Output for the connection of ignition transformers or electronic ignition modules.
Gas
When firing on gas, ignition is switched on just prior to the first safety time in phase 38.
The preignition time in phase 38 can be parameterized.
No. Parameter
226 Gas: Preignition time
Oil
When firing on oil, there is a choice between long and short preignition (as with gas
operation from phase 38).
No. Parameter
Oil: Point in time oil is ignited
281 0 = short preignition (phase 38)
1 = long preignition (with fan) (phase 22)
When using long preignition, ignition is switched on in phase 22, together with the fan.
In the case of short preignition, the preignition time can be parameterized.
No. Parameter
266 Oil: Preignition time
