Possible Causes
How to Fix / Troubleshooting
Safety: Ensure the heating system is not under excessive pressure when working on valves; do not loosen the radiator body itself.
- Identify valve type: Check the radiator valve body for markings (e.g., M30x1.5, Danfoss RA/RAV/RAVL) and select the correct Netatmo adapter.
- Inspect adapter: Look for cracks or stripped threads on the adapter; replace if damaged.
- Install straight: Screw the adapter and then the Smart Radiator Valve on straight and hand‑tighten firmly without cross‑threading.
- Use manufacturer‑approved adapter: If your valve is non‑standard, obtain a compatible adapter from Netatmo or a plumbing supplier.
If a secure fit cannot be achieved with the correct adapter, the radiator valve body may need to be replaced by a plumber.
