Thermostat does not follow programmed schedule; heating turns on and off at unexpected times.

Safety: No electrical work required.

• Check date and time: Ensure the thermostat clock and day of week are correct. Enable automatic time sync if available.
• Review schedules: Go through each time period for each day and confirm setpoints and times are as desired, with no overlaps.
• Clear overrides: Cancel any manual holds or party modes that may be overriding the schedule.
• Disable special modes: Turn off holiday, frost protection, or eco modes if they are not intended.
• Update firmware: Install any available firmware updates that address scheduling issues.
