How to Program a Honeywell Programmable Thermostat

Honeywell programmable thermostats are a great way to reduce your home's heating and cooling bills. The thermostats can be set for different temperatures throughout the day based on your routine. Once you know how to program your Honeywell programmable thermostat, you can program the system to not operate as much when you are away from home. Honeywell pre-programs all of their programmable models to Energy Star program settings.

Step 1

Press the "Clock" button on the lower part of the touch screen to set the time. Use the directional arrow on the upper left-hand side of the thermostat display to advance the time of day. Press the up arrow and hold the button to advance the time quickly. When the time is set, press the "Done" button on the lower right-hand side of the thermostat.

Step 2

Set the day of the week, press the "System" button on the right side of the Honeywell programmable thermostat. The display will show five blank buttons at the bottom of the screen. Press the center blank button. The display is now ready to set the date using the directional buttons on the upper right.

Step 3

Select the "System" button until the proper function displays that you want to program. The heat, cooling and auto display will come up with each press of the "System" button. Most people use the "Auto" function so the thermostat will turn the heat or air conditioning on based on temperature. You would press the "System" button three times to bring up the "Auto" display.

Step 4

Program your weekly settings to your personal schedule. The thermostat will show the current Energy Star settings that the thermostat is currently set to. To change a setting, press "Schedule" and then the "Edit" button on the lower portion of the touch screen.

Step 5

Press the day of the week on the upper portion of the screen to select the day you want to change. Press the "Wake" button and use the directional buttons to schedule the time and temperature setting for this time period.

Step 6

Press the other time period buttons to schedule the time and temperature for each. There is a "Leave", "Return" and "Sleep" setting for the daily schedule. Press the "Done" button to save and exit the programming mode.
