Troubleshooting - Lennox iComfort S30 Smart Thermostat Operating, Troubleshooting And Technical Cheat Sheet

1. Wireless Connection between Mobile Device and Smart Hub
Issue: Your mobile device (smart phone or tablet) will not connect to the Smart Hub using the procedures in the installation
and setup guide. Then try the following possible solution.
Solution: Disable mobile data on your device if applicable.
S
Android 4.4 - Go to Settings > Wireless & Networks > More > Mobile Networks > Data Enabled and un-check
this option
S
Android 5.x - Go to Settings > Connections > More Networks > Mobile Networks > Mobile Data and unchecked
this option.

S
Note: When mobile (cellular) data is successfully disable, Icons for 2G, 3G or 4G will not longer be present on
the main screen.
Try to connect to Smart Hub. Reports indicate that disabling mobile data will reduce the interference that may be causing
the connection issue.
REMINDER: Do not forget to turn your mobile data setting back on when you are finished with the Lennox Mobile Setup
application.
2. Mag-Mount (Front Cover) and HD Display
Issue: When mag-mount is powered and the HD Display is not attached there is a bright blue LED that can be seen on the
front. If it is solid blue then you have voltage. It also indicates the mag-mount is communicating with the smart hub. If the
blue LED is blinking that means that the mag-mount has proper voltage but is not communicating. This may indicate a
wiring issue.
Solution: Verify that when you reinstall the mag-mount front terminal cover to make sure it sets flush with the base. There
has been three systems replaced due to the cover not being reinstalled properly. This issue was caused by extra wiring left
in the terminal area kept the cover from going down all the way. If this happens the HD Display will not be powered. What
happens is the display will try to start but then go blank or bring up a pop up saying it can not connect. A quick look at the top
of the mag-mount looking down through the vent holes on the mag-mount you would see the blue light on. When the HD
Display is making contact their will be no blue light on.
