APPLICATION
HE440A, HE480A Steam Power Humidifiers use a thermal fan
interlock control to provide whole house humidification on
demand. A two-stage water treatment system keeps the
reservoir clean, maintains operation and reduces mainten-
ance. Steam power humidifiers work with furnaces, heat
pumps, setback thermostats and virtually any Honeywell
humidity control. Use the Honeywell H1008 Automatic
Humidity Control for optimal performance.
