This menu contains the list of probes and some values that are automatically evaluated by the board
such as the superheat and the percentage of valve opening.
"nP" or "noP" stands for "Probe not present" or "Value not evaluated", "Err" means "Value out of
range" or "Probe damaged, not connected or incorrectly configured".
