Priority Zoning Circulator

The Taco Priority Zoning Circulator combines the reliability of the 00 circulator with the convenience and efficiency of a PC board-mounted switching relay package.

Each zoning circulator has low and high voltage terminal strips for ease of electrical hookup as well as a built-in priority switch. The priority switch allows the installer to choose the zone that requires the most attention and, when activated, run only that circulator.
