Aprilaire Programmable Thermostat
A work of art that works for you.

The slim profile, ultra-sleek Aprilaire Model 8570 Thermostat does more than just look great. It offers unsurpassed performance and premium features.

Easiest to Operate
This consumer tested and proven thermostat features simple, menu-driven programming. Simply highlight "Menu Options" on the display and press "Select." You view the entire daily schedule on one screen as you make changes. And the Model 8570 automatically adjusts for daylight saving time.

Exceptional Convenience
The Model 8570 provides maintenance alerts for key system accessories, including Aprilaire Humidifiers and Air Cleaners, and tells you when service is needed. Your dealer's contact information can even be displayed at the touch of a button, and when properly equipped, the Model 8570 also displays outdoor temperature and indoor relative humidity.

Friendly Programming
Easily view or change the program schedule on a single screen. Select to program every day individually, weekdays separately from weekends or every day the same. You can even program the fan to be "On" or "Automatic" during each event of the program. The program is permanently stored even in a power outage.

Information at Your Fingertips
Simply select the "info" setting, and when connected to an Aprilaire Automatic Humidifier, information such as outdoor temperature and indoor relative humidity can be viewed.

Simple Maintenance
Monitors alert you when service is needed, conveniently displaying your dealer's name and phone number.

Save Money
Holiday (vacation) hold allows the thermostat program to be overridden until you determined return date and time. Whether you're away for hours, days or weeks, you save energy and money and return to a comfortable home.
