How do I know which model to buy?

  2. Ensure that your choice is right for your home’s cooling and heating systems.
  3. Always select a model that offers many different day programming options such as:
  • 7-Day programming – Homeowners who have busy schedules find this option useful as it allows them multiple individual daily programs.
  • 5-1-1-Day – This is a good option for homeowners who need separate programs for Saturdays and Sundays, as well as multiple weekday options.
  • 5-2-Day – Homeowners who require separate programming for weekends and weekdays prefer this option.
  • 1 Week – This option allows for numerous weekly programs.

How do I properly dispose of my old thermostat?
