HE420A STEAM POWER HUMIDIFIER OPERATING YOUR HUMIDIFIER The HE420A Honeywell Humidifier is controlled by an Automatic Humidity Control. The Automatic Humidity Control is mounted in the return air duct where it can be exposed to the air stream of the return air and is designed to automatically adjust the humidity level based on indoor temperature and humidity, inferred or measured outdoor temperature, and the dial setting.
HE420A STEAM POWER HUMIDIFIER HOW YOUR HUMIDIFIER WORKS Your Honeywell humidifier uses the principle that hot water creates moist air and as the moist air circulates, the relative humidity rises.
