STEP 2 Remove Old Thermostat

☐ 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.

☐ Remove 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.

☐ 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 thermostat, you will also 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.

WIRES THROUGH WALL OPENING M5136

Replacing a Clock Thermostat that has C or C1 Clock Terminals?

If you are replacing a Honeywell Chronotherm® Thermostat, you may find one or two wires that go to the C or C1 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 separately, 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

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 programmable 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.

STEP 3 Install The Batteries

IMPORTANT

Batteries must be installed for programming and operation of the thermostat 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.
□ 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.

REMOVING BATTERY DOOR M3631

As the batteries are running low, a "bAt Lo" indicator will flash for 1 to 2 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

6

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 BATTERIES AS SHOWN Set Time Temp Mode Fan Auto On System Coat Off Heat M3668

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 to 13 to reprogram.

IMPORTANT

Although the thermostat has a low battery indicator, replace the batteries once a year to prevent the thermostat and heating/cooling 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 system from shutting down due to lack of battery power.

STEP 4 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 16, 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 temperature settings for various times of the day.

Four time periods are available during weekdays—"WAKE," "LEAVE," "RETURN," 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 temperature 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.)

8

"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 temperature during the night.)

You will set one schedule for weekdays and another for weekends, because your requirements will probably be different for each. Also, 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 occupied 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 may 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.

STEP 5

Adjust Fan Operation Switch, As Required

☐ The thermostat fan operation switch, labeled FUEL SWITCH (see illustration on page 17) is factory-set in the "F" position. This is the correct setting for most systems. If your system is an

electric heat system, set the switch to "E." The "E" setting will allow the fan to turn on immediately with the heating or cooling in a system where the "G" terminal is connected.

STEP 6

Adjust System On-Time, As Required

☐ The system on-time is factory-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 on 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° or one complete turn. Setting the screw "in" means tightening the screw completely down.

In the unlikely event that you want longer furnace on-time, readjust screws A and/or B as follows:

16

First, turn both screws in 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 AFUE (Average Fuel Utilization Efficiency) unit, adjust screw A OUT ONE TURN and screw B IN.

STEP 7 Mount Thermostat Mounting Plate

☐ Position mounting plate on wall. Use a level to make sure mounting plate is level. Use a pencil to mark the two mounting holes.
☐ Remove mounting plate from wall, and drill 3/16 inch holes in wall (if drywall) as marked. For firmer material such as

plaster or wood, drill 7/32 inch holes. Gently tap anchors (provided) into drilled holes until flush with the wall.

STEP 8 Wire Thermostat Terminals

NOTE: All wiring must comply with local codes and ordinances. If unsure about household wiring procedures, call your local heating/air conditioning contractor.

Refer to masking tape labels you placed on wires when you removed your old thermostat.

☐ Match the letter of your old thermostat wire with the terminal of the corresponding letter on the back of your new thermostat. Refer to illustrations on pages 22 and 23. Hold the thermostat as shown to minimize need for wire extenders. If wires are still too short, use wire connectors (purchased locally) to extend wires. See illustration (right) for guidelines on using wire extenders.

☐ In 5-wire installations only, be sure to remove the factory-installed jumper connecting terminals R and Rc.

STEP 10

Check Thermostat Operation After Programming And Installing

HEATING

Do not check heating system operation by jumpering thermostat terminals at the primary control such as the gas valve, zone valve, or oil burner control. This will damage the thermostat. Instead, you could jumper R and W wires at the thermostat.

Cool Off Heat Auto On

Move the system switch to HEAT and the fan switch to AUTO.

Press key until the setting is about 10^ F [6°C] above room temperature. Heating should start and the fan should run after a short delay (immediately if fan operation switch is set in E position).

Press key until setting is about 10^ F [6°C] below room temperature. The heating equipment should shut off.

24

COOLING

To avoid possible compressor damage, do not operate the cooling system when outside temperature is below 50°F [10°C]. See compressor manufacturer instructions for further information.

NOTE: When cooling setting is changed, thermostat may delay up to five minutes before turning on the air conditioner. This delay protects the compressor.

Cool Off Heat Auto On

Move the system switch to COOL and the fan switch to AUTO.

Press key until setting is about 10^ F [6°C] below room temperature. The cooling equipment and fan should start.

Press key until the setting is about 10^ F [ 6^ C] above room temperature. The cooling equipment and fan should stop.

Cool Off Heat Auto On

Move the system switch to OFF with the fan switch still at AUTO. The system and fan should be off.

STEP 11

Set The Fan And System Switches

First set the Fan switch.

FAN AUTO: Normal setting for most homes. A single-speed fan will turn on automatically with air conditioner or furnace. A two-speed fan will usually run on high with air conditioner and on low with furnace.

Exception: If Fan Operation Switch on back of thermostat is set to "E" position (see page 16), fan will operate with furnace only.

FAN ON: The fan runs continuously. Use for improved air circulation during special occasions or for more efficient electronic air cleaning. (In a heat-only system, fan will run continuously only if fan relay is connected to the thermostat.)

26

Then set the System switch.

COOL: The thermostat controls your air conditioning system.

OFF: Both the heating and air conditioning systems are off.

HEAT: The thermostat controls your heating system.
