You made a smart choice by purchasing your new Honeywell thermostat; the smart thermostat that: · Keeps you comfortable by automatically calculating exactly when the furnace or air conditioning should go on to have the house at the desired comfort temperature by the time you wake up or return home. · Saves the maximum amount of energy and money by automatically remembering to adjust the temperature when you leave home or go to sleep. · Provides the ultimate in comfort and convenience. It comes preprogrammed. You can use the preprogrammed schedule, or set your own. This manual answers many of the questions that can arise as you become familiar and comfortable with your Honeywell thermostat -- the state of the art in home comfort controls. Read these instructions carefully. Failure to follow these instructions can damage the product or cause a hazardous condition. If this thermostat is replacing a control that contains mercury in a sealed tube, do not place your old 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.

PREPARE FOR INSTALLATION ! Check the contents of your thermostat package to be sure all items are included. Package Contents · · Thermostat Wiring labels · · Wallplate Screws and anchors · Owner's Guide ! Locate the required tools to install your thermostat. Tools Required · · · Screwdriver Hammer Level · · Drill Needle-nose pliers · Drill bits: 3/16 in. for drywall; 7/32 in. for plaster 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. 5 WIRES THROUGH WALL OPENING M5136 69-1532--2 Replacing a Clock Thermostat that has C or C1 Clock Terminals When 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. 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 wallplate from thermostat by placing your thumbs between bottom of wallplate and thermostat and pulling wallplate up and away from thermostat. See illustration. ! Position wallplate on wall. Level wallplate for appearance, if desired. Use a pencil to mark WALL WIRES two mounting holes that best fit the application. THROUGH WALL ! Remove wallplate from wall. Drill two 3/16 in. holes in wall (if drywall) as shown. WALL For plaster or wood, drill 7/32 in. holes as ANCHORS (2) marked. Gently tap (provided) anchors into drilled holes until flush with wall. ! Reposition wallplate over holes. Pull wires through wiring opening. Loosely insert mounting screws into each of the holes. MOUNTING HOLES ! Level wallplate, if desired. Thermostat MOUNTING SCREWS functions correctly, even when not level. ! Tighten mounting screws. M15044 M16427 69-1532--2 6 STEP 4. WIRE WALLPLATE TERMINALS 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 old thermostat wire with the corresponding terminal letter on new thermostat. Refer to Table 1. ! Remove factory-installed jumper connecting terminals R and RC if wires are connected to both of those terminals. ! For wiring diagrams, if needed, see Wiring Diagrams section. ! Loosen terminal screws. Slip each wire beneath matching terminal. Wraparound and straight connections are both acceptable, (see illustration). Tighten terminals. ! Plug the hole in the wall with insulation to help prevent drafts from adversely affecting thermostat operation. W R Y G M16425 FOR WRAPAROUND INSERTION STRIP 7/16 IN. (11 MM).

Tape off B. Tape off end of the wire with electrical tape and push the taped wire back into the wiring hole in the wall. WALLPLATE B STEP 5. INSTALL THE BATTERIES IMPORTANT Three fresh AA alkaline batteries must be installed for programming and operation of the thermostat and the heating/ cooling system. ! Install the batteries in the wallplate so the positive terminals all point up (see illustration). ! 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 on the next page. 69-1532--2 8 R RC O W Y G INSTALL 3 AA ALKALINE BATTERIES AS SHOWN, POSITIVE (+) TERMINALS TOWARD TOP.
