Take Full Control of Indoor Temperature and Air Quality

Control virtually any HVAC or heat pump system with the AprilAire S86WMUPR Programmable Wi-Fi Multi-Stage Universal Thermostat with IAQ Control. This Wi-Fi connected thermostat provides a capacitive touch interface to command multistage HVAC, heat pump, and humidifier/dehumidifier systems. A colorful 2.4" display clearly presents indoor temperature and humidity, with the option for adding a wired external sensor to monitor outdoor temperature. AprilAire's IAQ (Indoor Air Quality) Control allows the thermostat to focus on a specific aspect of your home's environment, humidifiers, dehumidifiers, or whole-home ventilation, to ensure a high standard of health and comfort while conserving energy and preserving home furnishings and electronics. An array of additional intelligent features compliment the thermostat's modern design, including programmable temperature schedules, Progressive Recovery for pre-heating/pre-cooling prior to scheduled temperature setpoints, and HeatBlast function for rapid heating within a short period of time.

Prep Your Home for Scheduled Events with Intelligent Automation

This AprilAire Thermostat offers standard daily and weekly schedule programming, allowing users to set various customized temperature setpoints throughout the week according to their desires and unique schedules.

The "Progressive Recovery" feature activates 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 the thermostat will bring the house to the desired temperature before you reach your front door.

Similar to the Progressive Recovery feature, this AprilAire Thermostat includes a HeatBlast feature, which fully activates your heating system, including dual fuel systems, to raise indoor temperatures between 3 °F to 5°F within a relatively short period of time.

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 this 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.

AprilAire Care AppAprilAire Wi-Fi Thermostat App
