Function
The ZSR series is multi-zone pump and boiler operating
control for multiple zone hydronic heating or cooling
systems. The ZSR series interfaces with low voltage
thermostats, or any other low voltage controllers having
a switching action. The ZSR series controls up to
3, 4, 5 or 6 heating circulator pumps (depending
on model selected) a primary pump and has LED
indicators to provide functional status and easy system
troubleshooting. In addition, a primary pump system
circulator is switched on whenever any zone calls for
heat.
