Taco SR506 6-Zone Switching Relay W/Priority Function

​The Taco SR506 Switching Relay operates as a six-zone controller which allows users to manage independent circulator pump operations for hydronic heating systems. The controller enables users to establish priority settings between zones so domestic hot water takes priority over others for efficient system operation. The part includes external indicator lights which provide quick diagnostic feedback to make installation and maintenance easier. This part operates with conventional and programmable thermostats through its universal thermostat integration capability. The part offers better reliability and operation through its small size and easy wiring system combined with fuse protection and snap-out relays inside an enclosed unit.
