STEP 2. REMOVE OLD THERMOSTAT❑ Test to make certain that your heating and

cooling systems are working properly. Ifeither does not work, contact your localheating/air conditioning dealer. To avoidcompressor damage, do not operate thecooling system when outdoor temperatureis below 50°F (10°C).

❑ Turn off power to system at the furnace, orat the fuse/circuit breaker panel.

❑ Carefully unpack your new thermostat andwallplate; save package of screws,instructions and receipt.

❑ Remove the cover from the old thermo-stat. If it does not snap off when pulledfirmly from the bottom, check for a screwused to lock on the cover.

❑ Loosen screws holding thermostat tosubbase, wallplate or wall, and lift away.

❑ Disconnect wires from old thermostat orsubbase. As you disconnect each wire,attach theenclosedlabels withthe oldterminaldesignation.If there areonly twowires, they do not need to be labeled.Wrap wires around pencil to keep themfrom falling back into the wall, as shown.

Replacing a clock thermostat that hasC or C1 clock terminals?If you are replacing a HoneywellChronotherm® Clock Thermostat, you mayfind one or two wires that go to the C or C1clock terminals on the Chronotherm® wiringwallplate. Do not allow them to touch, or youcan damage your transformer. Disconnect thewires and wrap them separately usingelectrical tape; do not wrap them together.Place the wires where they will not interferewith the operation of the new thermostat.Record the colors and terminal designationlabels of the remaining wires.

Six or more wires?If there are six or more wires (excluding clockwires attached to terminals), you most likelyhave a variation of a multistage heat pump orother multistage system. The thermostat is

not compatible with such systems so returnthe product to the place of purchase. If youwould like information about which program-mable thermostats will work with yoursystem, call Honeywell Customer AssistanceCenter at 1-800-468-1502.

Three thermostat wires?If you have three wires for a heating onlysystem and can operate the fan using the fanON switch, this thermostat will work with yoursystem. However, some hot water (zoned)heating systems have three thermostat wires.The thermostat will work only if you install anisolating relay on these systems. For details,call Honeywell Customer Assistance Centerat 1-800-468-1502.

WALLANCHORS(2)

❑ Position wallplate on wall. Level thewallplate for appearance if desired. Use apencil to mark the two mounting holes thatbest fit the application.

❑ Remove wallplate from wall, and drill3/16 inch holes in wall (if drywall) asmarked. For firmer material such asplaster or wood, drill 7/32 inch holes.Gently tap anchors (provided) into drilledholes until flush with the wall.

❑ Reposition wallplate over holes, pullingwires through wiring opening. Looselyinsert two mounting screws into holes.

❑ Level for appearance only; thermostatfunctions properly even when not level.Tighten mounting screws.

9 69-0939—1

STEP 4. WIRE WALLPLATE TERMINALSNOTE: All wiring must comply with local

codes and ordinances. If unsureabout household wiring procedures,call your local heating/air condition-ing contractor.

Refer to the labels you placed on wires whenyou removed your old thermostat.

❑ Match the letter of your old thermostatwire with the terminal of the correspond-ing letter on your new thermostat. Refer toillustrations on pages 10, 11, and 12.

Be sure to remove the factory-installedjumper connecting terminals R and Rc whenwires are connected to both the R and Rcterminals.

❑ Loosen the terminal screws and slip eachwire beneath its matching terminal. Eitherstraight or wraparound wiring connectionsare acceptable (see illustration). Tightenterminals.

❑ Plug the hole in the wall with insulation tohelp prevent drafts from adverselyaffecting thermostat operation.

STEP 5. INSTALL THE BATTERIESIMPORTANT

Three AA alkaline batteries areincluded with the thermostat.Batteries must be installed forprogramming and operation of thethermostat and heating/coolingsystem.

❑ Install the batteries on the wallplate asshown, making sure positive (+) terminalsall face upward.

As the batteries are running low, a REPL BATindicator will flash for 1 to 2 months beforebatteries run out completely. Replace thebatteries as soon as possible after theindicator starts flashing.

If you insert new batteries within 20 to 30seconds of removing the old ones, you willnot have to reset the current time. However, ifthe display is blank, the batteries are dead orincorrectly installed. See page 22 to resetcurrent time and day.

14 69-0939—1

IMPORTANTAlthough the thermostat has a lowbattery indicator, replace thebatteries once a year to preventleakage and to prevent thethermostat and heating/coolingsystem from shutting down due tolack of battery power.

As a precaution when leaving home forlonger than a month, change batteries beforeyou leave to prevent system from shuttingdown due to lack of battery power.

Use fresh alkaline batteries; nonalkalinebatteries do not last as long, and may leak,causing damage to the thermostat or the wallsurface. We recommend Energizer®batteries.

STEP 6. SET FANOPERATION SWITCHThe thermostat fan operation switch, labeledFUEL SWITCH is factory set in the F position.This is the correct setting for most systems. Ifyour system is an electric heat system, setthe switch to E. The E setting allows the fanto turn on immediately with the heating orcooling in a system where the G terminal isconnected.

The thermostat display shows day, time,program period, temperature and systemoperation selection.

There is an individual key for each of the fourtime periods—

—the time period you want the houseat a comfortable temperature when youget up and while you get ready for workor school. (This will be a highertemperature during the heating seasonand a lower temperature during thecooling season.)

—the time period you can set for anenergy-saving temperature while youare away at work or school. (This will bea lower temperature in the heatingseason and a higher temperatureduring the cooling season.)—the time period you want the house ata comfortable temperature for activitiesbefore bedtime. (Again, higher heat andlower cool.)—the time period you can set for anenergy-saving temperature while youare sleeping. (Again, lower heat andhigher cool. Some people choose not toraise the cooling temperature for morecomfortable sleeping.)
