STEP THREE: Make Add-On Air Proving Decision
In addition to monitoring system power and fan regulation, TrueSTEAM can monitor physical air movement
through an optional add-on air proving device. If an air proving device is added, TrueSTEAM can create steam
only if the fan is moving air through the supply duct.
Note: This image is not a complete wiring diagram. It only depicts add-on air proving.
See "Wiring the TrueSTEAM" on page 19.

HVAC System
R and C with an air proving device in-line
on C.

TrueSTEAM. Set DIP 5 up and keep
DIP 4 down.
• TrueSTEAM will look for physical air
movement through its C connection before
steam enters the duct.
