If not, return to retailer. For more information, call Honeywell Customer Assistance, toll-free 1-800-468-1502. TABLE 1--COMPATIBILITY CHART. System Type Compatible With CT3200 Gas--Standing Pilot Gas--Electronic Ignition Gas-Fired Boilers Gas--Millivolt Oil-Fired Boilers Oil-Fired Furnace Electric Furnace Electric Air Conditioning Baseboard Electric (120/240 Line Volt) Heat Pumps/Multistage Equipment Yes Yes Yes No Yes Yes Yes Yes No No 1 1 Not compatible with any 120/240 volt circuit. Will not work efficiently on steam or gravity systems. 1 Compatible with 2-wire Honeywell zone valves. Isolating relay required for 3-wire thermostats for zone valves. Not compatible with 2-wire White-Rodgers #1361 valves. 2 s Acquire tools and items as needed (below). Also purchase two AA alkaline batteries; we recommend Energizer batteries CROSS-RECESSED SCREWDRIVER HAND OR POWER DRILL WITH 3/16 INCH DRILL BIT, IF NEEDED TO DRILL HOLES IN WALL WIRE CUTTER/STRIPPER OR SHARP KNIFE, IF NEEDED TO STRIP WIRES MASKING TAPE, IF NEEDED TO LABEL WIRES AS THEY ARE DISCONNECTED FROM OLD THERMOSTAT SPIRIT LEVEL, IF NEEDED TO LEVEL THERMOSTAT FOR APPEARANCE M 878 3 STEP 2 Remove Old Thermostat s 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 10° C [50° F]. s TURN OFF POWER to system at the furnace, or at the fuse/circuit breaker panel. s Carefully unpack your new thermostat and mounting plate; save package of screws, instructions and receipt. s Remove cover from old thermostat. If it does not snap off when pulled firmly from the bottom, check for a screw used to lock on the cover. s Loosen screws holding thermostat to 4 subbase, wallplate or wall, and lift away. s Disconnect wires from old thermostat or subbase. 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. Keep the wires from falling back into the wall by wrapping them around a pencil, as shown. WIRES THROUGH WALL OPENING M5136 One or two extra wires? If you are replacing a Honeywell Chronotherm thermostat, you may find one or two wires that go to the C or C1 clock terminals on the Chronotherm thermostat wiring wallplate. Do not allow them to touch, or you may damage your 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. 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 5 not compatible with such systems so return the product to the place of purchase. If you would like information about which programmable thermostats will work with your system, call Honeywell Customer Assistance at 1-800-468-1502. 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. Call Honeywell Customer Assistance at 1-800-468-1502 for details. STEP 3 Install The Batteries IMPORTANT Batteries must be installed for programming and operation of the thermostat and heating/ cooling system. s Purchase two AA alkaline batteries; nonalkaline batteries will not last as long. We recommend Energizer batteries. s Make sure the thermostat is set in OFF position. s Use a coin to remove battery door. s Install the fresh batteries as shown, making sure positive and negative terminals are oriented correctly. s Replace battery door. 6 M1719B REMOVING BATTERY DOOR As the batteries are running low, a "bAt Lo" indicator will flash for 1-2 months before batteries run out completely. Replace the batteries as soon as possible after the indicator starts flashing. If you do not replace the batteries sometime during the flashing "bAt Lo" indicator, the indicator will eventually stop flashing. "bAt Lo" will stay on without flashing to indicate the thermostat and heating/cooling system have stopped working when the batteries are almost completely dead. After the batteries are completely dead, the "bAt Lo" indicator will disappear, leaving a completely blank display. Press down on left ends of batteries to remove. If you insert the new batteries within 20-30 INSTALL TWO AA ALKALINE BATTERIES AS SHOWN 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 12-13 to reprogram. 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. M1713 7 STEP 4 Program The Thermostat 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 10-11) may be helpful for planning your program schedule of time and temperature settings for various times of the day. Four time periods are available during weekdays -- "WAKE", "LEAVE", "RETURN", and "SLEEP". These periods can be seen individually on the display as you press the SET SCHEDULE key. 8 "WAKE" 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.) "LEAVE" 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.) "RETURN" is the time period you want the house at a comfortable temperature for activities before bedtime. (Again, higher heat or lower cool.) "SLEEP" 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 and another for weekends, since your requirements will probably be different for each. Also, during weekends only the "WAKE" and "SLEEP" time periods are available. Fill in the times and temperatures you desire for weekdays and weekends. If you decide not to program the thermostat, it will automatically control heating at 20° C [68° F], and cooling at 26° C [78° F], 24 hours a day. Also, you do not need to enter a time and temperature program for all periods if your schedule does not require it. For example, a house that is occupied during weekdays would not require programs for "LEAVE" and "RETURN". 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.
