Probe Self Detect - Honeywell ICON-343C User Manual

ICON 343C / 363C USER GUIDE
EN2B-0004UK07 R0304
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%.
This function only applies from initial power up of the controller. If
both the AIR-ON and AIR-OFF probes are fitted and the AIR-ON
probe becomes faulty, then the controller will continue to function
using the AIR-OFF probe, and the power to the controller would
have to be cycled off and then on again.
