2.
Pull the loose black, white and green wires out from the wire compartment (additional
wires will be present). Install an approved electrical connector to the wire compartment
cover (not included). Run a black (hot), white (neutral), and a green or bare ground wire
from the supply through the electrical connector. Connect all wires from the supply
to their corresponding wires within the wire compartment
(Figure 6)
. Use approved
methods for all connections.
3.
Carefully tuck wires back inside wire compartment and replace wire compartment cover
securing with the screw that was removed earlier.
SECTION 5
Setting the Speed
1.
Determine the CFM required. The unit
can be set from 40 CFM to 120 CFM
in increments of 10 CFM. Remove the
screw securing the access panel cover in
place and open the cover to gain access.
Locate the speed control panel inside the
unit
(Figure 9).
2.
For setting of 40 CFM to 60 CFM:
Place
the rocker switch in the “Low” position
and the first dial in the “Lower” position
then set the second dial to the required
CFM
(Figure 10).
3.
For settings of 70 CFM to 90 CFM:
Place the rocker switch in the “Low”
position and set the first dial to the
required CFM
(Figure 10).
4.
For settings of 100 CFM to 120 CFM:
Place the rocker switch in the “High”
position and set the top dial to the
required CFM
(Figure 10).
SECTION 6
Optional Air Filter
An air filter (available separately) can be added
to this unit to provide additional filtration of the
intake air. The unit will accept a 10” x 10” x 2”
filter. To install:
NOTE:
Adding an air filter will decrease the
airflow of the unit. You will need to increase
the CFM selected in
SECTION 6
to account for
the decreased air flow. Filters must be changed regularly. Refer to the filter manufacturer’s
recommendations to determine how often the filter should be changed.
1.
Remove the screw securing the access panel cover in place and open the cover to gain
access to the controls and filter area.
2.
Ensure the filter is facing the correct way and slide the filter into the slot in the housing.
Make sure the filter is seated all the way to the bottom of the housing
(Figure 11).
3.
Close the access panel and reinstall the screw holding the access panel in place.

SECTION 7
Completing the Installation
NOTE:
When fan is mounted inline and no penetration is made into unconditioned spaces, there
is no need to use a sealant appropriate for contact with the building materials present and for
the temperature requirements of the installation to prevent air leakage from unconditioned
spaces. Additional material (backing rod, ceiling material) are also not required.
1.
Close the access panel and reinstall the screw holding the access panel in place.
2.
Restore power and test your installation.
SECTION 8
Setting the Controller
The unit mounted controller monitors temperature and humidity of incoming air and allows the
installer to configure optimal ventilation.
With power to the unit turned on, the initial screen will show “OFF”. Press the “ON” button to
show the current temperature and humidity condition. By pressing the “ON” button, the unit
will turn on for continuous air flow using the CFM settings from
SECTION 6

ENERGY SAVING MODE
NOTE:
This unit is equipped with an Energy Saving Mode that allows you to configure upper
and lower limits for temperature and humidity. By setting these limits, you will help prevent
extreme temperature or humidity changes from entering into the living space.
1.
If you have not already pressed the “ON” button in step one of this section, do so now.
Press the “CONFIGURE” button once and the display will show a “C” and “Temp Unit” on
the right hand side.
2.
Press the up or down button to display the temperature in Fahrenheit or Celsius.
3.
Press the “CONFIGURE” button again to set the upper limit temperature. This is the
temperature that when the outside air coming into the home exceeds, the fan will stop
and enter sampling mode. You will see “Upper Limit” and “Temperature” on the right
hand side. Use the “UP” and “DOWN” buttons to adjust the temperature.
4.
Press the “CONFIGURE” button again to set the upper limit humidity level. This is the
humidity level that when the outside air coming into the home exceeds, the fan will stop
and enter sampling mode. You will see “Upper Limit” and “Humidity” on the right hand
side. Use the “UP” and “DOWN” buttons to adjust the temperature.
5.
Press the “CONFIGURE” button again to set the lower temperature level. This is the
temperature that when the outside air coming into the home falls below, the fan will
stop and enter sampling mode. You will see “Lower Limit” and “Temperature” on the
right hand side. Use the “UP” and “DOWN” buttons to adjust the temperature.
6.
Press the “CONFIGURE” button again to set the lower limit humidity level. This is the humidity
level that when the outside air coming into the home falls below, the fan will stop and enter
sampling mode. You will see “Lower Limit” and “Humidity” on the right hand side. Use the
“UP” and “DOWN” buttons to adjust the temperature. Setting this to 0 or “LO” will override
the humidity set level. This may be necessary in very low humidity areas of the country.
7.
Press the “CONFIGURE” button until it returns to the main screen. You will see “ON” in
the top left corner of the display. At this point, the information has been stored.
SECTION 9
Using the Controller
1.
Energy Savings Mode:
To enter the Energy Savings mode, press the “ON/OFF/ENERGY
SAVINGS” Button until “Energy Savings” appears on the left side of the display. Energy
Savings mode engages the settings configured in
SECTION 8
Energy Saving Mode
.
2.
When the unit is on, the display will show the current conditions (temperature and
humidity level) as well as if it is in Energy Savings mode or not. Other icons/information
that may be on the display include:
Fan icon appears when the fan is on.
“HI°
F
” appears if the intake temperature is above 150°F.
“Lo°
F
” appears if the intake temperature is below 15°F.
“Lo%” appears if the intake humidity is below 10%.
3.
Optional Heater Unit:
An optional heater unit is available for climates that the air coming
into the unit falls below 54°F. To install the unit, follow the direction that are included
with that unit. The display will show a thermometer icon with either a “1” or “1 2” when
the temperature range is at a level where the heating element would come on if present.
Stage 1 - “1” turns on when the intake air temperature is between 39°F and 54°F. Stage
1 and 2 “1 2” turn on when the intake air temperature is between 33°F and 39°F.
4.
To restore the factory setting, make sure the unit is in the “OFF” setting. Hold both the
“UP” and “DOWN” buttons for approximately 5 seconds. The “OFF” on the display will
flash to confirm the settings have been restored.
