Yellow exclamation mark appears on one of the zones

Open

The yellow triangle (exclamation mark) indicates a temporary communication issue between the temperature sensor and the central processing unit (CPU) installed in the roof.

Troubleshooting Steps:

1. Check if the Actual Temperature is Displayed:

   • If the actual temperature is still visible, the issue may be a minor glitch.

   • If the actual temperature is missing, it indicates a loss of communication.

2. Reset the Controller:

   • Press the blue reset button once (located under the control panel).

   • Wait for the screen to reboot and return to the main menu.

3. Verify Zone Status:

   • Check that all zones display an actual temperature value.

   • Ensure the wireless signal range and battery icon are visible in the top-right corner of the zone page.

Next Steps:

• If the issue persists after resetting, check for any obstructions or interference affecting wireless communication.

• If the problem continues, contact support for further assistance.
