The Additional Smart Radiator Valve adjusts the temperature in each room of your home

Additional Smart Radiator Valve

This product is not available in your country.

Decide the temperature of each room based on your needs

The Additional Radiator Valve enhances your Thermostat, Modulating Thermostat or Starter Pack set-up to help you control your heating in every room.

Set the temperature in every room at any time, even when you’re not home

Your Additional Radiator Valves are smart, so you can control them remotely through the Energy or Home + Control app. When you’re at home, you can also control them manually or with your voice.

Don’t waste any more energy

Enjoy a comfortable and energy-efficient home using the smart features, which can be easily set up through the app. For example, the Open Window Detection feature turns off the radiators automatically when the windows are open.

Comfort or savings? What’s your priority?

You can choose between two heating modes. The Comfort priority allows the Radiator Valve to heat certain rooms to a higher temperature than that set by the Thermostat. Meanwhile, the Eco priority asks it to limit the temperature.

Equip all your radiators

Your smart heating can control up to 20 Radiator Valves. Set the temperature of each room to suit how you use it and the time of day to optimise your energy use.

FAQ

I have several radiators in one room. Do I have to fit them all with Smart Radiator Valves?

A Smart Radiator Valve allows you to regulate the temperature of a room by controlling the flow of hot water to the radiator where it is installed. If you have several radiators in the same room, we recommend that you equip all the radiators in that room so that they can synchronise to ensure an even temperature in the room.

Can I leave manual valves in my system?

If your installation also has manual valves, you can leave them as they are or replace them with Smart Radiator Valves after replacing the valve body with a compatible thermostatic model.

Can I use a different brand of thermostat with the Netatmo Additional Smart Radiator Valves?

No, because another brand's thermostat will interfere with the Smart Radiator Valves’ schedule.

How many Additional Smart Radiator Valves can I add to the thermostat or the collective heating pack?

If you already have a Thermostat, check the settings in the Netatmo Energy app to see how many additional Smart Radiator Valves you can add. If you get a new Netatmo Thermostat, you can add up to 20 Smart Radiator Valves in up to 10 different rooms.

Can I temporarily increase the temperature in a room when the Thermostat has already reached its setpoint temperature?

Yes, you can use the Manual Boost feature from the app or on the Smart Radiator Valve to temporarily increase the temperature in a room. The Manual Boost feature will turn on the boiler and take control of the Smart Thermostat’s schedule.

In my schedule, can I select a higher temperature for a particular room even though the thermostat is in a different room?

Yes, but the room will only heat up according to the selected operating mode: • In ECO Priority mode, the Additional Smart Radiator Valves will only heat up when the room with the Thermostat also needs to be heated and they will not exceed the setpoint temperature. • In COMFORT Priority mode, the Additional Smart Radiator Valves can activate the heating via the Thermostat so that they can warm up their room even if the room with the Thermostat does not need to be heated.
