Thermostat does not follow programmed schedule; heating comes on at wrong times.

Safety note: No electrical work is required.

Steps to correct scheduling:

• 1. Verify time and date: Ensure the thermostat clock and day of week are correct. Adjust if necessary.
• 2. Review all schedules: Go through each time period for each day or zone and correct any overlapping or unintended setpoints.
• 3. Clear overrides: Cancel any manual overrides or boost functions that may be holding a different temperature.
• 4. Check special modes: Ensure holiday, party, or frost protection modes are not active.
• 5. Factory reset if corrupted: If behaviour remains erratic, perform a factory reset and re-enter the schedule from scratch.

When to call a professional: If the thermostat still ignores schedules after reset, the firmware or memory may be faulty and the unit should be replaced.
