Ngenic thermostat fails to detect or control one specific zone or room equipped with Ngenic smart radiator valves.

Safety: Radiators may be hot; use caution.

• Check device list: In the Ngenic app, verify that the radiator valve in the affected room is online and assigned to the correct room/zone.
• Replace batteries: Install fresh batteries in the valve actuator.
• Re-pair valve: Remove the valve from the app and add it again, then assign it to the correct room.
• Improve RF path: Move metal objects away from the valve and, if possible, reposition the Ngenic control module or add a repeater if supported.

If the same valve repeatedly drops offline while others are stable, replace that Ngenic smart radiator valve actuator.
