8.4 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 water heater system.
Descriptions of these data logs are provided in the following sections. The procedure for
accessing specific data logs is described in section 8.3, step 10.
8.4.1 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 8-1.
NOTE
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.
