P5 Tests - Air Stream Sensor Tests: Tests the validity of the Air Stream Sensors.
| P5-2 Return Probe Test |
| For units equipped with secondary return probe only. The temperature difference between return temperature sensor (RTS) and return temperature sensor (RRS) probe is compared. Test passes if temperature comparison falls within the specified range. NOTES 1. If this test fails, “P5-2” and “FAIL” will be displayed. If both Probe tests (this test and the SUPPLY/RETURN) pass, because of the multiple tests, the display will read “P 5,” “PASS.” 2. The results of Pre-trip tests 5-0, 5-1 and 5-2 will be used to activate or clear control probe alarms. |
