Open box Smart thermostat for underfloor heating LinkedGo - Powered by ShellyX
Description
What does "open box" mean?
Open-box products are returned products with opened or damaged packaging, but fully checked from a technical point of view and completely functional. They come with the same warranty as new products.
LinkedGo Smart floor heating thermostat is a Powered by Shelly smart thermostat dedicated to precise control of underfloor heating systems. The device directly manages the heating valves and can signal the heat source - gas boiler, pellet stove or other equipment - to switch on or off automatically.
The thermostat has a built-in humidity sensor and a frost protection function that maintains a minimum safe temperature when the occupants are away for a long time, and it allows the temperature and humidity offset to be adjusted for more accurate readings. It can also be used to control electric underfloor heating, signalling a connected Shelly relay to switch the heating on or off according to the set temperature.
Wi-Fi and Bluetooth connectivity removes the need for a hub, and the device also works as a Wi-Fi range extender and Bluetooth gateway for other BLU devices in the Shelly ecosystem.
It is ideal for homes with underfloor heating, for cabins or holiday homes where the frost protection function protects the installation during winter, and for automating the heating schedule based on time of day or sunrise/sunset.
Practical use cases
- Installed on an underfloor heating system or an HVAC system, it allows remote temperature adjustment and scheduling by time of day.
- It can automatically lower the temperature at night or when you are not at home, returning to a comfortable temperature before you wake up or arrive.
- It integrates with the rest of the smart home ecosystem for more complex automations.
- It offers finer climate control than a conventional mechanical thermostat, with consumption history available in the app.
