772 1 2 Dicht.Zü Leak check before ignition (0-OFF / 1-ON) 0 1 1
Setting of the leakage test before ignition:
0 = leakage test is off before ignition
1 = leakage test is on before ignition
This parameter is only of significance if the leakage test
is activated with an FMS. (Parameter 3)

Short Text Description Min Max Default
787 1 1 Wartung Maintenance mode (control unit only until stabilization
time)
020
0 = maintenance mode on (main valves are opened)
1 = maintenance mode active
2 = curve set switch allowed in set mode
Set the maintenance mode with this parameter. The
maintenance mode sets the pilot burner or the ignition
flame monitor. It enables to do 5 consecutive ignition
attempts without restarting with pre-purge and the leak-
age test. The burner sequencer only steps up to the
flame stabilisation time. You may not open the main
valves before the reset of this parameter.
After the 5
th
attempt pre-purge and leakage start auto-
matically.
Note:
A "Total Reset" resets the counter for maintenance
mode automatically i.e. the next cycle is treated as the
first and pre-purge and the leakage test are running.
Therefore, reset faults with a "Partial Reset" wherever
possible (selection switch on "Status", first channel key
2 upwards, then in addition channel key 1 downwards).
Attention: You may not use a partial reset for some
faults.
