AprilAire 8840 Automation Thermostat, 7" Color Touchscreen, WiFi, IAQ Control

HD Color Touchscreen For Intelligent HVAC Control

Offering improved design over the previous 8830 model, the AprilAire 8840 Automation Thermostat, 7" Color Touchscreen, WiFi, IAQ Control offers all the same great features plus a beautiful 7-inch HD color touchscreen. No longer limited to black and white, this full-color AprilAire IAQ thermostat upgrade is a sight to see and the perfect addition to a modern home.

The AprilAire IAQ thermostat is capable of controlling nearly any type of HVAC unit, including humidifiers and even whole-home dehumidifiers, while offering support for external sensors (one included). Featuring the unique "SmartIAQ" solution by AprilAire, this advanced Internet-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 and a convenient "Heat Blast" function, among many others.

• Wi-Fi accessible thermostat with 7-day programmability
• 7-inch backlit HD color touchscreen is easy to read day and night
• Change settings locally, online, or with the free mobile app
• Includes optional remote sensor to display outdoor temperature
• Event-Based Air Cleaning automates ventilation for fresh air
• "Heat Blast" makes cold air easy to heat up fast
• Universal design works with 3H/3C 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.
