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 paragraphs. The basic procedure for accessing each data
log is described in paragraph 9.3, step 7.
8.4.1
Fault Log
The C-More Control Panel logs the last 10 faults (0 – 9) 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.
