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 WTTKWF kit includes a WTT Whole House Fan
wall control, an FC3J Fan Control, a WFM Plug-in WiFi
Module 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, Inc.
