Features

    Taco's SR502-4 is a two zone pump switching relay. With universal thermostat compatibility, it is designed to integrate quickly and effortlessly into any hydronic system, bringing Taco reliability to your zoned operations. The SR502-4's enclosure is unobtrusive and easy to mount in tight spaces, and the PC board was designed for quick maintenance and clean, simple wiring.
  • Simple Servicing
  • Easy-to-interpret external diagnostic lights and "ice cube" style replaceable relays mean that servicing a Taco switching relay is always easy.
  • Protected Priority Switching
  • With the SR502-4, a single zone may be designated as a priority zone whose heating demands are given precedence over other zones. Other demands will be met when the priority zone is satisfied or after sixty minutes of priority operation.

Product Questions Answered by Ken, the eComfort Product Expert
Have a Lochinvar boiler with a DHS tank and one circulator pump feeding an air handler. Need to add another line with a 2nd circ pump. Will this SR504 work? That will give me 4 pumps then, the hot water, boiler, and the two circs. If this one won't work what would you suggest.
