Z-one™ Zone Pump Controller, Multizone and Single Zone - NA Market

The ZSR series is a zone pump and boiler operating control for single zone switching and multiple zone hydronic heating systems. The ZSR series interfaces with low voltage thermostats, or any other low voltage controllers having a switching action. The ZSR101 single zone switching relay incorporates Power In, Relay 1 and Relay 2 connection terminals to provide a convenient and cost effective way to control a circulator and a boiler operating control in a single zone hydronic heating system. The ZSR101 single zone switching relay saves hours in installation time and provides a clean and professional installation. The ZSR series multiple zone switching relay controls up to 6 zone pumps depending on model selected and a primary pump. It has LED indicators to provide functional status and easy system troubleshooting.
