Thermostat does not follow programmed schedule; heating/cooling occurs at wrong times.

Safety: No electrical work is required.

Steps:

• Verify the current time, date, and day of week on the thermostat; correct them if necessary.
• Check time zone settings in the thermostat or associated Schneider Electric app.
• Ensure that the schedule function is enabled and that no permanent manual hold is active.
• Review each schedule period to confirm correct start times and setpoints.
• If the thermostat loses time after power interruptions, the internal RTC or backup battery may be failing; replace the thermostat or backup battery if user-serviceable.
