Function

The ZSR101 single zone switching relay is operated by low

voltage thermostats. 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 provide a

clean and professional installation.
