The universal Aprilaire Model 8476 Thermostat is an easy-to-use programmable thermostat that offers customizable control over your home's temperature and air freshness for total comfort and efficiency.
  • Allows you to clean your air on your terms: Event-Based™ Air Cleaning circulates air throughout your home periodically throughout the day or for a specific period of time to provide greater comfort through cleaner air and more even temperatures.
  • Helps you save on energy costs: Set back the temperature overnight and when you're away. According to the U.S. Environmental Protection Agency, a programmable thermostat can save you up to 30% on energy costs annually.
  • Features progressive recovery: This ensures your home is always at your desired temperature by activating the heating and cooling equipment prior to a scheduled setting.
