CAUTIONS
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.
Use cautions when mounting components to surfaces that
may have concealed wiring beneath the surface.
When servicing WHF controls, turn off all power to these
items.
Step 1. Install FC3J in Junction Box on Fan
Wire the FC3J to the fan using the diagram below as a guide. If
the FC3J fan control is already installed on the fan, go to Step 2.
See FC3J Wiring Diagrams on pages 3-4 for wiring to
fans manufactured by QC Manufacturing.

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
Step 3. Install a Plastic Retrofit Gang Box
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.
