ICON 343C / 363C USER GUIDE 6.5. Probe Self Detect The Icon 300 series has a feature that allows only the AIR-OFF probe to be fitted. If this function is used then the controller will not alarm on any probes that are missing. Again, this applies to the AIR OFF probe if this is the only probe that is fitted, and therefore the weighting parameter pair must be set to 0%. -
