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.

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 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 Relations Center, at 1-800-468-1502.

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.

❑ 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 pp 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.
