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

Safety: This is a software issue only; no electrical work is required.

• Step 1 – Verify time and date: In the GLAS settings, confirm that 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 the correct times and setpoints. Correct any overlapping or duplicate entries.
• Step 3 – Disable conflicting modes: Temporarily turn off any smart home integrations or occupancy-based overrides to see if they are changing the setpoints.
• Step 4 – Reboot and update: Power cycle the 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.
