Thermostat frequently drops connection to the app or gateway, then reconnects later.

Safety: Network changes do not require opening mains equipment.

• Check signal strength: In the app or router interface, verify that the thermostat has adequate signal (at least 2–3 bars).
• Relocate router/gateway: Move the router or Eurotronic gateway closer to the thermostat or to a more central location.
• Change Wi‑Fi channel: Set the router to a less congested channel to reduce interference from neighboring networks.
• Limit router load: Disconnect unused devices or upgrade the router if it is overloaded.
• Replace module/gateway: If only this thermostat has issues while others are stable, its Wi‑Fi module may be failing and should be replaced.
