6.3 Calling the Checksums
If changes of parameters was done, you must reset the ETAMATIC OEM to update the CRC
checksum.
If you have two customer interfaces connected, you can only call the checksum, if the key
CHANGE DISPLAY is pressed simultaneously on both customer interfaces for a long time or
if one customer interface is disconnected temporarily.
6.4 Calling up the Hour Counter
The running times for curve set 1and curve set 2 do not necessarily add up to the displayed
total running time
NOTICE
The total counter refers to the ETAMATIC OEM's running time. It starts timing as soon as the
unit is connected to a voltage source (this also provides the basis for the fault history).
The individual running time counters refer to the burner's running time. They start timing as
soon as the burner is in operation with the relevant curve set (flame signal is present).
