Why Use This Cable?
If you’re integrating an external control system—such as Gecko in.grid or Balboa relay—into a Vian Nexus Evo 6 or 7 heat pump, this cable provides a safe, plug-and-play signal link. It ensures correct and reliable switching functionality without relying on alternative custom wiring or incompatible connectors. Importantly, the cable does not carry mains power—it only transmits signal switching logic, making it a low-risk, compatible interface for control integration.
