STEP 2. REMOVE OLD THERMOSTAT

!

Test your heating and cooling systems to make sure they work properly. If either system 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 the system at the furnace or the fuse/circuit breaker panel.

!

Carefully unpack your new thermostat and wallplate. Save package of screws, instructions, and receipt.

!

Remove the cover from the old thermostat. If the cover does not snap off when pulled firmly from the bottom, check for a screw or screws used to lock on the cover.

!

Loosen the screw or screws holding the thermostat to the wallplate and lift the thermostat away.

!

Disconnect the wires from the old thermostat. As you disconnect each wire, attach the enclosed labels with the old terminal designation. If there are only two wires, they do not need to be labeled. Wrap the wires around a pencil as shown to keep them from falling back into the wall.

Special Installations

Read this section if you are replacing:

• Clock thermostat with separate wires for the clock.

• Thermostat with six or more wires connected to it.

• Thermostat in a heating only system with three wires.

WIRES THROUGH

WALL OPENING

Replacing a Clock Thermostat that has C or C1 Clock Terminals

M5136

If you are replacing a Honeywell Chronotherm® Thermostat, you may find one or two wires going to the C or C1 clock terminals on the Chronotherm wiring wallplate. Do not allow them to touch, or you can damage the 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.

Replacing a Thermostat that has Six or More Wires

If there are six or more wires (excluding clock wires attached to terminals), you probably have a variation of a multistage heat pump or other multistage system. This thermostat is not compatible with multistage systems, so return the product to the place of purchase. For information about which programmable thermostats will work with your system, call Honeywell Customer Care at 1-800-468-1502.

69-1199—4 6

Replacing a Thermostat that has Three Wires

If you have three wires for a heating only system and can operate the fan using the fan ON switch this thermostat works with your system. However, some hot water (zoned) heating systems also have three wires. Your thermostat will work only if you install an isolating relay on these systems. For details, call your local heating and/or cooling contractor.

STEP 3. MOUNT THERMOSTAT WALLPLATE

!

Separate the wallplate from the thermostat by placing your thumb or fingers between the bottom of the wallplate and the thermostat, and pulling the wallplate up and away from the thermostat. See illustration at right.

!

Position the wallplate on the wall. Level the wallplate for appearance if desired. Use a pencil to mark the two mounting holes that best fit the application.

M16427

!

Remove the wallplate from the wall. Drill two 3/16 in. holes in wall

(if drywall) as shown. For materials such as plaster or wood, drill

7/32 in. holes where marked. Gently, tap the (provided) anchors into the drilled holes until they are flush with the wall.

!

Reposition the wallplate over the holes. Pull the wires through the wiring opening. Loosely insert mounting screws into each of the holes.

!

Level the wallplate if desired. Thermostat functions properly when not level.

!

Tighten mounting screws.

IMPORTANT

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

Refer to the labels you placed on the wires when you removed the old thermostat (see illustration).

!

Match the letter of your old thermostat wire with the corresponding terminal letter on your new thermostat. Refer to

Table 2.

!

Remove the factory-installed jumper connecting terminals R and

RC if wires are connected to both of those terminals.

!

For wiring diagrams, if needed, see pages 22-23.

!

Loosen the terminal screws. Slip each wire beneath its matching terminal. Wraparound and straight connections are both acceptable, (see illustration). Tighten the terminals.

!

If the thermostat is already mounted on the wall, remove the thermostat by placing your thumb between the thermostat and wallplate and pulling the thermostat up and away as shown.

When the batteries are running low, a REPL BAT message flashes for one to two months before the batteries run out completely.

Replace the batteries as soon as possible once the message flashes.

IMPORTANT

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

If you insert new batteries within 20 to 30 seconds of removing the old batteries, the system retains the current time and day. If the

M16424 display is blank, the batteries are dead or installed incorrectly. You must reset the time and day. Refer to Set the Clock for instructions.

As a precaution when leaving home for longer than a month, change batteries before leaving to prevent the system from shutting down due to lack of power. Always use fresh alkaline batteries. Nonalkaline batteries do not last as long. They also can leak, causing damage to the thermostat and the wall surface.

STEP 6. SET FAN OPERATION SWITCH

The thermostat fan operation switch, labeled FUEL SWITCH 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 allows the fan to turn on immediately with the heating or cooling in a system where the G terminal is connected.

SMART RESPONSE™ TECHNOLOGY

Your thermostat is actually a small computer. The Smart Response technology calculates the correct time of day to turn on your heating or cooling system. Smart Response technology considers the following information.

• Air temperature.

• Wall temperature.

• The time of day when you want the comfort temperature established.

When the thermostat activates Smart

Response technology, the thermostat displays In Recovery, changes the setpoint, and turns on the system.

• Your thermostat learns from experience. Each day it checks how closely it hit the recovery target and then adjusts the next days recovery start time accordingly.

• It takes a few days after installation for the thermostat to adjust to the local weather, your lifestyle, the construction of your home, and your heating/cooling system.

• You can turn off Smart Response technology by selecting Conventional

Recovery. See Step 8. Customize
