of sharp

fingernails or pencil points can damage the

keypad.

If you make an error at any time during

programming, just press the RUN PROGRAM

key, and continue again at the step where you

left off.

Adjust Fan Operation Switch, As Required

The thermostat fan operation switch, labeled electric heat system, set the switch to “E. The

FUEL SWITCH (see illustration on page 17) is “E setting will allow the fan to turn on

setting for most systems. If your system is an

where the “G” terminal is connected.

Adjust System On-Time, As Required

The system on-time is

facto-~-set

for a warm

air, gas or oil heating system. If you are installing

it on another type of system, the system on-time

must be adjusted accordingly by setting screws A

and B on the back of the thermostat. Use the

heating system table shown in the illustration,

(page 17) as a guide. The system on-time should

be optimized according to the type of system to

minimize room temperature swings. Setting the

screw “out one turn” means turning the screw

approximately 360° counterclockwise, or about

one complete turn.

In the unlikely event that you want longer furnace

on-time, readjust screws A and/or B as follows:

First, turn both screws

completely, then adjust

for system type:

● Warm Air Furnace-Set at the Hot Water

setting, (A - out one turn, B - in).

● Electric Furnace-Leave at the Warm Air

Furnace setting (A - in, B - in).

NOTE: This thermostat does not have a setting for steam/gravity air. Cycles would not be long

enough for accurate temperature control.

IMPORTANT: When using a high

efficiency furnace such as a

90 percent or greater Average

Fuel Utilization Efficiency

(AFUE) unit, adjust screw A

OUT ONE TURN and screw

B IN.
