Recording error codes
In the event of a system failure, a continuous prompt tone will sound and the system
failure indicator will light. Before shutting off the unit and removing it from service,
make note of any error code that appears. The first two characters of the code will
appear in the % Relative Humidity display. The third and final character appears
on the Set RH bar graph display; 1 = the first segment from the bottom, 2 = the
second segment, and so forth. The error code will aid qualified service personnel
in diagnosing problems. For more information see Error codes in section 6 of this
manual.
