Fuel selection
With dual-fuel burners you can switch between oil and gas operation. A fuel
change during operation will initiate a restart.
Fuel selection is possible via:
Fuel selection switch on input X4-01:1/2 [ch. 3.3.6]
Parameter fuel selection (ABE)
Building management system (BMS) on Bus connection.
The fuel selection switch on input X4-01:1/2 has priority. Fuel selection via ABE or

between ABE and BMS, the last fuel selection is valid and is retained after power
failure.
