The thermostat will not connect to the mobile app or cannot be discovered during setup, even though Wi-Fi is working.

Safety: No electrical work is required.

• Step 1 – Same network check: Ensure that your phone is connected to the same 2.4 GHz Wi-Fi network as the GLAS during setup.
• Step 2 – Router settings: Enable multicast, UPnP, and mDNS/Bonjour on your router. Disable client isolation or AP isolation.
• Step 3 – Update software: Update the GLAS app on your phone and ensure that the GLAS firmware is current.
• Step 4 – Reboot devices: Reboot your phone, the router, and the GLAS thermostat.
• Step 5 – Factory reset (last resort): If pairing still fails, factory reset the GLAS and attempt the setup again from the app.
