a thermal fan interlock control to provide humidification for
the whole house. The steam power humidifier is designed to
work with high efficiency furnaces, heat pumps and set back
thermostats. The humidifiers work with virtually any
Honeywell humidity control, but use the Honeywell Perfect
Climate Comfort Center™ control for optimal performance.
