CAUTIONS
Use cautions when mounting components to surfaces that
may have concealed wiring beneath the surface.
Turn off power before installing whole house fan or controls.
Read and follow all instructions carefully, including those
included with the whole house fan. Read entire manual
before installing products.
Follow all local electrical codes during installation. All wiring
must conform to local and national electrical codes.
Installation should be performed by a qualified individual
with sufficient experience and skill.
!
The WTTK kit includes a WTT Whole House Fan Wall
Control, an FC3J Fan Control and a 50’ plug&play cable.
The optional TS3J Outdoor Temperature Sensor can be
added to the installation to delay fan operation if the
outdoor temperature is too warm to provide cooling.
When servicing WHF controls, turn off all power to these
items.

Use the screws included to secure the
FC3J to the junction box on the fan
making sure there are no exposed
wires and the fan control is securely
inside the electrical box. Failure to do
so could result in electrical shock.
The WTT is installed in a plastic retrofit
single gang box in the sleeping space on a
wall about 5’ off the floor in a location that
will best sense the temperature for the
space. Do not install in a location where
the temperature will be influenced such as
in direct sunlight, on an exterior wall, etc.
Do not install WTT in a metal gang box.
Step 2. Connect Cable to the FC3J
Connect one end of the “RED” Plug&Play cable into the FC3J
fan control already installed on the junction box on the fan.
Feed this end
to the gang box
Insert into FC3J
already installed
on fan.
See FC3J Wiring Diagrams on pages 3-4 for wiring to
fans manufactured by QC Manufacturing.

Step 4. Feed Cable to Gang Box
If the optonal TS3J Outdoor Temperature Sensor is
being installed, install it now. (See the TS3J Installer
Guide.)
Feed the other ends of the cable from
the FC3J and the TS3J (if installed)
through the wall and the opening in the
gang box. Insert the gang box into the
wall opening and secure.
i
If a sensor is installed, connect the cable with the “YELLOW”
marker into the “YELLOW” connector.
Step 6. Power the Fan
Apply power to the fan. If the fan automatically starts up,
remove power and check the wiring. If the problem persists,
contact us.
Verify that the WTT Wall Control LCD is displaying, indicating
the the WTT is receiving power.
Step 8. Set the Number of Fan Speeds
The WTT is factory set to a two speed fan. For three-speed or
one-speed fan installations, the number of fan speeds available
needs to be changed to reflect the type of fan installed.
To change the number of speeds, PRESS and HOLD
until the first option is displayed. PRESS again to
display the number of speeds. PRESS to set a 3-speed
fan or PRESS to set a 1-speed fan.

Warranty
This thermostat is warranted to be free of defects due to workmanship
or materials under normal use and service for a period of 5 years from
date of installation and not longer than 6 years from manufacturing
date code.
eControlseControls
Ensure that the cable is completely plugged into the “RED”
connector on the WTT and the FC3J. You should hear the
connectors click. Ensure that the fan is powered. Ensure the
wiring from the FC3J fan control to the whole house fan is
correct.
Ensure that the number of speeds set in Step 7 correspond to
the type of fan installed - 1-speed, 2-speed or 3-speed fan.
The WTT LCD is not lit.
Fan speeds available is not correct.
TROUBLESHOOTING
If On is not blinking and the WTT is in Temperature Control,
make sure the Set To temperature is a few degrees lower than
the Indoor temperature. On will blink when the fan is running.
If an outdoor temperature sensor is installed and the outdoor
temperature is above the limit set, whole house fan operation
may be delayed. When delayed, “LIMIT” blinks.
If On is blinking but the fan is not running, check the wiring
from the FC3J fan control to the whole house fan.
The display indicates On but the fan is not running.
