Smart thermostatic valve Nivian Smart, for water radiator in boiler circuit.
It controls the temperature of the rooms individually, in cooperation with the NVS-THERMOSTAAT thermostat.

Easy installation, without the need to drain the water or intervene in the radiator circuit, simply by replacing the thermostatic valve attached to the metal body of the radiator valve.
Universal compatibility with most existing thermostatic (non-manual) radiator valves, thanks to the various adapter threads. To identify the type of existing valve, the appearance of the valve must be considered, since thermostatic valves differ from manual valves in that they exhibit some kind of scale of values or steps in their rotational positions and a fixing thread to separate from the valve body , while manual handles are simple handles that indicate opening or closing with directions of rotation and do not include a fixing thread.

The intelligent valve or eTRV communicates by radio with the communication center HUB of theNVS-THERMOSTAAT, to work from the app, so it is necessary to have this product in advance.
The most notable features of this solution are:

  • Large range by radio (80 m open space) install on any radiator in the room.
  • Stable communication.
  • Runs on batteries, without the need for electrical outlets.
  • Low consumption, average autonomy 1.5 years.

The features we can find in the smart valve are:

  • LCD display with temperature, date / time, battery, programming and mode indicator.
