MULTILINK is a purpose-built wireless switching solution for underfloor heating applications, designed to eliminate the need for traditional switched live cabling between multiple manifolds and a central boiler or pump. It provides a simple, reliable alternative where wiring is missing, impractical, or too costly to install.
Operating as a many-to-one wireless link, MULTILINK enables up to 10 transmitters—installed at individual manifolds—to communicate with a single receiver at the heat source. When a switched live signal is detected at any transmitter, a secure RF signal is sent to the receiver, activating the connected boiler, pump, or heating output.
Using advanced RF and LoRa spread spectrum technology, the system delivers long-range performance of up to 3km line-of-sight (typically up to 500m in buildings), ensuring dependable communication across large properties and challenging environments. This makes it ideal for both residential and commercial installations, including retrofit projects where running cables would be disruptive.
Designed with installers in mind, MULTILINK is quick to deploy, with straightforward pairing and operation. Its robust IP68-rated enclosure provides protection against water and dust, ensuring reliable performance in demanding environments such as plant rooms or outdoor installations.
By removing the need for complex wiring, MULTILINK reduces installation time, labour costs, and disruption—offering a flexible and efficient solution for modern underfloor heating systems where traditional cabling is not an option.
