Notes:

1.The Tracer ZN010, Tracer ZN510, and Tracer ZN520 are factory-provided controls that control the end devices listed in the table.

2.The control interface option is the wiring tied back to a terminal strip to be controlled by a field-supplied controller.

3.Units with a DX coil are provided with a DX cool relay if unit has the control interface or Tracer controls.

4.Contact the factory for recommendations regarding steam coil valve selections compatible with Tracer™ ZN controllers.
