The quality of indoor air is purported to be several times more harmful than what's just outside, so the Aprilaire 8920W WiFi Thermostat is designed to correct this.
Rather than simply controlling the heating and cooling, the thermostat works to control the humidity of the air and how fresh it is. When the fresh air setting is activated, the system will provide fresh air into the home for added comfort. To manage the air quality, the Aprilaire 8920W WiFi Thermostat features an air purification setting to remove harmful airborne particles from the atmosphere.
The WiFi functionality built-in the device allows users to program the unit, activate event-based cycles like air cleaning and keep track of the home environment while out of the house.
