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".

Alarm description
Tesla POW: IGBT cooling fan blocked or not connected. Re-
marks:
• The alarm is reset when the U.I. stay at least 120sec of
OFF or COOLING_DOWN state, no matter if problem is
solved or not.
• About 20 sec before the alarm occurs POW sent pot fail
state to the U.I.
Foucault HC: One or more internal cooling fan blocked/not
connected/not following. Power disable depend on number of
fans blocked
Tesla POW only: External tangential fan blocked or not con-
nected.
Remarks: The alarm is reset when the U.I. stay at least
120sec of OFF or COOLING_DOWN state, no matter if prob-
lem is solved or not.
U.I1 detects POW1/POW2 communication timeout.
The alarm is showed on left display only (Both 821 and 822).
NOTE: This alarm maybe generated by:
➢ A wrong MACS connection between U.I and POW
➢ A missing or wrong ID jumper on POW board.
With appliance with more than one POW (e.g. Double Zone
Fry top) it's still possible to work with one zone only when the
other one is in error.
U.I1 detects MACS acknowledgements missing to POW1.
This alarm appears if communication is lost during standard
operation. The alarm is overridden by E821 after some sec-
onds. The alarm is showed on both display.
