Thermostat shows E11 and mobile app cannot connect or control the thermostat remotely.

Safety first: No electrical work is required for this issue.

Steps to troubleshoot:

• 1. Verify local control: Confirm the thermostat can be controlled directly at the wall and that Wi‑Fi is connected without errors.
• 2. Check Bryant app status: Log out and back into the Bryant app. Check for app updates in your device’s app store.
• 3. Update thermostat firmware: In the thermostat settings, check for firmware updates and apply any available updates, following on-screen instructions.
• 4. Relink account: Remove the thermostat from your Bryant app account, then re-add it using the pairing or registration process provided in the app.
• 5. Check for outages: Visit Bryant support resources or status pages to see if there is a known cloud service outage.
• 6. Network checks: Ensure your router is not blocking outbound HTTPS traffic or using DNS filtering that could interfere with cloud connections.
