Taco SR503-EXP Three Zone Pump Switching Relay with Priority and 3 Powerports
Taco Switching Relays combine clearly-labeled PC board layouts with
advanced features that allow you to completely customize your system.
Whether you’re using basic priority switching, Taco Plug-In
PowerPort Cards or add-on power controls, tailoring the system has
never been easier. External indicator lights give you instant
diagnostic feedback, making service calls or new installation start-ups
a snap.
All switching relays are UL listed, use standard "ice cube" replaceable
relays and are compatible with conventional and programmable
thermostats. For larger jobs, switching relays can be expanded up to 20
zones with priority.
With the exclusive Taco PowerPort Plug-In Cards, you can easily add
such features as post purge, priority protection and pump exercise. Any
expandable switching relay can also interface with the Boiler Reset
Control and Injection Mixing Add-On Power Controls.
Mix-and-match as
needed to customize the system.
