When the Blower Activation switch is in the OFF position,
the humidifier control will only operate the humidifier
if humidity is required and the HVAC system fan is
operating or the HVAC system is producing heat.
AUTOMATIC DIGITAL HUMIDIFIER CONTROL
Your Automatic Digital Humidifier Control works in
conjunction with your heating, ventilation, and air
conditioning (HVAC) equipment to control the operation
of the humidifier. In order to operate in automatic mode,
the included outdoor temperature sensor (ODT) must
be installed. The control senses indoor humidity, and
the ODT senses outdoor temperature. The control then
automatically adjusts the operation of the humidifier to
provide the optimal humidity level for the home.
The digital display on the automatic control accurately
shows the humidity level inside the cold air return duct.
It will provide the best reflection of the humidity in the
living space when the HVAC blower is operating.

Your AprilAire
humidifier control
is installed in the
cold air return duct.
During the first
heating season,
your humidifier
control needs to
be set initially to
match your home's
condition. Please
follow these steps
when adjusting
your control
(refer to FIGURE 1)�
1. Turn the dial setting knob to 5, which is within the
normal range. During the next 24 to 48 hours it may
be necessary to adjust the dial for more or less
humidity, depending on your personal comfort and
home's requirements. Refer to TABLE 3 – Operation
Guide�
2. During the coldest portion of the first heating
season, minor adjustments may be necessary. This
is dependent upon your home's construction. Refer
to TABLE 3 – Operation Guide�
The humidity in your home will now be accurately
controlled to meet your needs and should not need
further adjustment during future heating seasons. Make
note of the dial setting in the event you temporarily
move the knob to OFF when performing annual
maintenance of your AprilAire humidifier.
