P5 Tests - Air Stream Sensor Tests: Tests the validity of the Air Stream Sensors.
| P5-3 Evaporator Fan Direction Test |
| If configured for three phase evaporator fan motors: With evaporator fan running on high speed, measure the temperature difference between the primary supply and primary return probes. Turn the heaters on for 60 seconds then measure the temperature difference between the primary supply and primary return probes for up to 120 additional seconds. This is a Pass/Fail test. The test passes if differential of STS is 0.25 C higher than RTS. Test P5-0 must pass before this test is run. |
