The thermostat fails to detect open windows, or eco features do not activate.

Safety: Only configuration changes are required.

Steps:

• Check the thermostat settings for open‑window detection or eco features and ensure they are enabled.
• Increase the sensitivity or detection threshold if adjustable.
• Ensure the thermostat is located where it can sense rapid temperature drops (not behind curtains or furniture).
• Update the firmware to the latest version to ensure all features are available.

Remedy:

• If features remain unavailable, consult Glow‑worm documentation to confirm whether your specific model and region support them.
