As part of the advanced development of intelligent home electronics, the operation aesthetics of such devices have also come to the fore. The design of the Nest Thermostat E for Europe blends together inviting curves, warm colours and an emotionalising user interface. Reduced to a display showing only the current temperature and the target temperature, this thermostat impresses with its soft and attractive appearance. When approaching it, the Nest Thermostat E automatically comes alive. By simply turning the thermostat ring, users can intuitively raise or lower the temper­ature. Moreover, changing the temperature is easily possible by voice control using Google Assistanten­abled devices and via Nest smartphone apps. The device boasts proven energy-saving features and allows operating with a simple, adjustable schedule. In addition, the temperature can also be changed from anywhere via the Nest app. Thus, the thermostat offers users a clear guidance to its functionality as well as versatile ease of use. Another benefit is that retrofitting pre-installed heating systems with Heat Link E requires no access to the boiler, as the device can be installed easily using previous thermostat wires. Coming with a practical mount, the Nest Thermostat E can be placed wherever users desire for optimum control comfort.
