P10-0 Carrier Controller Pre-trip Test Codes

P10-0 Frozen Mode Heat Test

If the container temperature is below 7.2 C, the setpoint is changed to 7.2 C., and a 180 Minute timer is started. The control will then be placed in the equivalent of normal heating. If the container temperature is above 7.2 C. at the start of the test, then the test proceeds immediately to test 10-1. During this test, the control temperature will be shown on the right display. The test fails if the 180 Minute timer expires before the control temperature reaches setpoint - 0.3 C. If the test fails, it will not auto-repeat. There is no pass display for this test. Once the control temperature reaches setpoint, the test proceeds to test 10-1.
