Thermostat shows incorrect time or time zone, causing schedules to run at the wrong times.

Safety: No mains work required.

Steps:

• Check app settings: Open the Meross app, select the thermostat, and verify the time zone and region settings. Correct them if necessary.
• Ensure online status: Confirm the thermostat is online (no offline indicator). Fix Wi‑Fi issues if needed so it can sync time.
• Disable/enable schedules: Toggle schedules off and back on after correcting time to force a refresh.

Outcome: If time still drifts significantly while online, the RTC hardware may be faulty (see E13 scenario) and the thermostat may need replacement.
