HUMIDIFIER OPERATION
The Intelligent Zoned Comfort System works with your Aprilaire Automatic Humidifier Control (AHC) to enhance the performance of your whole house humidifier.
The HUM LED on the control will turn on when the humidifier is operating. Humidification, using a whole house humidifier, can only occur when the heat is on, or when the fan has been set to operate continuously (FAN ON shown on the thermostat). Your Intelligent Zoned Comfort System can also keep the fan running if the humidification need has not been met. If the AHC senses that humidification is still required when the heating system is about to turn off, the Intelligent Zoned Comfort System will keep your fan operating until the need is met, or for 15 minutes. To prevent rapid cycling of your HVAC equipment, the blower will be operated for no less than 5 minutes.
