5 69-1631—1 Step 3. Install 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 mount- ing plate is 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 cen- ter of the mounting plate screw holes. d. 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. Fig. 6. e. If installing in drywall, gently tap the anchors (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. Fig. 7. ✓ Check your progress The mounting plate is now mounted on the wall and should look like Fig. 7.

69-1631—1 6 Step 4. Set Thermostat for Your Type of Heating System I M P O R T A N T : 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. a. 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. b. 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 Heat- ing 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. c. The thermostat is set to display the temperature in degrees Fahrenheit (°F). If you want to display the tem- perature in degrees Celsius (°C), turn DIP Switch 3 to Off position. d. 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. Fig. 8.

9 69-1631—1 Step 7. Install the batteries 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. 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 do not interfere with the operation of the new thermostat. You will not connect these wires to your 3200 Thermostat. f. Continue with the installation.Fig. 13. Fig. 14. IMPORTANT: Batteries must be installed for programming and operation of the thermostat and heating/cooling system. Honeywell rec- ommends using Energizer® batteries. a. Make sure that the System switch is set in the OFF position. b. Using a coin, open the battery door as shown in Fig. 13. c. Install the batteries. Make sure that the positive and nega- tive terminals are oriented correctly as marked inside the battery case. d. Replace the battery door. e. 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 Programming section. M1719C REMOVING BATTERY DOOR
69-1631—1 10 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 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. 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. M20127 JUMPER (FACTORY- INSTALLED).
