8.2 Check Sums - Hours of Operation
8.2.1 Calling the Checksums
Each of the parameter levels is safeguarded by its own checksum. The checksum for each
level and the safety and pre-purge times are displayed here in succession.
Order:
1
st
oil safety time in seconds
2
nd
oil safety time in seconds
1
st
gas safety time in seconds
2
nd
gas safety time in seconds
Pre-purge time in seconds
On the VMS without pilot burner the statement of the 2
nd
safety time contains safety time. The
statement of the 1
st
safety time is then irrelevant.
NOTICE
If the parameter has been changed, the checksum will change, too, if a total reboot has been
proceeded or the duration of 1h has passed.
Switch (1) to SETPOINT FEEDBACK
Press ENTER (3) and keep pressed
– the display shows the checksum and the safety
times one after the other.
CRC 16 level 0: adjustable without password
1: adjustable by person commissioning
2: adjustable by the burner manufacturer or the boiler manufacturer
3: adjustable by LAMTEC only
