9.4 DATA LOGGING
During operation, the C-More Control Panel continuously monitors and logs data associated with
operational events, faults and sensor readings associated with the boiler system. Descriptions of these
data logs are provided in the following sections. The procedure for accessing specific data logs is
described in section 9.3, step 10.
9.4.1 Fault Log
The C-More Control Panel logs the last 20 faults (0 – 19) starting with the most recent (#0). They can be
viewed in the front panel display or via the RS232 port. The Fault Log cannot be cleared. If the Fault Log
already contains 10 faults, the earliest fault is overwritten when a new fault occurs. A sample Fault Log
display is shown in Table 9-1.

The Operation Time (T) Log can store thousands of records.
Therefore, to view the most recently logged record, enter "T"
followed by 0 (zero) and press Enter (i.e. T0 <Enter>). To view
earlier records in reverse chronological order, enter T and press
Enter. To go back 200 or 1000 records, enter T200 or T1000, etc.
and press Enter.
