Step-By-Step Guide: How to Program Your Thermostat
The following steps work for most standard programmable thermostats, including models by Honeywell:
1. Set the Time and Date
Before programming any settings, make sure your thermostat displays the correct time and date. This ensures the scheduled changes happen at the right moments.
2. Choose the “Program” or “Schedule” Mode
Locate the program or schedule option on your thermostat, typically accessible via the menu or a dedicated button.
3. Set Your Wake Time
Start with your morning routine. Set the temperature for when you wake up. In summer, aim for a cooler temperature. In winter, keep it comfortable without overheating.
4. Set Your Leave Time
If no one is home during the day, adjust the temperature to conserve energy. Raise the temp in summer and lower it in winter to reduce HVAC usage while the house is empty.
5. Set Your Return Time
Program your desired temperature for when you usually return home. Your system will kick in early enough to make the home comfortable when you walk in the door.
6. Set Your Sleep Time
Adjust the temperature for overnight comfort. Most people sleep better in cooler conditions, so consider setting your AC or heat a few degrees lower at night.
7. Repeat for Weekends
Many thermostats allow separate weekday and weekend settings. If your weekend routine differs, be sure to customize accordingly.
Recommended Temperature Settings
If you’re unsure where to start, try these energy-efficient guidelines from the U.S. Department of Energy:
Summer
- When home: 78°F
- Away: 85°F
- Sleeping: 74–76°F (or lower, depending on comfort)
Winter
- When home: 68°F
- Away: 60–62°F
- Sleeping: 65–66°F
These settings can help reduce your energy usage without sacrificing comfort. Even adjusting by just 1–2 degrees can make a noticeable difference on your utility bill.
Programming your thermostat is one of the simplest ways to boost home comfort and lower energy costs—but only if it’s done right. If you’re unsure about your current setup or want to explore smarter, more efficient options, the team at Associated Heating and Air Conditioning is here to help.
