Programming your thermostat lets you maximize comfort and savings by setting temperature changes according to your schedule. Program your thermostat if it is newly installed, or if you want to change temperature or schedule settings for heating or cooling. Programming allows you to decide what time the heat comes on on Saturday morning, for instance, and how warm you want it. For Honeywell 6000-series thermostat models TH6110, TH6220, or TH6320 (check for model number under the battery holder), the instructions are the same.
Press "Set Clock/Day/Schedule," then use "Up" and "Down" arrows to the right of the screen to set the correct time. Press "Set Day," then press the "Up" or "Down" arrows to select the correct day of the week. Press "Done" to save these settings.

Press "Fan" (repeat as necessary) to select "Auto" (fan runs only when the heating or cooling system is on), or "On" if you want the fan to run continuously. (These options may vary depending on your heating/cooling system.)
Choose "Select System Setting" to match your home. These settings tell your thermostat which systems to control. Options may vary, depending on your heating/cooling components and specific thermostat model. "Heat" has the thermostat control only the heating system. "Cool" has the thermostat control only the cooling system. By selecting "Auto," the thermostat automatically controls heating or cooling, depending on the indoor temperature. In "Off," the thermostat signals all systems to stay off. If your heat pump has an auxiliary heating mode, "Em Heat" tells the thermostat to lock out the compressor, and controls emergency and auxiliary heat.
Program your schedules to arrange heating and cooling according to your weekly schedule, optimizing both comfort and economy. Be sure the thermostat is set to "Heat" or "Cool," depending on what you want to program. Press "Set Clock/Day/Schedule," then press "Set Schedule." Press the "Up" or "Down" arrows to the right of the screen to set your "Weekday Wake" time (Monday through Friday); press "Next." Press the "Up" or "Down" arrows to set the temperature for this time period, then press "Next;" the thermostat switches to the next time period. Use the "Up" and "Down" arrows to set the time and temperature for the time you "Leave" (for work); press "Next." Use the "Up" and "Down" arrows to set the start times and temps for the other two weekday time periods ("Return" and "Sleep"). Press "Next." Repeat to set weekend (Saturday and Sunday) times and temperatures, then press "Done" to save and exit.
Press the "Up" or "Down" arrows (whenever you want to temporarily override the temperature setting) until the "Heat (or "Cold") Setting" on the screen shows the temperature you want. This immediately changes the temperature setting until the next programmed time period begins. To cancel this override, press "Cancel."
Finish the step you are on if, or when you make a mistake. You may suddenly realize that you programmed the wrong temperature for the wrong time or day. When this happens, continue programming through to the end of the setup step you are working on. All the information you entered is saved as you go, so at the end of the step just cycle back through and review or correct any wrong numbers.
TH6000-series thermostats come pre-programmed, so you should only have to worry about details like when the house should be warm or cool. You can find all these options in the illustrated Operating Manual included with the thermostat, or get it using the link in the Reference section.
Wiring a thermostat wrong could damage it or your heating/cooling system. Honeywell recommends that only a trained, experienced technician should install a TH6000-series thermostat. If you have that skill and expertise, you need the more technical Installation Guide, which shows wiring for different heating/cooling combinations.
The Installation Guide also describes how to set up or change basic parameters like Fahrenheit/Celsius temperature display, and compressor cycle rates.
