💡 How does a priority controlled pump switching relay stay handy for hydronic boiler setups? Getting the circulation timing right is essential when multiple zones share a single burner loop. Here is why seasoned techs pick this switcher model every season: - Routing primary current to the DHW coil first keeps the hot water supply steady while radiators draw less load - Spreading the transformer duty across two loops stops the cabinet from tripping the breaker on heavy simultaneous calls - Dying contactors swap out fast since the terminal strip takes common ice cube modules for quick shop bench repairs
