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. Wrap wires around pencil to keep them WIRES THROUGH from falling back into WALL OPENING the wall, as shown. One or two extra wires? M5136 If you are replacing a ® Honeywell Chronotherm Thermostat, you may find one or two wires that go to the clock terminals on the Chronotherm thermostat wiring wallplate. Do not allow them to touch, or you can damage your transformer. Disconnect the wires 4 69-0733B--1 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 wallplate; save package of screws, instructions and receipt. Remove the cover from the 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. 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. 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. 5 69-0733B--1 STEP 3 Before You Program If you insert new batteries within 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. In this case, you will have to reprogram. See pages 13 through 15 to reprogram. If you do not reprogram, the factory-preproBACK OF THERMOSTAT grammed settings will be in effect, as shown in chart on pages 11 and 12. M8388 Install the Batteries IMPORTANT: Three AA alkaline batteries are included with the thermostat. Batteries must be installed for programming and operation of the thermostat and heating/cooling system. Install the batteries in back of the thermostat as shown, making sure positive (+) terminals all face toward the right. As the batteries are running low, a REPL BAT 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. INSTALL 3 AA ALKALINE BATTERIES AS SHOWN, POSITIVE (+) TERMINALS TOWARD RIGHT. 6 69-0733B--1 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. When leaving home for longer than a month, as a precaution, change batteries before you leave to prevent system from shutting down due to lack of battery power. Use fresh alkaline batteries; nonalkaline batteries will not last as long. We recommend Energizer® batteries. the factory-set Adaptive Intelligent RecoveryTM setting, or adjust it to conventional recovery. If you choose conventional recovery, adjust screw 3A (on the back of the thermostat) by turning OUT one turn. With Adaptive Intelligent RecoveryTM, your home will reach the comfort temperature gradually to be at the temperature you set at the exact time programmed into the thermostat. Maximum energy savings and comfort will be achieved. More about Adaptive Intelligent RecoveryTM... This thermostat is actually a small but powerful computer. When calculating the exact time to turn on your furnace or air conditioner, it considers: (1) air temperature, (2) the temperature of the wall and (3) when you want the comfort temperature established. 7 69-0733B--1 Adaptive Intelligent RecoveryTM Selection Before you program your thermostat, you must decide if you want to leave the thermostat at During recovery, the thermostat increases the control temperature gradually and turns the equipment on and off several times BEFORE reaching your comfort time to save energy by avoiding overshooting the comfort temperature. You can see the current control temperature anytime during recovery by pressing the CURRENT SETTING key. This smart control learns from experience. Each day it checks how closely it hit the target and adjusts the recovery start time accordingly. It normally takes FOUR TO EIGHT DAYS AFTER INSTALLATION for the thermostat to adjust to the weather, your lifestyle, home construction and heating/cooling system. With conventional recovery, the programmed time will mark the start of the time your furnace or air conditioner comes on to start recovery; therefore, you should program the start time to be earlier than the desired comfort time. The best starting time will vary as the seasons change, but 30 minutes is a good head start time to use. NOTE: If you adjust screw 3A for conventional recovery, a indicator will appear in the lower right corner of the thermostat display as a reminder that you are no longer using the PM TUE Adaptive Intelligent DAYTIME RecoveryTM feature. SET PT INDICATES THERMOSTAT IS SET FOR CONVENTIONAL RECOVERY M2483 8 69-0733B--1 STEP 4 Program The Thermostat MORNING is the time period you want the house at a comfortable temperature, after you get up, while you get ready for work or school. (This will be a higher temperature during heating season, or a lower temperature during cooling season.) DAYTIME 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.) EVENING is the time period you want the house at a comfortable temperature for activities before bedtime. (Again, higher heat or lower cool.) 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 11 and 12) may be helpful when planning your program schedule of time and temperature settings for various times of the day. Four time periods are available--MORNING, DAYTIME, EVENING and NIGHT. Each period has its own setting key. 9 69-0733B--1 NIGHT is the time period you can set for an energy-saving temperature while you are sleeping. (Again, lower heat or higher cool. Although for more comfortable sleeping, some people choose not to raise the cool temperature during the night.) You will set one schedule for weekdays, one for Saturday, and another for Sunday, because your requirements will probably be different for each. Fill in the times and temperatures you desire for weekdays, Saturday, Sunday. The factory-preprogrammed time and temperature settings are shown in parentheses. If you decide not to program the thermostat, it will automatically control to these settings. The thermostat requires a time and temperature program for the MORNING period. You can program DAYTIME and EVENING, or leave them blank. You can also change NIGHT or cancel it (see page 15), as you please. Before programming, remove the clear plastic overlay covering the display. 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 at any time during programming you make an error, just press the RUN PROGRAM key, and continue again at the step where you left off.

