Terma electric convector heater provides instantaneous heat, with fully integrated wifi functionality - allows full remote control via the Terma SMART app. Terma VOLTAN is modern, easy to use, efficient, and at the same time very flat, almost indistinguishable against the background of the wall. The controller is flush with the front of the panel for a very sleek and simple design. Allows full temperature control ambient room temp (15°c to 26°c) regulation. The device can be controlled by means of the free TERMA Smart control application (Android / iOS) installed on any portable device (e.g. smartphone or tablet) that allows you to connect to the Wi-Fi network. From a single mobile device, you can control any number of Smart series devices, both locally from home and externally, via the Internet. The Smart system consists only of heating devices and sensors, and no additional control module is required (note: this is not compatible with Amazon Alexa, Google Assistant and IFTTT). No hub
