thermio™ essential smart

PRODUCT DESCRIPTION

The thermio™ essential smart is a digital room thermostat of ErP class IV that can be programmed and operated easily and conveniently with a free app. Thanks to the integrated Bluetooth functionality, temperature profiles and schedules created on a mobile device can be transmitted and adapted easily and simply to the thermio™ essential smart via Bluetooth. This allows individual temperature profiles to be implemented easily, lowered automatically and thereby significantly reduce heating costs – without any loss of convenience. Of course the thermio™ essential smart can also be operated without the app: A large LC display and a manual ON/OFF switch make the room thermostat easy to operate.
