goes to the fault switch-off. The waiting pro-
gram state is triggered by a lack of gas or an
open safety chain.
*4) The start help valve can be switched on
and off at any time (parameter). However it
must be activated with the beginning of the
state "Waiting for gas pressure" at the earli-
est and during the valve test after a regular
switch-off at the latest.
*5) The GDW VPS is monitored during the
valve test. Additionally, the parameter P46
can define whether the minimum pressure
monitoring via GDWVPS during operation
between state 17 and state 25 is active or not.
*6) The flame is detected here and must be
generated in this state at the latest.
