Troubleshooting
Problem Possible Cause Solution
Thermostat does not
respond to Off commands.
Did not “link to off”
See Adding Thermostat as an INSTEON
Responder and link to “Scene Off.”
LED won’t come On. Difficulty viewing LED
Turn off room lights.
Hold a piece of white paper at a 45-degree angle up
against wall just below the thermostat. This will act
as a reflector making the LED must easier to see.
Thermostat won’t add to
scene as a responder.
The controller may have dropped out of
linking mode or linked to another
device.
Try relinking thermostat to the controller.
The INSTEON signal may not be
getting to the “vicinity” of thermostat.
Make sure phases are bridged, Add additional
INSTEON devices and/or move around existing
INSTEON devices.
Large appliances, such as refrigerators
or air conditioners, may be producing
electrical noise on the powerline.
Install a powerline noise filter (FilterLinc #1626-10)
to filter electrical noise and minimize signal
attenuation.
Other electrical devices, such as
computers, televisions or power strips,
may be absorbing the INSTEON signal.
