Salus CB500 5 Zone Wiring Centre
Salus CB500 5 Zone Wiring Centre
The Salus CB500 is a robust, hard-wired wiring centre designed for precise and flexible control of underfloor heating or cooling systems across up to 5 independent zones. Its integrated module handles heat and cool sources, supporting smart switching between heating and cooling modes as required. The CB500 offers advanced, reliable control for a wide range of installations and is expandable to accommodate larger projects by adding CB500X extension modules (up to 15 zones in total).
