Heating does not start at scheduled times; schedule appears to be ignored.

Safety first: No electrical work is required.

• Verify date and time: Check that the thermostat’s clock and day of week are correct.
• Review schedules: In the app or thermostat, review each time program to ensure it is active on the intended days and times.
• Check special modes: Disable any holiday, eco, or party modes that may override normal schedules.
• Test manual override: Set a manual higher setpoint to confirm that the system can heat when commanded.
