Step 1. Prepare for Installation
Check Table 1 to make sure this thermostat is compatible with your system. If not, return it to the retailer. For more information, call Honeywell Consumer Services, 1-800-468-1502, Monday Friday, 7 am to 5:30 pm, Central time.

Step 2. Remove Old Thermostat
Test to be sure 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 the system at the furnace, or at the fuse/circuit breaker panel. Carefully unpack your new thermostat and mounting plate, saving package of screws, instructions and receipt. 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.
Loosen screws holding thermostat to subbase, wallplate or wall, and lift away. Disconnect wires from old thermostat or subbase. As you disconnect each wire, attach one of the enclosed labels to each old terminal designation. If there are only two wires, they do not need labeling. If there is an extra wire that is not connected to your old thermostat, you also do not connect it to your new thermostat. Keep the wires from falling back into the wall by wrapping them around a pencil as shown.

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 that go to the C or C1 clock terminals on the Chronotherm® Thermostat wiring wallplate. Do not allow them to touch, or you can damage your transformer. Disconnect the wires and wrap them separately, using electrical tape. Do not wrap them together. Place the wires where they do not interfere with the operation of the new thermostat. Record the colors and terminal designation labels of the remaining wires.
those systems so return the product to the retailer. If you want information about the programmable thermostats that work with your system, call Honeywell Consumer Services 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 works with your system. However, some hot water (zoned) heating systems have three thermostat wires. The thermostat does not work without installing an isolating relay on these systems. For details, call Honeywell Consumer Services at 1-800-468-1502.
Six or more wires?
If there are six or more wires (excluding clock wires attached to terminals), you probably have a variation of a heat pump or multistage system. This thermostat is not compatible with

Step 3. Install Batteries
IMPORTANT Batteries must be installed for the programming and operation of the thermostat and heating/cooling system. Purchase two AA alkaline batteries; nonalkaline batteries do not last as long, and can leak, causing damage to the thermostat or the wall surface. We recommend Energizer® batteries. Open the top cover of thermostat to access control panel and battery compartment. Make sure the thermostat is set to the Off position. Use a coin to remove the battery cover.

Install the fresh batteries as shown, making sure positive and negative terminals are oriented correctly. Replace the battery cover. As the batteries run low, a bAt Lo indicator flashes for one to two months before the 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, the indicator eventually stops flashing. bAt Lo then stays on without flashing, indicating the thermostat and heating/cooling system have stopped working and the batteries are almost completely dead.
After the batteries are completely dead, the bAtLo indication disappears, leaving a completely blank display.

Press down on the left ends of batteries to remove them. If you insert the new batteries within 20 to 30 seconds of removing the old ones, you do not need to reprogram the thermostat. However, if the display is blank, the batteries are dead or incorrectly installed and you must reprogram. See Step 4.
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. As a precaution, when leaving home for longer than a month, change batteries before you leave to prevent the system from shutting down due to lack of battery power.

Step 4. Program Thermostat
After the batteries are installed, the thermostat can be easily programmed in your hand before it is installed on the wall. If you prefer to program the thermostat after it is installed on the wall, go to Step 7 and return later to this programming section. The Personal Programming Chart, Tables 2 and 3, 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; view these periods individually on the display as you press the Weekday key.
· WAKE is the time period you want the house at a comfortable temperature when you get up and while you get ready for work or school. (This is a higher temperature during heating season and 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 is a lower temperature during heating season and a higher temperature during cooling season.) · RETURN is the time period you want the house at a comfortable temperature for activities before bedtime. (This is a higher temperature during heating season and a lower temperature during cooling season.) · SLEEP is the time period you can set for an energy-saving temperature while you are sleeping. (This is a lower temperature during the heating season and a higher temperature during the cooling season.)

Set one schedule for weekdays and another for weekends because your requirements are usually 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 automatically controls heating at 68°F (20°C), and cooling at 78°F (26°C), 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 require programs only for WAKE and SLEEP.
If no program is entered for the weekends, the thermostat operates on the weekday SLEEP program all weekend. 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. Using sharp fingernails or pencil points can damage the keypad. If you make an error at any time during programming, just press the Run Program key, and continue again at the previous step in your sequence.
