3. Feed any loose communication wiring inside the
cavity of the universal mount or back down the
downtube to ensure it does not prevent the mount
cover from being installed.
4. Identify the desired location for installation of the
fan control and run the remainder of the shielded
CAT-5e control cable to this location.
5. Secure the shielded CAT-5e control cable to the
building structure to ensure it does not interfere
with fan performance. To prevent communication
issues, do not coil excess control cable or route
control cable with power wiring.
6. If one control source will be used to operate
multiple fans, the fans can be daisy-chained
together to create a network using the following
instructions.
a. Connect a shielded CAT-5e control cable to
the first fan in the daisy-chain using steps 1-3
above.
b. Plug an additional CAT-5e control cable into the
2-way RJ45 splitter located at the top of the
downtube on the first fan. Connect the other
end of this CAT-5e cable into the 2-way splitter
on the next fan.
