Complete Control Over Indoor Air Quality

Maintain precise control over your indoor home environment more easily with the AprilAire Universal Wi-Fi Touchscreen Thermostat with Humidity or Ventilation Control. Featuring AprilAire's automatic event based cleaning, this WiFi-connected thermostat is designed to balance all aspects of indoor air quality, including Temperature, Humidity, Air Purity and Fresh Air. The balance is struck by an array of intelligent features, such as automatic ventilation, a convenient "Heat Blast" function, and many others. Choose how you want to control the air quality of your home and enjoy the additional features AprilAire's thermostat has to offer:

  • Wi-Fi accessible thermostat with 7-day programmability
  • Full integration with Amazon Alexa voice control (optional)
  • Change settings locally, online, or with the free mobile app
  • Event-Based Air Cleaning automates ventilation for fresh air
  • "Heat Blast" rapidly raises a room's temperature by 3°F to 5°F.
  • Large, backlit touchscreen is easy to read day and night
  • Universal design works with 2H/2C or 4H/2C heat pumps

The AprilAire Wi-Fi Thermostat App, available free for iOS and Android devices, syncs with the thermostat to provide seamless control whether you make changes at the thermostat, through your online account, or through the app. Features disabled from the thermostat are also automatically removed from the app.

Prep Your Home for Scheduled Events with Intelligent Automation

The AprilAire Wi-Fi Thermostat not only offers standard 7-day programming, but also a "progressive recovery" feature that can activate your heating or cooling equipment BEFORE a scheduled event, so that when it's time for the event to start, your home has already reached your desired temperature.

Program the thermostat, for example, to remember what time you arrive home from work, and it can automatically prep the house before you reach your front door.

Keep the Air Fresh with Automatic Ventilation

Many new homes are required to have proper ventilation to ensure that fresh air can easily be pumped in from outside, and the AprilAire Wi-Fi thermostat meets this requirement. The thermostat provides automatic ventilation when it detects specific environmental conditions in your home. You can set parameters that trigger ventilation, and/or take advantage of AprilAire's unique "Event-Based Air Cleaning", which allows you to automate ventilation based on special circumstances, such as cooking time in the kitchen, or party time in the living room.
