Problem Description
If the T10 is ignoring schedule changes, the thermostat time zone or schedule settings may be off. This guide checks schedule status and restores timing accuracy.
Why This Happens in Real Homes
If the T10 is ignoring schedule changes, the thermostat time zone or schedule settings may be off. This guide checks schedule status and restores timing accuracy. In day-to-day use, this usually looks like Schedule does not run; Manual changes work; Temperature holds too long.
Most cases trace back to Time zone incorrect; Schedule paused; Hold mode active. The fix works best when you go step by step instead of changing multiple settings at once.
A practical order for this issue is: Check Time Zone -> Resume Schedule -> Disable Hold -> Reconnect WiFi. After each step, test the exact behavior that was failing so you can confirm what actually solved it.
