WIRING–GETTING STARTEDDRAIN CONNECTION
BEFORE YOU GET STARTED
TrueSTEAM wiring is different from evaporative pad humidifier wiring. TrueSTEAM is able to
monitorsystempower,andregulatesystemfanoperation,inadditiontosolenoidwatervalve
actuation. These wiring features are configured by DIP settings.
DIP 3 = Wireless operation (applicable only on wireless models)
If DOWN (default) wireless terminal is disabled.
IfUP,wirelessterminalisenabled.
DIP 4 = Power monitoring.
IfDOWN(default),TrueSTEAMlooksforRinputbefore
allowing humidity.
IfUP,TrueSTEAMdoesnotlookforRinputbeforeallowing
humidity. Power is still allowed to pass through if R is wired.
DIP 5 = Back-up air proving.
IfDOWN(default),TrueSTEAMdoesnotlookforair
movement (via air proving device) before allowing humidity.
IfUP,TrueSTEAM looks for air movement (via air proving
device) before allowing humidity. Wire an air proving device
between TrueSTEAM C and System C.