M5932 16 69-0733B--1 INSTALLATION Remove wallplate 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. Reposition wallplate over holes, pulling wires through wiring opening. Loosely insert two mounting screws into holes. Level for appearance only; thermostat will function properly even when not level. Tighten mounting screws. SPIRIT LEVEL M611A 17 69-0733B--1 STEP 6 Adjust System On-Length, Clock Display, As Required The thermostat on-length is factory-set for a warm air, gas or oil heating system. If you are installing it on another type of system, the onlength must be adjusted accordingly by setting screws 1A and 1B on the back of the thermostat, using the heating system table in the figure as a guide. The on-length should be optimized with the type of system to minimize If on-length screws 1A,1B are adjusted to match this system: electric warm air gas/oil warm air hot water or high efficiency 18 room temperature swings. Setting the screw out one turn means turning the screw approximately 360°, or about one complete turn. In the rare event that you want a longer onlength, you may readjust the screws as follows, but be aware that you may be increasing room temperature swings at the same time. For longer on-length, readjust screws 1A,1B to match this system: gas/oil warm air hot water or high efficiency gravity air/water 69-0733B--1 INSTALLATION IMPORTANT: When using a high efficiency furnace such as a 90% or greater AFUE (Average Fuel Utilization Efficiency) unit, adjust screw 1A in and screw 1B out one turn. The thermostat is set to display the time as a 12-hour clock and the temperature in degrees Fahrenheit. If a 24-hour clock (e.g., military time) or degrees Celsius readings are desired, adjust screws 2A and 2B as necessary using the figure as a guide.

The heating equipment should shut off. Move the system switch to COOL and the fan switch to AUTO. 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 will delay up to five minutes before turning on the air conditioner. This delay protects the compressor. HEAT OFF COOL FAN ON AUTO Temp Press down arrow of key until setting is about 10° F [6° C] below room temperature. The cooling equipment and fan should start. 27 69-0733B--1 Temp Press up arrow of key until the setting is about 10° F [6° C] above room temperature. The cooling equipment and fan should stop. Move the system switch to OFF and the fan switch to ON. The fan should run continuously. When the fan switch is in the AUTO position, fan cycles with the heating or cooling system. HEAT OFF COOL FAN ON AUTO 28 69-0733B--1 STEP 11 Set The Fan And System Switches First set the fan switch. FAN ON: The fan runs continuously. Use for improved air circulation during special occasions or for more efficient electronic air cleaning. FAN AUTO: Normal setting for most homes. A single-speed fan will turn on automatically with the air conditioner or furnace. A twospeed fan will usually run on high with the air conditioner and on low with the furnace. Then set the system switch. HEAT: The thermostat controls your heating system. OFF: Both the heating and air conditioning systems are off. COOL: The thermostat controls your air conditioning system 29 HEAT OFF COOL FAN ON AUTO FAN ON AUTO HEAT OFF COOL HEAT OFF COOL 69-0733B--1 Troubleshooting Guide IF... Display will not come on. THEN... Install batteries backwards for a few seconds to reset thermostat; replace batteries correctly. Make sure batteries are fresh. Make sure batteries are installed correctly. Display flashes during programming. Temperature change occurs at the wrong times. You have reached the temperature setting limit. The setting range is 45° F to 88° F [7° C to 31° C]. Check the program times for the period in question. Be sure that AM and PM indications are correct. Make sure the current day and time are correct. Reprogram if necessary. If you left the thermostat set for Adaptive Intelligent RecoveryTM, the start times will occur before your programmed comfort periods. 