Limited time of operation
To increase reliability of the plate each hot -
plate is provided with operation time limiter.
The maximal time of operation depends on
the last selected heating power level.
If the heating power is not changed during the
specified time (see the Table), the hotplate
will be switched off automatically and the
residual temperature indicator will be lighted.
If you want to continue cooking, switch on
the hotplate again at the required level of
heating power.

During the supply voltage drop the
„h“ is no more shown. In spite of
this the hot fields can be still hot!
Important! If the cooking plate is
started again after the renewed
switching on or after the supply
voltage drop, a short „self-test”
will be performed. The „h” will be
displayed on the residual heat in-
dicator during about 45 to 60 minu-
tes. The indication of residual heat
is not based on the measurement
of a value, but on the calculation
depending on the operating time
of hot fields.
OPERATION
Residual temperature indicator
When a hot plate has been switched off, letter “H” is displayed indicating that the hotplate is
still hot.
Do not touch the hotplate and do not
put heat-sensitive objects on it when
the “h” letter is displayed as you can
burn yourself or melt the object!
When the indication goes out you can touch
the hotplate, bearing in mind that it still does
not have ambient temperature.
After the pause caused by the supply vol-
tage drop the highest possible temperatu-
re and the longest cooling time are taken
into account and therefore the indication
time is so long lasting.
This is of no importance for the further
operation of the cooking plate.
