Step 1. Prepare for installation  
a. Carefully unpack your new thermostat. Save your receipt and make sure you have the following parts:  
Thermostat and mounting plate  
Labels  
Screws and anchors  
Installation and Programming Instructions  
b. Gather the needed tools and supplies listed below.  
Required tools and supplies  
Optional tools  
Two AA alkaline batteries. Honeywell recommends Energizer®  
batteries.  
Wire cutter/stripper or sharp knife  
Level  
Screwdriver  
Electrical tape  
Hand or power drill with 3/16-inch or 7/32-inch drill bit  
Pencil  
c. Make sure that your heating and cooling systems are working properly. If there is a problem with either system, call a  
heating/air conditioning contractorthe problem may persist after you install the new thermostat.  
IMPORTANT: To avoid damaging the compressor in the air conditioner, do not operate the cooling system when the  
temperature outdoors is below 50°F (10°C).

Step 2. Remove the old thermostat  
Fig. 2  
a. Turn off power to the heating/cooling system, either at the  
furnace or at the fuse/circuit breaker panel.  
b. Remove the cover of your old thermostat (Fig. 2).  
c. Unscrew and remove the old thermostats mounting plate from  
the wall, but do not disconnect the wires.  
d. Inspect the old thermostat wiring. If the wiring meets any of  
the following conditions, see the special wiring  
instructions on page 9.  
M20140  
The old thermostat is a clock thermostat with wires attached  
Fig. 3  
to the C or C1 terminals.  
The old thermostat has 6 or more wires, excluding wires  
attached to C or C1 terminals.  
The old thermostat has 3 wires.  
There are 5 wires connected to the old thermostat.  
There are extra wires that are not connected to the old  
thermostat.  
e. Using the enclosed labels, mark the wires with the letter of the  
terminal that it is attached to on the old thermostat (Fig. 3). Do  
not label the wires by color.  
M19086  
If the labels do not match the letters on the old thermostat  
terminals, see the wiring cross reference table on page 10.

WALL OPENING  
f. Disconnect the wires from the old thermostat and wrap the  
wires around a pencil to keep them from falling back into the  
wall.  
Note: Remember, if your old thermostat contains mercury, you  
must recycle it. See page 2 for more recycling information.

Step 3. Install the mounting plate  
Fig. 5  
a. Separate the mounting plate from the thermostat using a coin,  
as shown in Fig 5.  
b. Position the mounting plate on the wall. Be sure the mounting  
plate sits flush against the wall and none of the wires are  
trapped behind it.  
c. Level the mounting plate and use a pencil to mark the center of  
the mounting plates screw holes.  
M20139  
d. Remove the mounting plate and drill holes at the locations you  
marked.  
For drywall, drill two 3/16 inch holes.  
For plaster or wood, drill two 7/32 inch holes.  
Fig. 6  
e. If installing in drywall, gently tap the anchors that were provided  
into the drilled holes until they are flush with the wall.  
f. Reposition the mounting plate over the holes, pull the wires  
through the wiring opening, and loosely insert the mounting  
screws into each of the drilled holes or anchors (Fig. 6).  
g. Make sure the mounting plate is level and tighten the mounting  
screws.

Special wiring instructions  
A clock thermostat with C or C1 terminals  
A clock thermostat has one or two extra wires attached to the C or C1 terminals that allow the clock to operate. These  
wires are not used during the installation of your new 3200 thermostat and must be insulated from each other to avoid  
damaging your electrical circuit.  
a. Make sure that power to the heating/cooling system is turned off.  
b. Locate the wires that are connected to the clock terminals marked C or C1.  
c. As you disconnect the wires, do not allow these wires to touch.  
d. Wrap the wires separately, using electrical tape to insulate the wires.  
e. Place the wires where they will not interfere with the operation of the new thermostat.  
You will not connect these wires to your 3200 thermostat.  
f. Continue with the installation as instructed on page 4 at step 2e.  
Six or more wires  
If your old thermostat has six or more wires (excluding clock wires attached to the C or C1 terminals), your heating/cooling  
system is most likely a variation of a heat pump or multistage system. Your 3200 thermostat will NOT work with such  
systems and should be returned to the place of purchase. See the compatibility table on page 2 for information about which  
programmable thermostat WILL work with your system.  
Three thermostat wires  
If you have three wires for heating only and can operate the fan using the fan ON switch, the 3200 thermostat will work with  
your system. Continue the installation procedure on page 4, step 2e.  
If you have a three-wire heating-only system and cannot operate the fan using the fan ON switch, the 3200 thermostat will  
probably NOT work with your system. Contact your heating contractor for installation assistance.  
Wires that are not connected to the old thermostat  
If there are extra wires that do not connect to your old thermostat, do not label them. You will not connect these wires to  
your new thermostat. Tape off the wires with electrical tape and place them where they will not interfere with the operation  
of the new thermostat. Continue the installation procedure on page 4, step 2e.

Five wires connected to the old thermostat  
Your new thermostat has a factory-installed metal jumper between the R and Rc terminals (Fig. 15). Remove the jumper

Step 2. Learn about the programming features  
Your 3200 thermostat allows you to program schedules for both a heating season and a cooling season.  
During the heating season, you will want to set the normal room temperature higher and the energy-saving  
temperature lower.  
The reverse is true during the cooling seasonthe normal room temperature will be lower and the energy-saving  
temperature higher.  
For each season, you can set up to four program periods for the weekdays (MondayFriday), and up to two program  
periods for the weekends (Saturday and Sunday). The program periods are defined on the next page.

Programming tips  
You do not need to program times and temperatures for all program periods.  
If you decide not to program your thermostat, it will automatically control heating at 68°F (20°C), and cooling at 78°F  
(26°C), 24 hours a day.  
If you decide not to program weekend schedules, the temperature that is programmed for the weekday SLEEP  
schedule will remain in effect until the next program period, which begins on Monday morning.  
The temperatures cannot be set any higher than 88°F (31°C) or any lower than 45°F (7°C).  
When pressing the buttons, use the ball of your finger or a soft pencil eraser. Use of sharp fingernails or pencil points  
can damage the keypad.  
If you make an error at any time during programming, press  
period where you left off.

Make sure that the positive and negative terminals are oriented correctly as marked inside the battery case.  
Note: If you insert the new batteries within 2030 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 and you will have to

IMPORTANT: Replace the batteries once a year to prevent the heating/cooling system from shutting down due to lack of  
battery power in the thermostat. If you are leaving home for longer than a month, change the batteries before leaving to  
prevent the system from shutting down due to lack of power.
