Honeywell Steam Humidifier - Deciding on the Wiring Configuration; Make Power Monitoring Decision

WIRING
Steam humidier wiring is different from evaporative pad humidier wiring. In addition to solenoid water valve
actuation, steam humidier can monitor system power and regulate system fan operation.
You need to decide on the congurations you will use before wiring the steam humidier, These decisions will
affect how the connections are made, how the DIP switches are set, and how steam humidier operates for the
homeowner.
STEP ONE: Make Power Monitoring Decision
Power Monitoring is a conguration that allows steam humidier to humidify only when it has conrmation that
the HVAC system transformer has power. This helps prevent steam from entering the supply duct when the HVAC
system is not operating. There are two ways to congure power monitoring, depending on the humidity
control used:
• CONFIGURATION 1 – Using a thermostat with integrated humidity control
• CONFIGURATION 2 – Using a humidistat separate from the thermostat
Before making decisions about wiring congurations:
I understand when to use the DIP switches and how to set them for the humidity control.
CONFIGURATION 1 — using a thermostat
with an integrated humidity control such as
VisionPRO IAQ or Prestige — is ideal for
contractors who:
Want simplied wiring – steam humidier
only needs to be connected to the HUM
terminals from the control.
Provide integrated system and accessory
control in the living space.
Are using VisionPRO IAQ or
Prestige thermostat.

CONFIGURATION 2 — using a humidistat
separate from the thermostat such as H6062
or TrueIAQ — is ideal for contractors who:
Use a humidity control separate from
the thermostat.
Wish to locate the humidity control on the
return duct.
