APPLICATION
HE440A Steam Power Humidifier uses 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 maintenance. Steam
power humidifiers work with furnaces, heat pumps, setback
thermostats and virtually any Honeywell humidity control.
Use Honeywell H1008 Automatic Humidity Control for optimal
performance.
