Shelly LinkedGo is a smart wall-mounted thermostat specially designed for precise control of underfloor heating systems. The device controlled by the ShellyX chip enables the direct control of heating valves and the switching on and off of heat sources (gas boilers, pellet stoves) via a potential-free relay. It is also compatible with electric underfloor heating systems, using a Shelly relay.

The thermostat has a built-in humidity sensor and a frost protection function that prevents damage to the pipes during long absences. It connects to your home network via Wi-Fi and Bluetooth without a hub and allows you to set smart timings and scenes using the Shelly Smart Control app.

The Shelly LinkedGo thermostat is the ideal choice for those looking for an energy efficient and smart solution to control their home or commercial hot water underfloor heating systems.
