other one is in error.

4.9 SOFTWARE UPDATE & WIFI
The software update is not possible on the electronic boards. WIFI is not implemented at this moment.
NOTE !
If the filters start to get dirty and limit the fresh air passage, before
emitting an “over heating alarm
E421” the appliance will start to limit the energy emission of the POW, a typical call from a customer
could be “ the appliance is not performing any more” or “ after some time the appliance is not per-
forming”.
