How Humidification Mode Works
DISPLAY, BASIC AND PRECISION
—These modes allow user
control of relative humidity between 15 and 45%. These conditions
must be met for either mode to operate:
humidification mode has been enabled, and
the unit is in HEAT mode, and
humidification demand exists (24V present at H), and
DISPLAY
mode indicates humidification is OFF.
BASIC
mode mode also requires presence of heating de
mand [Y for HP heat, or W for gas heat (W may be energized
with G de-energized)].
PRECISION
—(Available only if Wi-Fi is operational or out
door sensor is attached)
Basic Dew Point Control
adjustment mode will change the humidi
fication set point based on the outdoor temperature and a user-
defined dew point adjustment setting.
Precision Dew Point Control
adjustment mode will operate when
these conditions are met:
humidification mode has been enabled, and
the unit is in HEAT mode, and
humidification demand exists (24V present at H).
