Wiring Panel Temperature: Measured using a sensor, located on the processor board.

NOTE:

The measurement from the PanelTemp() instruction does not accurately reflect the temperature of the wiring panel, since it measures the temperature of the main processing board. Therefore, if the data logger processor, or charge (CHG) input are active, the PanelTemp() measurement will be warmer than ambient. This should be taken into consideration if this measurement is used as a reference temperature for other measurements such as thermocouples.
