Honeywell is a well-known manufacturer of residential and commercial climate control systems. Honeywell offers user programmable thermostats that can be used to operate combined heating and air conditioning systems. Setting up your Honeywell thermostat and programming it for the first time can seem a little intimidating. Luckily, the process is simpler than it appears, and by following the step-by-step instructions, you can have your Honeywell thermostat ready to go in just minutes.
Program the current date into your Honeywell thermostat. Note the month indicator on the left side of the digital display screen. Press the "Up" or "Down" arrow buttons until the desired month is shown, then press "Next." Use the same buttons to adjust the day indicator until the desired day is shown; press "Next." Use the same process to set the year and then press "Done." A digital clock will appear on the display screen.
Program the thermostat clock to reflect the correct current time. Adjust the clock's hours and minutes digits using the "Up" and "Down" arrow buttons. Press "Done" when the desired time is displayed.
Note the three buttons positioned below the digital display screen; press and release the far left button, also known as the "Systems" button. Hold down the centre button for approximately five seconds or until the display screen changes; press "Next."
Specify your heating and cooling system type. Press the "Up" or "Down" arrow buttons until the desired option is highlighted. Choose between "Heat/Cool," "Heat Pump," "Heat Only," "Heat Only with Fan," "Hot Water Heat Only" or "Cool Only." Press "Next" to select the highlighted option.
Set the heating fan control for your Honeywell thermostat. Use the "Up" or "Down" arrow buttons to highlight the appropriate heating fan control option; choose between "Gas or Oil Heat" and "Electric Heat." Press the "Next" button. Specify your heating system when setting the heating cycle rate for your thermostat. Highlight the desired option, choosing from "Gas or Oil Furnace," "Electric Furnace," "Hot Water or High-Efficiency Furnace," "Gas/Oil Steam" or "Gravity System." Press "Next."
Set the manual or auto changeover function. Highlight the "Automatic Changeover" option if you want the thermostat to switch between the Heat, Cool and Off modes based on the temperature of the room. Choose the "Manual Changeover" option if you want to have control of when the thermostat changes modes. Press the "Next" button to confirm your selection and advance to the next screen.
Program the temperature format and Daylight Savings Time functions for your thermostat. Press the "Up" or "Down" arrow buttons to highlight the "Fahrenheit" or "Celsius" temperature format; press "Next" to make your selection. Use the same process to turn Daylight Savings Time On or Off and press "Next."
Set the system setting for your Honeywell thermostat. Press the "System" button until the desired option is shown on the display screen. Choose between "Heat," "Cool" and "Off."
Choose a fan setting for the thermostat. Press the "System" button to access the fan setting mode. Press the "System" button again to set the fan to "Auto" if you want it to run only when the heating or cooling system is on. Press the "System" button one more time to set the fan to "On" if you want it to run continuously.
Program your heating and cooling schedule; the schedule is divided into "Wake," "Leave," "Return" and "Sleep" segments. Press the "Next" button. Press "Next" a second time to edit the schedule; Monday through Friday will flash on the display screen. Press the "Systems" button to select the days whose schedules you want to change. Press "Next." The "Wake" schedule will appear on the digital display screen. Use the "Up" and "Down" arrow buttons to adjust the heating and cooling temperatures as desired; press "Next." Use the same process to program the "Leave," "Return" and "Sleep" segments.
Use the same process described in the "Program Thermostat" section, Step 3 to change the heating and cooling schedule for Saturday and Sunday.
