ComfortDisc Thermostats





  • Easy to read-vibrant, soft blue backlighting with a large display allows the 8570 to be viewed at any light level.
  • Real energy savings-the 8570 is Energy Star Rated and offers "setback" programming that minimizes energy consumption while you are sleeping or away from home. The Aprilaire Model 8570 Thermostat adjusts your home's temperature up to four times a day for any combination of days, or every day individually.
  • Friendly programming-easily view or change the program schedule on a single screen. You can even program the fan to be "On" or "Automatic" during each event of the program.
  • Constant comfort- after setting back your thermostat at night to save energy, your morning temperature setting is assured at the precise time you wish, through the use of special Progressive Recovery technology. This is accomplished while optimizing your heating and cooling system's start time for total energy efficiency. For example, if you want to reach a specific temperature in your home by 7 AM, the system will begin operating at just the right amount of time before 7 AM to reach the set temperature.
  • Holiday feature-allows the 8570 program to be overridden until the date and time you select-whether you're away for hours, days or weeks.
  • Exceptional convenience- the Aprilaire Model 8570 Thermostat maintains the program and all application settings with its permanent program memory even during power outages of any length. The 8570 will also notify you when you need to change an air filter, service a humidifier, or service your heating, ventilation, and air conditioning (HVAC) equipment. The monitor can also conveniently display your HVAC dealer's name and phone number if you need assistance.
  • Real energy savings-"setback" programming minimizes energy consumption while you are sleeping or away from home. The 8400 Series Programmable Thermostats adjust your home's temperature up to four times each day and also separate weekdays from weekends.
