Additional Smart Radiator Valve FAQ

The Valve system

How do the Valves work?

Our Smart Valves use two integrated temperature sensors to measure the temperature in the room. They compare the actual temperature in the room to the setpoint temperature, regulating the hot water flow in the radiator to control the temperature.

How do the Valves communicate?

Our Smart Valves only connect with the Relay. They connect via long-range radio frequency. The Relay then uses Wi-Fi to communicate with the router. We recommend that you position the Relay somewhere central in your home.

Organising my home - I have an individual boiler

How many Additional Valves can I connect to one Thermostat?

If you already have a Thermostat, you just need to check the parameters in the Netatmo Energy App to see how many Smart Valves you can connect (from 5 to 20 Smart Valves). If you are buying a new Netatmo Thermostat, you can connect up to 20 Smart Valves.

Do I need to place Smart Valves in all of the rooms in my home?

We recommend that you install one on each radiator, including in the same room as the Thermostat to ensure the greatest possible comfort in all of the rooms in your home. For example, the bathroom temperature could be 21 °C and the room containing the Thermostat could be at 19 °C thanks to the Smart Valves.

Do I need to install a Valve in the same room as the Thermostat?

If there is no Valve in the same room as the Thermostat, your Thermostat will stand in and regulate the temperature in that room.

When I set the temperature schedule, can I make any rooms warmer than the one where the Thermostat is?

Yes, it is possible in comfort mode. For this to work, you will need to install Smart Valves in the same room as your Netatmo Smart Thermostat. This could be in your living room, for example. The Smart Valves in your living room would then regulate the flow of hot water, distributing more to other rooms, where higher temperatures have been set.

What happens to rooms without Smart Radiator Valves?

In homes with individual heating systems and a Netatmo Smart Thermostat, rooms without Smart Radiator Valves are heated to the Thermostat setpoint temperature when the boiler is on.

Installation

I have several radiators in the same room. Do I need to install a Smart Valve on each one?

A Smart Valve regulates the temperature in the room by controlling the flow of water in the radiator on which it is installed. So if you have several radiators in the same room, we recommend that you equip each one with a Smart Valve so that they can synchronise with one another and ensure a consistent temperature throughout the room.

Can I leave manual valves in my system?

If your system features manual valves you can leave these in place or replace them with thermostatic valves.

Can I use another brand of thermostat with Netatmo Smart Radiator Valves?

No. A thermostat made by another company would interfere with the Smart Valves' scheduling.

Organising my home - I have district heating

How many Additional Valves can I connect to one pack for district heating?

If you have a pack for district heating, you can install up to 20 valves.

Do I need to place Smart Valves in all of the rooms in my home?

We recommend that you install a valve on each radiator in your home in order to save as much energy as possible and make your home as comfortable as possible.

What happens to rooms without Smart Radiator Valves?

In homes connected to collective or district heating systems, rooms without Smart Radiator Valves are heated when the hot water reaches the radiators.
