Diagnostics And Troubleshooting; Normal Operation Codes - Rheem *96V series Installation Instructions Manual

Below are two lists; a list of standard operating codes and
a list of fault codes. The fault code list provides diagnostic
and troubleshooting information to help determine the
problem and fix it. Standard operating codes are not fault
codes and the presence of a standard operating code indi-
cates a no-fault condition.
