Features
    Taco's SR501-EXP-4 is a single 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. Post purge and pump exercise operation modes will run your pumps briefly after calls for heat or long periods of inactivity. These improve the efficiency and dependability of your system, respectively. The SR501-EXP-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.
  • Expandable
  • Taco's -EXP switching relays may be combined with other relays or expandable Taco zone valve controls for large scale zoning applications. Up to 20 zoning panels may be connected together.
  • Add-On Power Controls
  • The SR501-EXP-4 is compatible with Taco's PC700 line of supplemental controls. It's easy to add outdoor temperature reset via variable speed pump mixing or boiler reset control.
  • Product Compatible With
  • Taco -EXP Expandable Zone Controls
