E3 electrodes, once the fault gas (KA10) is validated by the ELECTROLUX ITS.
In order to protect the heating system, the B5 pressostat check the gas pressure and the B4
pressostat check the product of combustion.
The B126, B127 and B128 temperature sensor (PT100) contribute to the regulation of the
