NOTE: These faults are not overridden by an alarm or warning condition, and always have
higher priority over all other faults. For all other faults, an alarm or warning
condition (gas reading) will override a fault being displayed.
If the two or more faults occur simultaneously, the Base Unit will display the higher priority fault.
