INSTALLATION
Verify You Have Correct Thermostat
Make sure that the CT3200 is the correct thermostat for your heating/cooling system. Read the compatibility chart
below to determine which system you have. If your system is not compatible with the CT3200, the table recommends
an alternate Honeywell model. If you are unsure what type of thermostat is right for your system, visit us on the Web at
www.honeywell.com/yourhome or call Honeywell Customer Care at 1-800-468-1502.

✓ 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.
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.

Step 1. Set Current Time and Day
• 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.
13 69-1631—1
Program Period Description When Available
WAKE The time when you get up and get ready to leave your home. You can Weekdays and weekend
set the system at a comfortable temperature for this period.
LEAVE The time when you are regularly away from home. You can set up an Weekdays only
energy-saving temperature for this period.
RETURN The time between returning home and going to bed. You can set the Weekdays only
system at a comfortable temperature for this period.
SLEEP The time when you are sleeping. You can set up an energy-saving Weekdays and weekend
temperature for this period.
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.

Set Fan and System Switches
The switches on the bottom of the thermostat faceplate control the operation of your fan and the heating and cooling
system. Set the Fan switch first and then set the System switch.
NOTE: In a heat-only system, the fan runs continuously only if the fan wire has been con-
nected to the G terminal on the back of the thermostat.
System Cool The thermostat controls your air conditioning system.
Off Both the heating and air conditioning systems are off.
Heat The thermostat controls your heating system.
Replace Batteries
As the batteries run low, your thermostat shows the following in the digital display:
If you see: Batteries are: You should:
Flashing “bAt Lo” Low Replace the batteries as soon as possible, within the month.
Blank display Dead Replace the batteries immediately. Your heating/cooling system is not
operating.
a. Make sure that the System switch is set to the OFF position.
b. Open the battery door.
c. Press on the left side of the batteries to remove them.
NOTE: If new batteries are inserted within 20-30 seconds of removing old ones, reprogramming is not
needed. If display is blank, batteries are dead or incorrectly installed and reprogramming is needed.
19 69-1631—1
d. Install new batteries. Make sure that positive and negative terminals are oriented as marked inside battery
case.
e. Close the battery door and set the System switch to HEAT or COOL.
NOTE: If “bAt Lo” continues to display after replacing the batteries, set System switch to OFF, insert batteries back-
ward, wait for five to ten seconds, and return batteries to correct orientation. Then reprogram.
IMPORTANT:
Replace batteries once a year to prevent heating/cooling system from shutting down due to lack of battery
power in thermostat. If leaving home for longer than a month, change batteries before leaving.
