STEP 2 Remove Old Thermostat
■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].
■TURN OFF POWER to system at the furnace, or at the fuse/circuit breaker panel.
■Carefully unpack your new thermostat and mounting plate; save 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, 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.

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
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.
■ Purchase two AA alkaline batteries; non- |

mend Energizer batteries. |
|
■ Make sure the thermostat is set in OFF position. |
M1719B |
|
■Use a coin to remove battery door.
■Install the fresh batteries as shown,
making sure positive and negative terminals are oriented correctly.
■ Replace 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”
6
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
M1713
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.

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.
“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
8
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.

STEP 5 Adjust Fan Operation Switch, As Required
■ The thermostat fan operation switch, labeled FUEL SWITCH (see figure on page 17) is factoryset in the “F” position. This is the correct setting for most systems. If your system is an electric heat
system, set the switch to “E”. The “E” setting will allow the fan to turn on immediately with the heating or cooling in a system where the “G” terminal is connected.
STEP 6 Adjust System On-Length 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 on-length must be adjusted accordingly by setting screws A and B on the back of the thermostat, using the heating system table in the figure
(page 17) as a guide. The on-length should be optimized according to the type of system to minimize 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 on-length, you may readjust the screws as follows:
If on-length screws A,B are adjusted |
For longer on-length, readjust screws A,B |
to match this system: |

NOTE: This thermostat does not have a setting for steam/gravity air. Cycles would not be long enough for accurate temperature control.
IMPORTANT
When using a high efficiency furnace such as a 90% or greater AFUE (Average Fuel Utilization Efficiency) unit, adjust screw A out one turn and screw B in.

Refer to masking tape labels you placed on wires when you removed your old thermostat.
■ Match the letter of your old thermostat wire with the terminal of the corresponding letter on the back of your new thermostat. Refer to figures on pages 22-23 and Table 2 for typical wire colors for easy matching. Hold the thermostat as shown to minimize need for wire extenders. If wires are still
too short, use wire connectors (purchase locally) to extend wires. See figure (left)
for guidelines on using wire extenders.
■ In 5-wire installations only, be sure to remove the factoryinstalled jumper connecting terminals R and Rc .
