Further Enhancing Reliability

As signals travel via the power line or RF throughout the home, they naturally become weaker the farther
they travel. The best way to overcome weakened signals is to increase the coverage of the mesh network
by introducing more INSTEON devices.
It is possible that some audio-video devices, computers, power strips, or other electrical equipment may
attenuate INSTEON signals on the power line. You can temporarily unplug suspected devices to test
whether the INSTEON signal improves. If it does, then you can plug in filters that will permanently fix the
problem.

TROUBLESHOOTING

Problem
The Status LED on
SwitchLinc is not
turning on and won't
control the load.
SwitchLinc won't Link
or work with a
Controller or
Responder.
SwitchLinc is taking a
long time to respond to
a Controller.

Possible Cause
SwitchLinc may not be
getting power.
The Controller or
Responder might have
been reset without
Unlinking SwitchLinc from it.
The Controller or
Responder and SwitchLinc
may be on opposite power
line phases.
The INSTEON signal may
be too weak.
Large appliances, such as
refrigerators or air
conditioners, may be
producing electrical noise
on the power line.
Other electrical devices,
such as computers,
televisions, or power strips,
may be absorbing the
INSTEON signal.
The Controller may be
sending commands to a
Responder that is no longer
in use. Commands for the
unused Responder are
being resent and loading
down the signal.

Solution
Make sure the circuit breaker is turned on.
Make sure the air gap (Set button) is not pulled out.
Check the junction box wires to ensure all
connections are tight and no bare wires are exposed.
Check the light fixture to ensure all connections are
tight and no bare wires are exposed.
Re-Link SwitchLinc to the Controller or Responder.
Make sure two dual-band INSTEON devices are
properly installed to bridge the two power line
phases.
Add additional INSTEON devices or move around
existing INSTEON devices. All INSTEON devices act
as INSTEON network repeaters.
Install a power line noise filter (#1626-10) to filter
electrical noise and minimize signal attenuation.
Unlink any unused Responders from the Controller.
HINT: If you are using home automation software,
you can easily check scene membership and
eliminate unnecessary Links.
If the above doesn't work, perform a factory reset on
the Controller.
