The Caleffi ZVR104 Multi-Zone Valve Relay is an electronic control module that manages multiple heating zones in hydronic systems by coordinating signals between thermostats, valves, pumps, and boiler operation. It processes low-voltage inputs and distributes switching commands to activate zone valves and circulation components as required, and HVAC systems rely on this coordination to maintain balanced heat delivery across different areas. It is placed in the system control panel, it acts as the central switching interface that organizes zone demand, ensures proper pump activation, and supports stable, efficient heating system performance across multi-zone configurations.
