Step 1. Prepare for Installation

1. 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
2. Gather the needed tools and supplies listed below.
   

   Required Tools and Supplies	Optional Tools
   •      Two AA alkaline batteries. Honeywell recommends Energizer® batteries. •      Screwdriver. •      Hand or power drill with 3/16-inch or 7/32-inch drill bit. •      Pencil.	•      Wire cutter/stripper or sharp knife. •      Level. •      Electrical tape.

3. Make sure that your heating and cooling systems are working properly. If there is a problem with either system, call a heating/air conditioning contractor—the 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).

Remove Old Thermostat

1. Turn off power to the heating/cooling system, either at the furnace or at the fuse/circuit breaker panel.
2. Remove the cover of your old thermostat (Fig. 2).
3. Unscrew and remove the old thermostat’s mounting plate from the wall, but do not disconnect the wires.
4. Inspect the old thermostat wiring. If wiring meets any of the following conditions, see special wiring instructions section after Step 7.
   • The old thermostat is a clock thermostat with wires attached to the C or C1 terminals.
   • The old thermostat has six or more wires, excluding wires attached to C or C1 terminals.
   • The old thermostat has three wires.
   • There are five wires connected to the old thermostat.
   • There are extra wires that are not connected to the old thermostat.
5. Using enclosed labels, mark wires with the letter of the terminal it is attached to on the old thermostat (Fig. 3). Do not label using colors. If labels do not match letters on old thermostat terminals, see the wiring cross-reference table in the Special Wiring Instructions section.
6. 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 Mercury Notice for more recycling information
   ✓Check your progress
   Your wall should now look like Fig. 4.

Step 3. Install Mounting Plate

• Separate the mounting plate from the thermostat using a coin, as shown in Fig 5.
• Position the mounting plate on the wall. Be sure the mounting plate is flush against the wall and none of the wires are trapped behind it.
• Level the mounting plate and use a pencil to mark the center of the mounting plate screw holes.
• Remove the mounting plate and drill holes at the locations marked.
  • For drywall, drill two 3/16-inch holes.
  • For plaster or wood, drill two 7/32-inch holes.
• If installing in drywall, gently tap the anchors (provided) into the drilled holes until they are flush with the wall.
• 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).
• Make sure the mounting plate is level and tighten the mounting screws.
  Check your progress
  The mounting plate is now mounted on the wall and should look like Fig. 7.

Step 4. Set Thermostat for Your Type of Heating System

IMPORTANT:
Setting your thermostat correctly for your type of heating system allows it to maintain accurate temperature control, minimize swings in the temperature of the room, and efficiently run the fan.

1. Use the FUEL SWITCH on the back of the thermostat to set your new thermostat for the type of fuel that your heating system uses: F– gas or oil, or E–electric.
   NOTE: This setting enables proper fan operation.
2. Use DIP switches 1 and 2 on the back of the thermostat to set your new thermostat for your type of heating system. See the Heating System Table on the next page to find the correct settings.
   NOTE: These DIP switches are factory-set for a warm air, gas, or oil heating system.
3. The thermostat is set to display the temperature in degrees Fahrenheit (°F). If you want to display the temperature in degrees Celsius (°C), turn DIP Switch 3 to the Off position.
4. You can install the batteries and program your thermostat now, or you can wait until the thermostat is mounted on the wall. To install the batteries, see Step 7. To program the thermostat, see the Programming section.

Heating System Table

Type of System	DIP Switches 1 and 2	Fuel Switch
Warm air, gas, or oil heating system with an efficiency rating under 90%. (The furnace efficiency rating should be on the furnace.)	Use factory setting 1–On; 2–On	F
High-efficiency furnace such as a 90% or greater AFUE (Average Fuel Utilization Efficiency) unit	1–Off; 2–On	F
Hot water boiler	1–Off; 2–On	F
Electric furnace	1–On; 2–Off	E

Step 5. Wire Thermostat Terminals

1. Hold thermostat as shown in Fig. 9.
2. Using the labels on the wires, match letter of your old thermostat wire with the corresponding terminal on the back of your new thermostat.
   NOTE: If letters on old thermostat terminals do not match letters on new thermostat terminals, all old wires may not need connecting to the new thermostats. See Special Wiring Instructions section.
3. Loosen terminal screws and slip each wire beneath its matching terminal (Fig 10).
4. Securely tighten terminals.

Step 6. Mount Thermostat

1. Align the tabs at the top of the thermostat with the tabs at the top of the mounting plate (Fig. 11).
2. Press the lower edge of the case to latch the bottom of the thermostat (Fig. 12)

Step 7. Install the batteries

IMPORTANT:
Batteries must be installed for the programming and operation of the thermostat and heating/cooling system. Honeywell recommends using Energizer® batteries.

1. Make sure that the System switch is set in the OFF position.
2. Using a coin, open the battery door as shown in Fig. 13.
3. Install the batteries. Make sure that the positive and negative terminals are oriented correctly as marked inside the battery case.
4. Replace the battery door.
5. Remove the clear plastic label from the digital display.
   Check your progress
   When the batteries are installed correctly, the digital display flashes all entries once, then begins to flash a default time and the current temperature (Fig. 14). The flashing continues until you begin to program the thermostat. You are now ready to program the thermostat.
   See the Programming section.

Special Wiring Instructions

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.

1. Make sure that power to the heating/cooling system is turned off.
2. Locate the wires that are connected to the clock terminals marked C or C1.
3. As you disconnect the wires, do not allow these wires to touch.
4. wrap the wires separately, using electrical tape to insulate the wires.
5. Place the wires where they do not interfere with the operation of the new thermostat.
   You will not connect these wires to your 3200 Thermostat.
6. Continue with the installation.

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 thermostat compatibility table for information about which programmable thermostats 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. 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 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 individually with electrical tape and place them where they will not interfere with the operation of the new thermostat. Continue the installation procedure.
Five wires connected to old thermostat
Your new thermostat has a factory-installed metal jumper between the R and Rc terminals (Fig. 15). Remove the jumper before wiring the R and Rc terminals.

Thermostat C Terminal
This thermostat does not use the C wiring terminal.

Old thermostat terminals that do not match new thermostat terminals
Use the table below to wire the new thermostat.

Old Thermostat Terminal	Connect to New Thermostat Terminal	Description
R, RH, 4, V	R*	Power
Rc, R	Rc*	Power for cooling

2. Step 2. Learn About 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 season—the 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 (Monday–Friday), and up to two program periods for the weekends (Saturday and Sunday). The program periods are defined in the following table.

     Program Period	Description	When Available
     WAKE	The time when you get up and get ready to leave your home. You can set the system at a comfortable temperature for this period.	Weekdays and weekend
     LEAVE	The time when you are regularly away from home. You can set up an energy-saving temperature for this period.	Weekdays only
     RETURN	The time between returning home and going to bed. You can set the system at a comfortable temperature for this period.	Weekdays only
     SLEEP	The time when you are sleeping. You can set up an energy-saving temperature for this period.	Weekdays and weekend

Programming Tips

• You do not need to program times and temperatures for all program periods.
  If you decide not to program your thermostat, it automatically controls 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 remains 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. Using sharp fingernails or pencil points can damage the keypad.
• If you make an error at any time during programming, press. Then press until you reach the program period you last programmed.
