Application Sheet 6 – Using the Ventilation Feature of the Dehumidifier
Parts needed for ventilation:
__ Model 6506 damper
__ Model 8052 Outdoor
Temperature Sensor
(optional)
__ Model 4010 10VA
Transformer
__ 6” Insulated Duct, fittings
and hardware
__ Intake Hood
__ Thermostat wire
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 Figure 2. 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 for Ventilation
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.

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 3. 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.

Set Up the Dehumidifier for Ventilation
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 “VENT DISABLED” appears.
3. Press the Up or Down button to change to “VENT ENABLED”.
4. Press the Mode button and “VENT TIMED” will be displayed. Press the Up or Down button to toggle between:
TIMED: no temperature limits
AUTO – B: Ventilation not allowed if ODT > 100°F or ODT < 0°F; allowed only when heating if 0°F < ODT < 20°.
AUTO – C: Ventilation not allowed if ODT > 100°F or ODT < 0°F
AUTO – D: Ventilation not allowed if ODT > 90°F; allowed only when heating if 0°F < ODT < 40°F
5. Press the Mode button, the use the Up and Down buttons to set the Vent Time (minutes/hour).
6. Press Mode repeatedly until “DONE” appears on the display.
