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.
