TC Thermostat Symbols
TC1, TC2, TC3, and TC4 thermostats display symbols in the upper-right corner to indicate status updates and troubleshooting information. Below is a guide to understanding these symbols:
| Symbol | Meaning & Recommended Action |
|---|---|
(No Internet)
|
Connected to the Pelican Wireless Mesh Network but cannot reach the internet.
✅ Check your Pelican Gateway status for power and network connectivity. ✅ Ensure there are no gaps in your Pelican wireless network between the thermostat’s wireless connection point and the main wireless network with the Pelican Gateway. |
(No Wireless)
|
Cannot find the Pelican Wireless Mesh Network.
✅ Verify that the thermostat is within range of other Pelican devices or a repeater. ✅ Check if any repeaters or access points are Offline. |
(Notice)

Because this symbol can represent multiple statuses, touching the symbol on the thermostat will bring you to the Info page for detailed text information. Below are the possible meanings and recommended actions:
1. Unable to communicate with wiring module (WM500 or WM700). ✅ Ensure the thermostat is properly wired to the wiring module. ✅ Check that the [R] and [C] wires are correctly connected between the thermostat and wiring module. If reversed, devices may power on but will be unable to communicate. ✅ Ensure there are no splices or loose connections between the [D] terminals. ✅ Confirm that all wires are properly seated in terminals and that all terminals are securely tightened. ✅ Test communication by re-mounting the wiring module back into the thermostat's backplate. 2. CO₂ levels have exceeded the configured warning threshold. ✅ Review the CO₂ warning configuration and adjust if necessary. ⚠️ This notification is not designed an indication of a dangerous or emergency situation. High CO₂ warnings indicate a higher than normally space occupancy. For assistance or more information contact Pelican Technical Support. 3. Participation in Community Energy Event. ✅ The thermostat is currently in an energy efficiency state due to a community utility demand shed load event. ✅ If needed, the thermostat will provide an option to override and opt-out of the event. 4. Thermostat is in vacation mode. ✅ Review the vacation schedule and adjust if necessary. |
(Locked)
|
Restricted Thermostat Options
