Aprilaire 56 Operating Instructions

TO DETERMINE THE RELATIVE HUMIDITY
(RH) IN YOUR HOME
The Humidifier Control is a precision instrument that can be used
to determine the RH accurately in your home. If you would like to
determine the relative humidity in your home, follow these steps:
1. Activate the furnace blower by setting your thermostat fan
switch to the ON position, or by setting your thermostat to a
higher temperature.
2. Turn the control dial setting to the OFF position. Then, slowly
turn the dial clockwise until you hear the solenoid valve "click
on". Next, slowly turn the dial counterclockwise until you hear
the solenoid valve "click off". This will be very close to the
actual RH in your home.
CHECK THE HUMIDIFIER OPERATION
(BOTH AUTOMATIC AND MANUAL MODES)
Set the knob to TEST/RESET. Make sure that the water shutoff
valve is open and that there is electricity to the unit. The furnace
blower motor must be operating for the humidifier to function.
After the humidifier has operated for one minute and water is
entering the unit and coming out at the drain, reset the control to
it's original setting.
CHANGE WATER PANEL LIGHT
(BOTH AUTOMATIC AND MANUAL MODES)
If the Change Water Panel
WATER PANEL CHANGE INDICATOR
light remains lit, your
Water Panel needs to be
replaced. After changing
the humidifier pad, turn the
knob to TEST/RESET until the
Change Water Panel light
starts to blink. NOTE: Control
must be powered (furnace
on) to reset the Water Panel
change indicator.
If the Change Water Panel light is blinking, your unit is in TEST
mode. Do not leave in TEST mode or humidifier will not operate.
Turn the knob to it's original setting for normal operation.

OPERATING INSTRUCTIONS
Model 56
Automatic Humidifier Control
YOUR HUMIDIFIER
Your Humidifier Control offers two modes of operation, Automatic or
Manual. The automatic mode of operation requires the installation
of an outdoor sensor and provides the following benefits:
1. You always receive the optimal amount of humidity.
Automatically adjusts your home's relative humidity (RH)
based on the outdoor temperature.
2. Eliminates the need to manually adjust the control when
outdoor temperature changes – a common occurrence with
manual humidistats.
3. Maximizes the amount of time humidity is maintained in
the healthy range, 40-60% RH. Precisely adjusts the relative
humidity to deter the adverse effects of low humidity on your
home's occupants, such as itchy eyes and dry skin. It also
protects your home and its furnishings from the effects of excess
condensation when outdoor conditions are the most severe.
4. Simple operation with few adjustments.
Eliminates the need to turn the dial setting
to OFF during the summer season.
