Honeywell Thermostat Settings Explained:

As the #1 HVAC company in Lansing, HVAC Lansing Pros is here to help you understand your Honeywell thermostat and keep your system running efficiently all year round.

🔧 Quick Overview: What Are the Best Honeywell Thermostat Settings?Here’s a quick summary of ideal thermostat settings for comfort and savings:
  • Summer Cooling: 76–78°F when home, 82–85°F when away
  • Winter Heating: 68–70°F when home, 62–65°F when away
  • Fan Mode: Use “Auto” for efficiency; “On” for continuous air circulation
  • Schedule Settings: Customize daily for weekdays/weekends or set once with smart models
  • Eco Mode: Optimizes energy use while maintaining comfort
  • Hold Function: Temporarily overrides the schedule until you resume or reset
Let’s dive deeper into each setting and when to use them.

1. 🌡️ Temperature Setpoints: Heating & CoolingThe temperature setpoint is what you program your thermostat to maintain. Honeywell thermostats allow you to set different temperatures for different times of day.
Recommended Settings:
  • Summer (Cooling):
    • Daytime (when home): 76–78°F
    • Away from home: 82–85°F
  • Winter (Heating):
    • Daytime (when home): 68–70°F
    • Away/sleeping: 62–65°F
💡 Pro Tip: Every degree you raise your AC or lower your heat can save you 1–3% on your energy bill.

2. 📆 Schedule ProgrammingProgrammable Honeywell thermostats let you set time-based schedules so your HVAC system adjusts automatically. Most models support:
  • 5-2 schedules (Weekday/Weekend)
  • 7-day schedules (Custom daily)
  • Smart schedules (based on usage, motion sensors, or geofencing)

3. 💨 Fan Settings: Auto vs OnYour Honeywell thermostat has two primary fan settings:
  • Auto: The fan runs only when heating or cooling is active. Best for energy savings.
  • On: The fan runs continuously, regardless of temperature. Best for even airflow and air purification.
🌀 Why “Auto” is Usually Better in Lansing Homes:
Michigan’s climate fluctuates seasonally. “Auto” prevents unnecessary fan use in mild spring/fall temperatures, keeping energy bills lower.

4. 🔁 System ModesYour thermostat will have 3–5 mode options depending on the model:
  • Cool: Activates air conditioning
  • Heat: Activates heating system
  • Off: Turns HVAC system off
  • Auto (Changeover): Automatically switches between heating and cooling as needed
  • Emergency Heat: For heat pump systems only—uses electric resistance backup heat
💡 Tip: In transitional seasons like fall or spring in Lansing, use Auto Mode to maintain comfort without manually switching.

5. 🔒 Hold and Temporary OverrideThe Hold feature is a manual override for scheduled settings.
  • Temporary Hold: Keeps the new setting until the next programmed change
  • Permanent Hold: Maintains the setting until manually canceled
🛠️ Example:
If your programmed setting is 76°F but you want it at 72°F for a few hours, select "Temporary Hold" and it will reset at the next schedule point.

6. 🌱 Eco Mode / Energy SaverSome Honeywell thermostats offer Eco Mode, which slightly adjusts your comfort settings to reduce energy use.
  • Adjusts heating or cooling by 2–4°F
  • Saves energy without a noticeable drop in comfort
  • Great for weekends away or low-use areas
Enable Eco Mode through the menu or Honeywell app.

7. 📱 Wi-Fi and Smart Honeywell ThermostatsModels like the Honeywell T9, T10, or Lyric offer:
  • Remote control via Honeywell Home App
  • Voice control (Amazon Alexa, Google Assistant)
  • Room-by-room temperature control (T9+ sensors)
  • Energy usage reports
✅ If you're not sure which model you have, check under the faceplate or consult the Honeywell thermostat model checker.
