Troubleshooting

Lost Signal
If the no-Wi-Fi indicator displays in place of the
Wi-Fi strength indicator in the upper right hand
corner of the home screen:
• Check another device to be sure Wi-Fi
is working in your home; if not, call your
Internet Service Provider.
• Move the router.
• Restart the thermostat: remove it from
the wallplate, wait 10 seconds, and snap it
back onto the wallplate. Return to Step 1 of
Connecting to your Wi-Fi network.
Error Codes
For certain problems, the thermostat screen will display
a code that identifies the trouble. Initially, error codes
are displayed alone in the time area of the screen; after a
few minutes, the home screen is displayed and the code
alternates with the time.
