Improve Indoor Air Quality Using Your HVAC System

Control virtually any HVAC or heat pump system with the AprilAire S86NMUPR Programmable Multistage Universal Thermostat with IAQ Control. This 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.

  • Programmable thermostat with 24/7-day programmability
  • Universal design works with 2H/2C or 4H/2C HVAC or heat pump systems
  • Integrates with 1 Indoor Air Quality Control (IAQ) system: Humidifier, Dehumidifier, or Ventilation
  • Colorful 2.4" display clearly presents indoor temperature and humidity
  • Real Language Setup simplifies installation and daily use
  • Progressive Recovery feature meets temperature setpoint before next scheduled temperature event
  • HeatBlast feature quickly raises indoor temperature by 3°F to 5°F
  • Optional connection to wired sensor (8052) to detect and report outdoor temperature

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.
