Continuous Ventilation:
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. Run 2 wires from
a properly grounded wall switch (not included) to the fan. Connect the Black wire of the
fan to the Black wire (Hot) from the power source. 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).

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. A manual override switch (not
included) can be used to provide a manual fan Off function.
(Figure 9).

Carefully tuck wire back inside wire compartment and replace wire compartment cover
securing with the screw that was removed earlier.
NOTE:
The fan’s receptacle wires might need to be pulled outside compartment for connection.
Only pull the five loose wires outside of compartment. Additional wires will be present.
NOTE:
Unit must be grounded according to all local and national codes.

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 the
Black wire from the supply to the input side. Connect the Yellow wire from the fan to the
other side. Closing the switch will change from normal to high speed. A manual override
switch (not included) can be used to provide a manual fan Off function.

SECTION 6
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.
NOTE:
This fan is rated for direct insulation contact (Type IC) and it is recommended that this fan
be completely covered by insulation in order to reduce heat loss or gain to unconditioned space.
2.
If the fan’s blower assembly was removed during the wiring process, reinstall the
blower by reversing the directions in
