Efficiency
Getting the Most from Your Programmable Thermostat
6 min read••
Most programmable thermostats never get programmed. Here's how to use yours effectively.
Studies show many programmable thermostats stay on default settings. Here's how to actually save money with yours.
The Basic Strategy
Set It and (Mostly) Forget It The point of programming is automation. Create schedules that match your routine, then let the thermostat work.
Don't Override Constantly Every time you override the program, you reduce savings. If you're overriding daily, adjust the program instead.
Effective Setback Strategies
When You're Away Set back temperature by 5-10°F while at work. - Summer: Raise cooling setpoint - Winter: Lower heating setpoint
When You're Sleeping Similar setbacks while sleeping usually work well: - Summer: Slightly warmer at night (ceiling fan helps) - Winter: Cooler at night (extra blankets cost nothing)
Avoid Extreme Setbacks Setting way back saves little more than moderate setbacks but: - Takes longer to recover - May cause discomfort when returning - Stresses equipment more
Sample Schedules
Working Household (M-F) **Summer:** - 6 AM: 76°F (wake-up cool down) - 8 AM: 82°F (leave for work) - 4 PM: 76°F (pre-cool for return) - 10 PM: 78°F (sleeping)
**Winter:** - 6 AM: 68°F (wake-up warm-up) - 8 AM: 62°F (leave for work) - 4 PM: 68°F (pre-heat for return) - 10 PM: 64°F (sleeping)
Work From Home Smaller setbacks when you leave, but still program for sleeping hours.
Common Mistakes
Programming Too Cold/Hot When Away Extreme setbacks don't proportionally increase savings but do stress your system.
Not Adjusting Seasonally Your schedule may change with seasons. Update accordingly.

Smart Thermostat Advantages
If your thermostat can learn or detect occupancy: - Let it optimize based on actual patterns - Use geofencing features - Review energy reports for insights
