Product Info


The Aprilaire Home Comfort Control is for homeowners who want total comfort and control over all aspects of indoor air quality. As the most comprehensive controller Aprilaire offers, the Model 8910 Home Comfort Control goes beyond simple temperature management to include humidity, air purity and air freshness control. All of these indoor air essentials come into perfect balance with one, easy-to-operate touchscreen control.
When paired with Aprilaire whole-home air quality solutions, the intuitive Aprilaire Model 8910 Home Comfort Control gives you total control of your comfort.
  • Control Humidity: The Model 8910 automatically controls your Aprilaire humidification system and dehumidification system and provides confirmation that proper humidification is taking place.
  • Control Air Purity: The Model 8910 controls your Aprilaire air purifier, allowing you to manage air purity when you need it with Event-Based Air Cleaning, and provides easy-to-read confirmation that your air is being cleaned based on your preferences.
  • Control Fresh Air: The Model 8910 controls your Aprilaire ventilation system, providing fresh air automatically or when it is needed, and confirms when fresh air is being provided.
  • Control Temperature: The programmable Model 8910 controls heating and cooling equipment to maintain comfort while saving energy and provides immediate comfort from the cold with the Heat Blast®.

Event-Based Air Cleaning
When paired with an Aprilaire whole-home air purifier, the Aprilaire Model 8910 Home Comfort Control allows you to clean your home's air on your terms with Event-Based Air Cleaning. This is perfect for allergy and asthma sufferers and for times when your air is more contaminated than usual-for example, when pollen counts are high or you're churning up dust when vacuuming.
Event-Based Air Cleaning includes four options for purifying your air: Constant Clean runs 24/7, Automatic runs for a minimum of 30 minutes every hour, Event Clean runs for three hours, and Allergy runs for 24 hours and then returns to the most recent mode

Energy Savings, Comfort and Convenience
According to the U.S. Environmental Protection Agency, a programmable thermostat can save you up to 30% on energy costs annually.
The Aprilaire Model 8910 Home Comfort Control is easy to program and helps you save money on energy costs by allowing you to set back the temperature during the night or when you're away. Multiple hold options maximize comfort and energy savings:
  • Vacation hold
  • Custom-timed hold
  • Permanent hold
  • Temporary hold

Digital Touchscreen Control
Large 10.3 square-inch touchscreen featuring an exclusive message center that makes programming and setup effortless. It provides real-language instructions and information - no codes to remember, no manual to reference. The Model 8910 also tells you exactly what your equipment is doing.
