M3375

Welcome to the world of energy savings with your new Honeywell fuel saver thermostat. The

Honeywell name is your assurance of accurate control and reliable operation for years to come.

Your new thermostat will automatically lower and raise the temperature in your home one or

more times every 24 hours. This allows you to significantly lower your fuel costs, while awakening

(or returning home) to a comfortable temperature.

Read this manual to learn how to use your new thermostat.

Recycling Notice

This control contains mercury in a sealed tube. Do

not

place control in the trash at the end of its

useful life.

If this control is replacing a control that contains mercury in a sealed tube, do

not

place your

control in the trash.

Contact your local waste management authority for instructions regarding recycling and the

proper disposal of this control, or of an old control containing mercury in a sealed tube.

If you have questions, call Honeywell Inc. at 1-800-468-1502.

Setting the Temperature

For Heating

Set the left lever (blue mark) to the energy

savings temperature you want when you are

sleeping or your home is unoccupied.

Set the right lever (red mark) to the tempera-

ture you want for normal comfort periods.

NOTE: You may override the time program by

setting both the red and blue levers to the

same temperature setpoint.

For Cooling

Set the left lever (blue mark) to the tempera-

ture you want for normal comfort periods.

Set the right lever (red mark) to the energy

savings temperature you want when you are

sleeping or your home is unoccupied.

Setting Subbase Switches

(If applicable)

The subbase system switch controls system

operation as follows:

HEAT—Heating system is controlled by the

thermostat. Cooling system is off.

COOL—Cooling system is controlled by the

thermostat. Heating system is off.

OFF—Both the heating and cooling systems

are off. If the fan switch is at the AUTO

position, the fan is also off.

AUTO—In a cooling only application, only

cooling operates. In a heating only applica-

tion, only heating operates.

The subbase fan switch controls fan operation

as follows:

ON—Fan operates continuously.

AUTO—Fan operates with cooling equipment

as controlled by the thermostat or with the

heating equipment as controlled by the

plenum fan switch. In electric heat, heat

pump, and fan coil systems, the fan is

controlled by the thermostat in heating and

cooling.

To switch positions, use thumb or index

finger to slide lever to desired position. For

proper circuit operation, stop switch lever in the

detent over desired function indicator mark.

Inserting Clock Batteries

Power is supplied to the clock by the 24 Vac

transformer, by two AAA alkaline batteries

(included), or by the heating or cooling control

circuit. Backup batteries can be installed to

supply power to the clock if power is interrupted

when using 24 Vac powering method. Install

batteries in thermostat as shown in Fig. 2. Once

a year or when batteries are dead, replace with

two new AAA alkaline batteries. We recom-

mend Energizer

batteries.

Setting the Clock

Lift thermostat flip-up cover and you will find

the 24-hour program dial, slotted in ten minute

increments. Adjust the clock to the current time

by moving the minute hand carefully in a clock-

wise direction. DO NOT reverse the

minute hand.

When time is correctly set, the Time Indica-

tor Arrow (see Fig. 3) points to the correct time

and corresponding daytime (light) or nighttime

(dark) band of the program dial.

EXAMPLE: For 11 PM, the time indicator arrow

points directly to dark band. For 11 AM, the

arrow points to the light band on the dial.

Daylight Savings Time

When Daylight Savings Time starts, carefully

move the minute hand in a clockwise

direction one hour. When Daylight Savings Time

ends, carefully move the minute hand in a

clockwise direction 23 hours. Do NOT

reverse the minute hand, or damage to the timer

mechanism can occur.

Fig. 3—Setting the Clock.

11 69-0628B—1

Programming

You can program your thermostat to

automatically lower and raise the temperature

one or more times every 24 hours, depending

on the number of program pins used.

Before setting your program

Lift thermostat flip-up cover and you will find

the 24-hour program dial. The slots on the

program dial (Fig. 4) are for the program pins

that can be inserted at ten minute intervals.

Three red and three blue program pins are

included with your thermostat. The red pins start

the high-temperature period; the blue pins start

the low-temperature period. A heating program

has been preprogrammed. A red pin is inserted

at 6:00 AM for high temperature (comfort period);

a blue pin is inserted at 10:00 PM for low

temperature (energy saving period). Two

additional sets of pins are located in the program

pin storage area. You can set up to six tem-

perature changes with the pins supplied. We

recommend at least five hours for each energy

saving period.

To change the pins or add a new energy

savings period—

• To insert a pin, push it straight into the selected

notch on the program dial until it is completely

seated.

• To remove a pin, press against the program dial

and pull the pin straight out. DO NOT attempt to

change a pin if it is engaged with the program

index wheel.

• On heating/cooling systems, you must reset the

pins when the seasons change. You will also

probably want to change the lever positions.

Setting the Heating Program

Decide when you want the temperature to

reach the comfort level. Find the notch on the

dial that is one-half hour before this time and

insert a

red

pin. The half-hour head start gives

the furnace time to heat the house before you

wake up or arrive home.

Decide when you want the energy savings

period to start and insert a

blue

pin at the notch

that corresponds to this time. After the blue pin

engages, the furnace will be off until room

temperature drops to the energy savings set

point.

You can set both a day and a night program.

See Fig. 5 for program examples.

Setting the Cooling Program

Decide when you want the temperature to

reach the comfort level. Find the notch on the dial

that is one-half hour before this time and insert a

blue

pin. The half-hour head start gives the air

conditioner time to cool the house before you

wake up or arrive home.

Decide when you want the energy savings

period to start and insert a

red

pin in the notch

that corresponds to this time. After the red pin

engages, the air conditioner will be off until room

temperature rises to the energy savings setpoint.

NOTE: Due to weather and system variations,

the program pins may need to be relocated for

optimum start time of heating or cooling equip-

ment during recovery from energy savings.

Start or End Programs with

Manual Program Advance Button

IMPORTANT:

To prevent damage to the

program advance mechanism. DO NOT

use the program advance button within a

30-minute period before or after a program

change.

The manual program advance button enables

immediate, one-time-only program changes to

accommodate temporary schedule changes.

Press the button to immediately begin an

energy savings period or return to the normal

setting. After pressing the button, check the

program indicator to ensure the system is in the

desired mode. If the program indicator shows

blue, the lower temperature is in effect; if it shows

red, the higher temperature is in effect. Using the

manual advance button will not affect the stored

program.
