The Salus Mains Switch is a highly efficient wireless RF module designed specifically to manage pump overrun functions within complex domestic and commercial heating systems. Operating as a practical substitute for traditional hardwiring, this 0.5kg receiver eliminates the costly and time-consuming requirement of routing extensive cable runs through finished walls and floors. By establishing a robust radio frequency connection with compatible system controls, it ensures that the circulation pump continues to operate after the boiler stops firing, safely dissipating residual thermal energy from the primary heat exchanger.

Constructed for rapid deployment, this cost-effective module integrates seamlessly into modern hydronic configurations to protect sensitive boiler components from potential overheating damage. The streamlined design offers a highly unobtrusive installation footprint, making it an essential tool for heating engineers looking to solve difficult wiring scenarios on retrofit projects. By facilitating a reliable wireless overrun protocol, it helps maintain long-term system integrity and ensures compliance with strict boiler manufacturer installation parameters.