30 69-0733B--1 Heating will not come on. Check the fuse or circuit breaker and replace or reset if necessary. If display is blank or says REPL BAT, install fresh batteries. Check that switch on thermostat is set to HEAT. If temperature setting is higher than current temperature, and display says HEAT ON, contact Honeywell Customer Assistance at 1-800-468-1502. Cooling will not come on. Check the fuse or circuit breaker and replace or reset if necessary. If display is blank or says REPL BAT, install fresh batteries. Check that switch on thermostat is set to COOL. The thermostat has a built-in time delay on cooling. Allow up to ten minutes after changing the setting before the air conditioner starts. If temperature setting is lower than current temperature, and display says COOL, move system switch from COOL to OFF for ten minutes. After ten minutes, return the switch to the COOL 31 69-0733B--1 position. If your air conditioner comes on, this indicates your compressor may have reached its high limit temperature protection and shut down. If your air conditioner does not come on after ten minutes and the display says COOL, contact Honeywell Customer Assistance at 1-800-468-1502. The house is too warm or too cool. Press CURRENT SETTING to check the current temperature setting. If desired, change the temperature setting. See page 15. Display says HEAT ON, but no heat is coming from the registers. The system cycle length is too short or too long. Allow time for the furnace to heat up and the fan to come on before checking for heat at the register. Note that on most gas and oil systems, the fan is not controlled by the thermostat, but by another control, which may account for the delay. Readjust according to instructions on pages 18 and 19. 32 69-0733B--1 The thermostat's current setting does not match the display temperature. Check that the wiring hole in the wall behind the wallplate has been plugged with insulation to prevent drafts that might adversely affect thermostat operation. Be aware that it is normal for the current setting and display temperature to differ occasionally. 33 69-0733B--1 Index Adaptive Intelligent RecoveryTM ....................... 7,8 Batteries, installation .............. 6 Batteries, replacement ........ 6,7 Blinking display ....................... 6 Canceling programs ............. 15 Change temperature ............. 15 Checking current setting ....... 15 Clock display ........................ 19 Conventional Recovery ....... 7,8 Cooling temperatures ........ 9,11,12,14 Current setting ...................... 15 Customer Assistance ............ 35 Day ........................................ 13 DAYTIME .................... 13,14,15 Energy-saving temperature ......................... 9 EVENING .................... 13,14,15 Fan operation switch ............ 20 Fan switch ............................. 29 Flashing display ...................... 6 Heating temperatures ........ 9,11,12,13 Hold temperature .................. 15 MORNING .................. 13,14,15 NIGHT ......................... 13,14,15 Operation .............................. 15 Period keys ............................. 9 Personal programming chart .............................. 11,12 Preprogrammed schedule ............... 9,10,11,12 Programming steps ......... 13,14 Replacing batteries .............. 6,7 Saturday program ......... 10,11,12,13,14 Set cooling temperatures ..... 14 Set present day .................... 13 Set present time ................... 13 Set fan switch ....................... 29 Set heating temperatures ..... 14 Setting limits .................... 11,12 Sunday program ......... 10,11,12,13,14 System switch ....................... 29 Switch,fan ............................. 29 Switch, system ...................... 29 Table of Contents ................... 1 Temporary program changes ........................... 15 Time ...................................... 13 Time period .............. 9,10,11,12 Troubleshooting ..... 30,31,32,33 Warranty ............................... 36 Weekday program ........... 9,10,11,13,14 34 69-0733B--1 Toll-free Customer Assistance For all questions concerning this thermostat, please read and follow the instructions.

TOURNEVIS CRUCIFORME PERCEUSE MANUELLE OU ÉLECTRIQUE AVEC MÈCHE DE 3/16 po POUR PERCER DES TROUS DANS LE MUR COUPE-FILS, PINCE À DÉNUDER OU COUTEAU BIEN AFFÛTÉ S'IL EST NÉCESSAIRE DE DÉNUDER DES FILS RUBAN-CACHE, POUR IDENTIFIER AU BESOIN, LES FILS LORSQU'ILS SONT DÉBRANCHÉS DE L'ANCIEN THERMOSTAT NIVEAU À BULLE, S'IL EST NÉCESSAIRE DE METTRE LE THERMOSTAT DE NIVEAU À DES FINS D'ESTHÉTIQUES MF878 3 69-0733B--1 ÉTAPE 2 Retrait de l'ancien thermostat Desserrer les vis qui retiennent le thermostat à la plaque de montage, à la plaque murale ou au mur, puis soulever le thermostat. Débrancher les fils de l'ancien thermostat ou de la plaque de montage. Étiqueter les fils à l'aide de ruban-cache en FILS PAR inscrivant la lettre L'OUVERTURE DU MUR correspondant à l'ancienne borne. Ne pas identifier les fils s'il n'y en a que deux. Enrouler les MF5136 fils autour d'un crayon pour empêcher qu'ils ne tombent dans