Supporting reliable hydronic zoning, the ZSR103 integrates three pump zones into one intelligent control module that streamlines wiring and system management. Priority zoning, LED diagnostics, and built-in transformer capacity deliver consistent performance in radiant, baseboard, or multi-zone hot-water systems. Its compact enclosure mounts cleanly in mechanical spaces and simplifies troubleshooting for installers and technicians.
