Thermostat does not follow the programmed schedule; temperature setpoints change at the wrong times or not at all.

Safety: Software issue only; no electrical work required.

• Step 1 – Verify time and date: In GLAS settings, confirm the time, date, and time zone are correct. Enable automatic time sync if available.
• Step 2 – Review schedule: Check each schedule period (wake, away, sleep, etc.) for correct times and setpoints. Correct any overlapping or duplicate entries.
• Step 3 – Disable conflicting modes: Turn off any smart home integrations or occupancy‑based overrides temporarily to see if they are changing setpoints.
• Step 4 – Reboot and update: Power cycle GLAS and install any firmware updates.
• Step 5 – Reset schedule: Delete the existing schedule and recreate it from scratch. If issues persist, perform a factory reset and reconfigure.
