Ruskin model Z2000RT modulating zone thermostat with auto changeover comes standard with the models ZDS15, ZDR25 and ZDD25. Wire the thermostat directly to the zone damper logic board for stand-alone zone applications. When using multiple dampers in a single zone, one thermostat should be wired into the logic board of the primary zone damper. Subsequent tracer dampers may be ordered without the logic board and duct sensor. The tracer dampers will replicate the damper position of the primary damper.
