- On the thermostat’s display you see an X (X with No Dots) in the upper right hand corner.
- You will also receive a notification on your Pelican web-app stating: “Thermostat Name (Serial No: XXX-XXXX) Check Wiring Module.
From the app, you can navigate to the thermostat’s configuration page, scroll to the bottom and select Signal Outputs: if you see an X next to Relay Wiring Module under Communication Status then the thermostat is unable to communicate with its relay module. This will turn to a check mark when communication is restored.
