Output for the connection of ignition transformers or electronic ignition modules.
Gas
When firing on gas, ignition is switched on in phase 38 just before reaching safety time 1
(TSA1).
The preignition time in phase 38 can be parameterized.
No. Parameter
226 Gas: Preignition time
326 Fuel 1 gas: Preignition time
Oil
When firing on oil, there is a choice of short and long preignition (same as with gas).
No. Parameter
Oil: Point in time oil is ignited
281 0 = short preignition (Ph38)
1 = long preignition (with fan) (Ph22)
Fuel 1 oil: Point in time oil is ignited
381 0 = short preignition (Ph38)
1 = long preignition (with fan) (Ph22)
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
366 Fuel 1 oil: Preignition time
