Application
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. The priority zoning
circulator can be used in conjunction with other circulators or zone valves. It is ideal for
indirect hot water heaters, adding another zone, zoning with circulators, and for prioritizing
under-sized zones. Available in a full range of sizes from 003 - 0014.
Also look for Taco’s complete line of Switching Relays, Zone Valve Controls, and Hydro Air
Fan Controls, for all your single or multi-zone needs.
