SEQUENCE OF OPERATION
The dehumidifier will automatically “sample” the air by
turning on its blower (and the HVAC blower if this option
has been wired – see WIRING INTERNAL CONTROL
above), and measuring the relative humidity (RH) once
every hour. Sampling will also occur when the RH setting
is lowered using the or buttons on the control.
During sampling, if the RH of the air is above the
setting the dehumidifier, the compressor will turn on.
The compressor, dehumidifier blower and HVAC system
blower (if on) turns off when the RH of the air is 3% RH
below the setting.

EXTERNAL CONTROL
The external control (i.e. Aprilaire Model 76 Dehumidifier
Control, Model 8620 Thermostat or Model 8910 Home
Comfort Control) must have a normally open (NO – all
Aprilaire controls are normally open type) or normally closed
(NC) dry contact output, and must be installed in the space
that is going to be dehumidified. Select the type of control
using the NO/NC dip switch on the dehumidifier control.
SEQUENCE OF OPERATION
When the external control calls for dehumidification, the
dehumidifier blower and HVAC blower (if this option has been
wired – see WIRING EXTERNAL CONTROL above) turn on,
then three seconds later the compressor turns on. All will turn
off when the external control stops calling for dehumidification.

SET UP THE DEHUMIDIFIER FOR REMOTE CONTROL
After wiring the Model 76 to the dehumidifier as shown, use the power switch
located on the outlet panel of the dehumidifier to power up the dehumidifier. The
dehumidifier control should display OFF.
1. Enter the Installer Set-Up menu by pressing and holding the MODE button on the
dehumidifier control for 3 seconds; REMOTE DISABLED will appear on the display.
2. Press the or button to select REMOTE ENABLED.
3. Press the MODE button again to complete set up (DONE will appear on the
display).
SEQUENCE OF OPERATION
The Model 76 Dehumidifier Control can be installed in any convenient location within
the living space while the dehumidifier is installed in the space that is going to be
dehumidified such as a crawl space, attic or basement. The relative humidity (RH)
displayed on the Model 76 is the RH in the space where the dehumidifier is located
– the dehumidifier communicates this to the Model 76. Changes to the dew point
setting (1 = less dry, 7 = more dry) are made at the Model 76 and communicated
to the dehumidifier. The dehumidifier can be turned on and off using the ON/OFF
buttons of the Model 76.
Once every hour the dehumidifier will turn on its blower and sample the air in the
zone to be dehumidified (sampling will also occur whenever the dew point setting
is raised). If the dew point of the air is higher than the setting on the control, the
dehumidifier compressor will turn on. When the dew point of the air is below the
setting on the Model 76 Control, the dehumidifier will turn off.
When the Model 76 Control is wired to the dehumidifier in this application and after
completing the set up (see SET UP THE DEHUMIDIFIER FOR REMOTE CONTROL
above), REMOTE will appear on the display of the dehumidifier control.

SEQUENCE OF OPERATION
Adjust the relative humidity (RH) setting on the dehumidifier control; this will be the
setting for both the Primary and Secondary Zone. Once an hour, the dehumidifier
will “sample” the air in the Primary Zone. If there is no need for dehumidification in
the Primary Zone the dehumidifier will then sample the air in the Secondary Zone.
When sampling in the Primary Zone the dehumidifier will energize the dampers and
then turn on its blower (and the HVAC System blower if wired as shown in WIRING
INTERNAL CONTROL above), to measure the RH of the air. If the RH of the air is
above the setting, the compressor will turn on. If the Primary Zone does not need
dehumidification, the dampers are de-energized and the HVAC System Blower (if on)
is turned off while the dehumidifier blower continues to run to sample the air in the
Secondary Zone. If the RH of the air in the Secondary Zone is above the setting, the
compressor will turn on.
SET UP THE DEHUMIDIFIER FOR ZONING
1. With OFF showing on the control, press the MODE button for 3 seconds to enter
the Installer Set Up menu.
2. Press the MODE button until ZONE DISABLED appears.
3. Press the or button to change to ZONE ENABLED.
4. Press the MODE button repeatedly until DONE shows on the display.

Note: Dehumidifier zoning is not recommended in zoned HVAC applications.
PARTS NEEDED (ADDITIONAL PARTS MAY BE REQUIRED)
• Model E080/E100/E130
• Model 76, Model 8620 or Model 8910 control
• Insulated duct
• Thermostat wire
• Duct fittings & hardware
• 20A outlet (E130 only)
• Drain pan and float switch (if required)

• 5442 Damper Kit (includes: 2 - 10" dia N.O.
dampers, 2 -10" dia N.C. dampers and one
40VA, 24VAC plug-in transformer)
SEQUENCE OF OPERATION
The external control (i.e. Model 76 Control or Model 8910 Home Comfort Control)
provides on-demand control of the dehumidifier for the Primary Zone. When the
Primary Zone calls for dehumidification, the dehumidifier energizes the dampers,
and turns on its blower and compressor. The dehumidifier will also turn on the HVAC
System Blower if wired as shown in WIRING EXTERNAL CONTROL IN PRIMARY ZONE
above. The Primary Zone demand will override an existing Secondary Zone demand.
The Secondary Zone is controlled by the relative humidity (RH) setting at the
dehumidifier control. Once an hour, or immediately after dehumidifying the primary
zone, the dehumidifier will “sample” the air in the Secondary Zone. When sampling,
the dampers are not energized while the dehumidifier blower runs and the RH is
measured. If the RH is above the setting on the control, the compressor will turn on
and the Secondary Zone will be dehumidified.
SET UP THE DEHUMIDIFIER FOR ZONING AND EXTERNAL CONTROL
1. Press the MODE button for 3 seconds to enter the Installer Set Up menu
2. Press the MODE button until ZONE DISABLED appears.
3. Press the or button to change to ZONE ENABLED.
4. Press the MODE button again to show EXTERNAL DISABLED.

USING THE DEHUMIDIFIER TO PRE-CONDITION THE VENTILATION AIR
The dehumidifier can be used to remove moisture from the ventilation air before
it is delivered to the home. Install the ventilation duct to the dehumidifier inlet
duct as shown in FIGURE 2. The control on the dehumidifier must be used for the
Primary Zone (i.e. an external control cannot be used) in this installation. If the RH
of the incoming air is above the setting on the control the air will be dehumidified.
Install a ventilation duct with a normally closed Model 6506 damper to the return duct of the HVAC system (see FIGURE 1) and wire the dehumidifier
to the HVAC system as shown in

ATION WIRING. The outdoor temperature (ODT) sensor is used to limit ventilation if the outdoor temperature
gets too hot or too cold (see SET UP THE DEHUMIDIFIER F
O% V !$
ATION below). If temperature limits are not needed, the ODT sensor does
not have to be installed. Follow the set up instructions below and set the number of minutes per hour that ventilation will be needed (refer to the
Installation Manual for details on determining how much ventilation is needed). Whenever the heating or cooling turns on, or when the dehumidifier
turns on, the dehumidifier will open the damper and bring in fresh outdoor air. If the equipment doesn’t run for the set number of minutes, the
dehumidifier will turn on HVAC fan at the end of the hour to ensure ventilation needs are met.
