Honeywell Steam Humidifier - Make Add-On Air Proving Decision

WIRING
STEP THREE: Make Add-On Air Proving Decision
In addition to monitoring system power and fan regulation, steam humidier can monitor physical air movement
through an optional add-on air proving device. If an air proving device is added, steam humidier can create steam
only if the fan is moving air through the supply duct.
Honeywell HIGHLY recommends adding an Add-On Air Proving Device for ALL Steam
Humidier installations.
IMPORTANT NOTE: The image below is not a complete wiring diagram. It only depicts power monitoring
and is not meant to be a stand alone diagram. Please refer to the “Wiring the steam humidier” section in the
following pages for complete wiring diagrams.
WIRING BASICS
• Wire steam humidier R and C to HVAC
system R and C with an air proving device
in-line on C.
• Congure air proving through DIP 5 on
steam humidier. Set DIP 5 up and keep
DIP 4 down.
• Steam humidier will look for physical air
movement through its C connection before
steam enters the duct.
