Smart HVAC thermostat LinkedGo - Powered by ShellyX
Description
The LinkedGo Smart HVAC thermostat is a versatile thermostat Powered by Shelly, able to manage a complete HVAC system from a single device: fan coil units, underfloor heating, ventilation and cooling. It supports control of AC and DC fans, including a 10V DC analogue signal, as well as a dry contact for signalling heat sources such as gas or pellet boilers.
The thermostat can be integrated both into home Wi-Fi installations and into larger HVAC systems via the RS485/MODBUS interface. The anti-freeze function protects the heating installation during long periods of absence, while the built-in humidity sensor and the temperature and humidity offsets ensure accurate readings.
Wi-Fi and Bluetooth connectivity eliminate the need for a hub, and the device can also act as a Wi-Fi signal extender or Bluetooth gateway. The thermostat is mounted in standard wall boxes of at least 70x70mm.
It is suitable for offices and commercial spaces with fan coil systems, for homes with underfloor heating and centralised ventilation, and for integration into an existing HVAC system controlled via RS485/MODBUS, where it can coordinate heating, cooling and ventilation from a single point.
Practical use cases
- In an office or commercial space with fan coil units, it controls AC or DC fans (including via a 10V DC analogue signal) and coordinates heating and cooling from a single point.
- In a home with underfloor heating, it signals the gas or pellet boiler via the dry contact, while the anti-freeze function protects the installation during long absences.
- Connected via RS485/MODBUS to an existing HVAC system, it controls heating, cooling and ventilation together with the rest of the installation.
- Used over Wi-Fi, without a hub, it can also work as a Wi-Fi signal extender or Bluetooth gateway.
