Note 1: The generic binary output (TB4-1, TB4-2) state is unaffected by all unit diagnostics.
Note 2: When the entering water temperature is required but not present, the Tracer ZN520 controller generates a diagnostic to indicate the sensor loss condition. The

controller automatically clears the diagnostic once a valid entering water temperature value is present (non-latching diagnostic). When the entering water
temperature sensor fails, the controller prohibits all hydronic cooling operation, but allows the delivery of heat when heating is required. In the Cool mode, all cooling
is locked-out, but normal fan and outdoor air damper operation is permitted.

Note 3: When the outdoor air temperature sensor has failed or is not present, the Tracer ZN520 controller generates a diagnostic to indicate the sensor loss condition.

The controller automatically clears the diagnostic once a valid outdoor air temperature value is present (non-latching diagnostic). When the outdoor air temperature
sensor fails or is not present, the controller prohibits economizer operation.
