The Taco 0010-SF3 is a stainless steel flanged priority zoning circulator that combines the reliability of the 00 series with an integrated switching relay package. It features a snap-in PC board, removable quick-connect terminal strips, and a built-in priority switch that allows the installer to designate one zone for priority operation such as an indirect water heater. The unit is ideal for adding a zone or prioritizing an undersized loop and works with standard 24V thermostats.
