Starter Pack - Smart Radiator Valves Installation Guide

Easy to install yourself

It’s easy to replace your existing thermostatic valves, even when the radiator is on. No technical expertise is required. NB: water cannot flow from the radiator during installation.

10 minutes

Several installation options

  • You’re replacing thermostatic valves

    Replace your current thermostatic valves in two steps. Thermostatic valves have a numbered scale (usually from 1 to 5).
    1. Unscrew the existing thermostatic valve.
    2. Screw on the new Netatmo Smart Radiator Valve.
  • You’re replacing manual valves

    Manual valves for radiators can only switch the heating on or off and do not have a numbered scale (the standard scale generally goes from 1 to 5).
    You should call a professional if you want to replace a manual valve.

My Smart Radiator Valve doesn’t respond when I put in the batteries, what should I do?

You can find all the information you need here.

Do the Smart Radiator Valves still work if the Wi-Fi connection is lost?

If the Wi-Fi connection is lost, the Smart Radiator Valves continue to follow the schedule or the temporary setpoint temperature requested. The heating can also be controlled manually from the Smart Radiator Valves.

What is a free-flow radiator? Should I install a smart radiator valve on this type of radiator?

A free-flow radiator is a radiator that must always be left open to allow hot water to flow through it. This type of radiator is typically found in a living room or hallway. Controls should not be added to this kind of radiator as it could damage the heating system. Therefore, a Smart Radiator Valve should not be installed.

Who can control the Smart Radiator Valves?

Anyone who has a Netatmo account linked to the products. It's possible to share access among multiple users.