le mur (voir illustration). Vérifier si les systèmes de chauffage et de refroidissement fonctionnent correctement. Si l'un ou l'autre ne fonctionne pas, communiquer avec le représentant en système de chauffage et de refroidissement. Pour ne pas endommager le compresseur, ne pas faire fonctionner le système de refroidissement lorsque la température extérieure est inférieure à 10 °C (50 °F). COUPER L'ALIMENTATION du système à l'appareil de chauffage ou au panneau de disjoncteurs ou des fusibles. Déballer minutieusement le nouveau thermostat et la plaque de montage; conserver les vis, les instructions et le reçu. Enlever le couvercle de l'ancien thermostat. S'il ne s'enlève pas lorsqu'on le tire fermement par le bas, vérifier si une vis le retient en place. 4 69-0733B--1 Un ou deux fils supplémentaires ? Certains thermostats Chronothermmd de Honeywell ont un ou deux fils qu'il faut raccorder aux bornes de l'horloge sur la plaque murale du thermostat. Ces fils ne doivent pas se toucher sinon le transformateur pourrait être endommagé. Débrancher les fils et les recouvrir, chacun, de ruban isolant. Ne pas les envelopper ensemble. Les placer de manière qu'ils ne nuisent pas au fonctionnement du nouveau thermostat. Inscrire la couleur et l'appellation des autres fils. Six fils ou plus ? S'il y a six fils ou plus (à l'exclusion des fils de l'horloge reliés aux bornes), il s'agit probablement d'un système de pompe à chaleur ou d'un système multi-étages. Le thermostat n'est pas compatible avec ces systèmes. 5 Thermostats trifilaires ? S'il y a trois fils pour le chauffage seulement et qu'il est possible de faire fonctionner le ventilateur au moyen du commutateur ON, ce thermostat fonctionnera avec le système. Mais il faut prendre garde: certains systèmes de chauffage à eau chaude (par zone) possèdent des thermostats trifilaires. Sur ces systèmes, il faut installer un relais d'isolement pour faire fonctionner le thermostat. 69-0733B--1 ÉTAPE 3 Avant de programmer le thermostat Si les nouvelles piles sont remplacées 20 à 30 secondes après l'enlèvement des anciennes, il n'est pas nécessaire de reprogrammer le thermostat. Si l'affichage disparaît, les piles sont soit mortes, soit incorrectement installées. Il faut reprogrammer le thermostat (voir pages 13-15). S'il n'est pas reprogrammé, le thermostat ARRIÈRE DU THERMOSTAT fonctionnera selon les réglages déterminés en usine (voir pages 11 et 12). MF8388 Installation des piles IMPORTANT: Trois piles alcalines AA sont fournies avec le thermostat. Pour programmer et faire fonctionner le thermostat et le système de chauffage ou de refroidissement, il faut installer ces piles. Installer les nouvelles piles à l'arrière du thermostat, la borne positive vers la droite (voir illustration). Lorsque les piles faibliront, un voyant «REPL BAT» commencera à clignoter 1 à 2 mois avant que les piles ne soient complètement mortes. Il faut remplacer les piles sans tarder. 6 INSTALLER TROIS PILES ALCALINES AA, COMME ILLUSTRÉ, LA BORNE POSITIVE VERS LA DROITE 69-0733B--1 IMPORTANT: Bien que le thermostat soit muni d'un indicateur de faible intensité, il est préférable de remplacer les piles une fois par année pour éviter que le thermostat et le système de chauffage ou de refroidissement ne s'arrêtent en raison des piles mortes. Avant de partir pour une période de plus d'un mois, il est bon de remplacer les piles pour éviter que le thermostat ne s'arrête parce que les piles ne sont plus bonnes. Utiliser des piles alcalines neuves (les autres types de piles ne dureront pas aussi longtemps). Nous recommandons l'emploi des piles Energizermd. réglé en usine, ou le mode de récupération traditionnelle. Pour régler le thermostat en mode récupération traditionnelle, tourner la vis 3A (à l'arrière du thermostat) un tour à gauche. Grâce au mode Adaptive Intelligent Recoverymd, la température variera graduellement de sorte qu'au moment déterminé, la température de confort sera atteinte. Ce mode de récupération assure un confort et des économies d'énergie maximums. Autres renseignements sur le mode Adaptive Intelligent Recoverymd... Le CT3400 est un petit ordinateur, très puissant. Pour déterminer l'heure exacte de mise en marche ou d'arrêt de l'appareil de chauffage ou de refroidissement, il tient compte des facteurs suivants: 1. température de l'air; 2. température des murs; 3. moment où la température de confort doit être atteinte. Sélection du mode Adaptive Intelligent Recoverymd Au moment de programmer le thermostat, il faut choisir entre le mode Adaptive Intelligent Recovery, 7
