NOTE: When zoning with circulators, the furnished circulator pump should be used as one of the
zone pumps. Each stripped end of the electrical wires for the circulator pump inside the junction box
should be taped or wire nutted to prevent short circuits. Unplug the circulator pump wiring at the
integrated boiler control.
