the White wire of the fan to the White (Neutral) wire from the power source. Connect the
ground wire from the house to the green wire from the fan housing. Connect the Black
wire of the fan to the Black wire (Hot) from the power source. Using a properly grounded
standard duplex toggle switch (such as Leviton 5224-2W, not included) connect the Black
wire from the supply to one side of the top and bottom switch. Connect the Red wire (light)
from the fan housing to the other side of the top switch and connect the Purple wire (night
light) from the fan housing to the other side of the bottom switch. Using a second properly
grounded standard duplex toggle switch, connect the Hot Yellow wire from the fan to the
input of the switch. Connect the second Yellow wire from the fan to the output side of the
switch. Closing the switch will change from normal to high speed (Figure 8).

3. For two speed fans wired for continuous ventilation, connect the White wire of the fan to
the White (Neutral) wire from the power source. Connect the ground wire from the house
to the green wire from the fan housing. Connect the Black wire of the fan to the Black
wire (Hot) from the power source. The fan will operate on low speed continuously and
boost to high speed when motion is detected. Using a properly grounded standard duplex
toggle switch (such as Leviton 5224-2W, not included) connect the black wire from the
supply to one side of the top and bottom switch. Connect the red wire (light) from the fan
housing to the other side of the top switch and connect the purple wire (night light) from
the fan housing to the other side of the bottom switch. A manual override switch (not
included) can be used to provide a manual fan Off function (Figure 9).

4. For two speed fans wired for continuous ventilation, connect the White wire of the fan
to the White (Neutral) wire from the power source. Connect the ground wire from the
house to the Green wire from the fan housing. Connect the Black wire of the fan to the
Black wire (Hot) from the power source. The fan will operate on low speed continuously
and boost to high upon a rise in humidity. Using a properly grounded switch, connect 1
yellow wire to each side of the switch. Closing the switch will change from normal to
high speed. Using a properly grounded standard duplex toggle switch (such as Leviton
5224-2W, not included) connect the Black wire from the supply to one side of the top
and bottom switch. Connect the Red wire (light) from the fan housing to the other side
of the top switch and connect the Purple wire (night light) from the fan housing to the
other side of the bottom switch. A manual override switch (not included) can be used to
provide a manual fan Off function (Figure 10).

Completing the Installation
1. 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 is recommended. If gaps between unit housing and ceiling are great, additional
material (backing rod, ceiling material) may be required.
