Intelligent radiator valve - Radio link with NVS-THERMOSTAT - Temperature control per room - Universal valve adapters - Compatible with TUYA Smart - Compatible with Alexa and Google assistant

Válvula termostática inteligente Nivian Smart,para radiador de agua en circuito de caldera.
Controls the temperature of individual rooms, working in conjunction with the NVS-THERMOSTAT.

Simple installation, without draining the water or intervening 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 due to different adapter threads. Para identificar el tipo de válvula exixtente, se debe observar el aspecto de la válvula, ya que las válvulas termostaticas se diferencian de las manuales porque presentan algún tipo de escala de valores o pasos en sus posiciones de giro y de una rosca de fijación para poder separarse del cuerpo de la válvula, mientras que las manuales son simples manetas que indican apertura o cierre con sentidos de giro y no incorporan ninguna rosca de fijación.

La válvula inteligente o eTRV, se comunica vía radio con la central de comunicación HUB del NVS-THERMOSTAT, para poder operar desde la app, por lo que es necesario disponer de este producto previamente.
The most outstanding features of this solution are:

Long range via radio (80 m open space) to be installed on any radiator in the room.
