Smart thermostat cannot be discovered or added in the Eurotronic app during setup.

Safety: No mains work is required for pairing.

• Update app: Install the latest version of the Eurotronic app on your smartphone.
• Reset device: Perform a factory reset on the thermostat to clear previous pairings.
• Correct pairing mode: Follow the manual to enter pairing mode (often indicated by a flashing RF or Wi‑Fi symbol). Start the add-device process in the app within the specified time.
• Check Wi‑Fi band: Ensure your phone is connected to a 2.4 GHz network if the thermostat does not support 5 GHz.
• Move closer: Stand near the thermostat and router during pairing to reduce interference.
• Replace thermostat/gateway: If multiple attempts fail and other devices pair normally, the thermostat’s RF/Wi‑Fi module may be defective and require replacement.
