Thermostat shows incorrect day/time or schedule runs at wrong times

Safety: Only configuration changes are needed.

Steps:

• Open the thermostat settings and verify the time, date, and time zone. Correct them if necessary.
• Enable automatic daylight saving time adjustment if available.
• If the thermostat is internet‑connected, enable automatic time synchronisation.
• Review each schedule period to ensure the correct start and end times and days are selected.

Remedy:

• If the clock continues to drift significantly, the internal RTC may be faulty; replacement of the thermostat may be required.
