Types of Thermostats: Know Your Device

Before you can program your thermostat effectively, you need to know what type you have. Here’s a breakdown of the most common models:

Manual Thermostats

These basic models require physical adjustment each time you want to change the temperature. While they can’t be programmed in the traditional sense, I’ll share some manual adjustment tips later in this article.

Programmable Thermostats

These allow you to set temperature schedules for different times of day and different days of the week. They typically fall into three categories:

• 7-day models: Allow unique programming for each day of the week
• 5+2-day models: Allow one schedule for weekdays and another for weekends
• 5-1-1 models: Allow one schedule for weekdays, and separate schedules for Saturday and Sunday

Smart Thermostats

These Wi-Fi connected devices offer the most flexibility, learning your preferences over time and allowing remote control via smartphone apps. Popular brands include Nest, Ecobee, and Honeywell.

DIY Tips for Thermostat Placement

Before diving into programming, let’s ensure your thermostat is positioned correctly. Improper placement can lead to false readings and inefficient operation.

Optimal Placement Tips:

• Install on an interior wall, away from direct sunlight, drafts, doorways, windows, and furniture
• Position about 5 feet above the floor, where air circulation is good
• Keep away from air vents, radiators, and other heating/cooling sources
• Avoid areas that receive unusual amounts of sun (which can trigger cooling) or shade (which can trigger heating)
• Don’t place near kitchens or bathrooms where temperature fluctuations are common

If your thermostat is poorly positioned, consider relocating it as a worthwhile DIY project. This simple change could significantly improve your HVAC system’s efficiency.

Seasonal Programming Recommendations

Different seasons require different approaches to thermostat programming. Here are energy-efficient temperature recommendations by season:

Winter Programming Tips

• When you’re home and awake: 68°F (20°C)
• When you’re asleep or away: 60-65°F (15-18°C)

Summer Programming Tips

• When you’re home and awake: 78°F (25°C)
• When you’re asleep or away: 82-85°F (28-29°C)

Remember, each degree of adjustment can save approximately 2% on your energy bill. Finding your personal comfort zone within these ranges is key to balancing savings with comfort.

Many homeowners wonder whether they should completely turn off their HVAC system when away. Complete shutdown isn’t recommended for periods less than 24 hours. Instead, use temperature setbacks of 7-10 degrees, which saves energy while preventing your home from becoming too hot or cold.

Step-by-Step Guide to Programming Your Thermostat

Now, let’s get into the practical DIY steps for programming different types of thermostats.

Basic Programmable Thermostat Programming

1. Start by setting the correct time and day
   • This is crucial for your schedule to work properly
   • Don’t forget to adjust for daylight saving time changes
2. Plan your schedule before programming
   • Identify when you typically wake up, leave home, return home, and go to bed
   • Consider creating a simple chart to visualize your routine
3. Access the programming menu
   • Usually done by pressing a “Prog,” “Schedule,” or similarly labeled button
   • Follow manufacturer instructions for your specific model
4. Set your weekday schedule
   • Program the wake-up time and desired temperature
   • Program the daytime (away) time and temperature
   • Program the evening (return) time and temperature
   • Program the sleep time and temperature
5. Set your weekend schedule
   • Follow the same process, adjusting times and temperatures to match weekend routines
   • Many people stay home more on weekends, so your away periods might be shorter or nonexistent
6. Review your program
   • Most thermostats allow you to review the entire schedule
   • Double-check all times and temperatures for accuracy
7. Activate the program
   • Look for a “Run,” “Start,” or similar button
   • Some thermostats begin running the program automatically after you exit the programming mode

Smart Thermostat Programming Tips

If you have a smart thermostat, the programming process will differ slightly:

1. Complete the initial setup
   • Connect to your home Wi-Fi network
   • Download the corresponding smartphone app
   • Create an account if necessary
2. Use the app for programming
   • Most smart thermostats are easier to program through their apps than on the device itself
   • Follow the guided setup process, which typically includes setting your preferred temperatures and schedule
3. Enable learning features
   • Many smart thermostats have learning capabilities
   • During the first week, make manual adjustments when needed
   • The thermostat will learn your preferences and eventually create an optimized schedule
4. Set up geofencing
   • This feature uses your smartphone’s location to adjust temperatures when you leave or approach home
   • Enable this in the app settings for additional energy savings
5. Review and adjust automation
   • After a few weeks, review how the automated settings are working
   • Make adjustments as needed based on comfort and energy usage reports

Advanced DIY Programming Tips for Maximum Savings

Take your thermostat programming to the next level with these advanced DIY tips:

1. Use Temperature Setbacks Strategically

Instead of maintaining a constant temperature, program significant setbacks when you’re away or asleep. A setback of 8-10 degrees for at least 8 hours can yield substantial savings.

Contrary to popular belief, it’s not better to keep a constant temperature. This is a common myth. Your HVAC system uses less energy to reheat or recool your home than it does to maintain a constant comfortable temperature when no one is home.

2. Consider Your Home’s Thermal Mass

Homes with greater thermal mass (like brick or concrete construction) retain heat longer and cool down more slowly. For these homes, shorter setback periods might be more effective than longer ones.

3. Account for “Recovery Time”

Modern programmable thermostats have a “recovery” feature that calculates how long it takes to reach your desired temperature. This allows them to turn on heating or cooling in advance, so your home reaches the target temperature exactly when programmed.

If your thermostat lacks this feature, you’ll need to manually account for recovery time by adjusting your schedule accordingly.

4. Optimize for Time-of-Use Utility Rates

If your utility company charges different rates depending on the time of day (peak vs. off-peak hours), program your thermostat to minimize energy use during high-rate periods.

5. Create Vacation Settings

Most programmable and all smart thermostats allow for vacation or “away” modes. Use these to maintain minimal heating or cooling while you’re gone for extended periods.

6. Use Fan-Only Mode

Program your system to use the fan-only mode during mild weather. This circulates air without activating heating or cooling, reducing energy consumption while maintaining comfort.

7. Schedule Regular Reviews

Review your schedule seasonally (four times per year) and whenever your household routine changes significantly, such as starting a new job or school schedule. This ensures your programming remains optimized for your current lifestyle.

Practical DIY Tips for Specific Living Situations

Different living situations call for different programming approaches. Here are tips tailored to various scenarios:
