SECTION 6
Wiring
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
CAUTION:
ALL ELECTRICAL CONNECTIONS MUST BE
MADE IN ACCORDANCE WITH LOCAL CODES, ORDINANCES, OR
NATIONAL ELECTRICAL CODE. IF YOU ARE UNFAMILIAR WITH METHODS OF INSTALLING
ELECTRICAL WIRING, SECURE THE SERVICES OF A QUALIFIED ELECTRICIAN.
NOTE:
This unit includes a side access panel for wiring that does not require the removal of the
fan’s blower assembly.
1.
Remove the wire compartment cover screw and place cover in a secure place
(Figure 6).
2.
Pull the loose black, white and green wires out from the wire compartment (additional
wires will be present). Install an approved electrical connector (not included) to the wire
compartment cover. 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 7)
. Use approved
methods for all connections.
3.
Carefully tuck wire back inside wire compartment and replace wire compartment cover
securing with the screw that was removed earlier.
SECTION 9
Activating the Boost Speed
If your unit is equipped with a boost speed, and it is determined that additional flow is necessary
due to excessive duct resistance or other field conditions activate the boost speed by:
1.
Find the 2 wire harness from the fan motor to the capacitor.
2.
Disconnect the harness from the capacitor at the quick connect fitting and remove the
“Boost Label” from the quick connect fitting on the boost capacitor.
3.
Plug the motor harness into the boost capacitor.
SECTION 4
Wire Harness
4.
Unplug the 3-pin quick connect motor plug from the wire compartment and plug it into
the 3-pin receptacle on the controller harness coming from the filter box. Connect the
3-pin quick connector plug from the harness into the wire compartment receptacle
(Figure 3)

Setting the Controller
Your unit may be equipped with an integrated digital controller. To access the controller, open the
filter access lid as described in
SECTION 2
. 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

.
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 5
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.
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.
