Each Taco 007-ZF5-3IFC model Priority Zoning Circulator comes with a built-in transformer, relay and priority switch, so all the wiring is done directly to the circulator’s PC board instead of an external control (such as a switching relay), making it ideal for adding a zone or an indirect hot water heater.
The priority switch allows the installer to choose the zone that requires the most attention and, when activated, run only that circulator. Taco 007-ZF5-3IFC priority zoning circulator can be used in conjunction with other circulators or zone valves. This models also comes equipped with a built-in IFC (Integral Flow Check), which performs better than the standalone alternative and reduces installation time and costs.
