Step 1. Set Current Time and Day
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. a. Press  once.
The time is displayed (Fig. 17).
b. Press and hold   or   until the cur-
rent time is displayed.Fig. 17. 
c. Press  again.
The day is displayed (Fig. 18).
d. Press and hold   or
  until the cur-
rent day is displayed.Fig. 18. 
e. Press  once.
The current time and day and the current tempera-
ture are displayed (Fig. 19).Fig. 19.

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. Program Period Description When Available

Verify that your cooling system works
IMPORTANT:
 To avoid damaging the compressor in the air conditioner, do not operate the cooling system when the tem-
perature outdoors is below 50°F (10°C).
OPERATION

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.
Replace Batteries
As the batteries run low, your thermostat shows the following in the digital display:
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. Switch Setting Result
Fan Auto A single-speed fan turns on automatically with the air conditioner or furnace.
A two-speed fan usually runs on high with the air conditioner and on low with the furnace. 
Auto is the normal setting for most homes.
On The fan runs continuously. Use this setting for improved air circulation during special 
occasions or for more efficient air cleaning. 
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.
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. 
						

							69-1631—1 20d. 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.
Override program settings
NOTE: Make sure the System switch is set to either HEAT or COOL before making any changes to the schedule.
Change the temperature temporarily
Press     or      until the desired temperature is 
displayed. An arrow is displayed, indicating that the change is 
temporary (Fig. 27).
NOTE: A temporary change to temperature lasts for current 
program period only. Heating/cooling schedule you 
programmed resumes when next scheduled pro-
gram period is reached.To cancel temporary 
change before next scheduled program period, 
press .Fig. 27.
