Table 6 describes the ERROR_NUMBER values for
Lockout Errors. These are errors that require a
manual reset to continue boiler operation. Table 7
describes the ERROR_NUMBER values for Blocking
Errors. Blocking errors are conditions that allow the
boiler to continue operation as soon as the condition
is corrected.
Table 7 shows values for the WARNING_NUMBER
holding register. These conditions primarily concern
the operation of sensors.
If multiple errors are present, the lowest number error
will be communicated.
