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:
S
humidification mode has been enabled, and
S
the unit is in HEAT mode, and
S
humidification demand exists (24V present at H), and
S
DISPLAY mode indicates humidification is OFF.
S
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)].
S
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:
S
humidification mode has been enabled, and
S
the unit is in HEAT mode, and
S
humidification demand exists (24V present at H).
