The most common mistake people make with programmable or smart thermostats is using the 'Hold' button. It's the 'Off' switch for your efficiency.
When you press 'Hold', you're telling the thermostat to ignore its carefully crafted schedule and stay at one temperature forever. This effectively turns your $200 smart device into a 1970s dial. The key to energy savings is allowing the temperature to fluctuate throughout the day based on your presence. If you're cold, use the 'Temporary Override' or 'Up Next' feature, which will return to the schedule automatically after a few hours.
Trust the schedule you've built! Let the house cool down when you're at work and warm up before you arrive. Using the system as designed can save you up to $180 a year compared to a 'permanent hold' lifestyle. It's a mental shift as much as a technical one. Break the 'Hold' habit and let your house breathe with you!
