Note: The ‘+’ and ‘–‘ keys have a repeat function: holding a key
pressed down will increase or decrease the power setting by
one level every 0.3 seconds.
To shutdown a cooking zone:
Press the relevant ‘–‘ key to reduce the power to 0.
Rapid shutdown:
To quickly switch off a selected zone press the ‘+’ and ‘–‘ keys
simultaneously: this will immediately switch off that zone
(Fig.2-9).
Note: After a zone has been switched off an ‘H’ may appear in
the display. This is a residual heat indicator showing that the
cooking zone temperature is above 60°C and may still cause
burns. Once the temperature has dropped to below 60°C the
‘H’ will go out.
To switch off all cooking zones:
All of the cooking zones can be immediately switched off by
pressing the On/Off key. Any ‘hot ‘ zones that were in use will
show an ‘H’ in the display (Fig.2-10).
Operating a double element:
Two of the cooking zones have dual elements and are
controlled by the Dual Element key (Fig.2-11), which will
toggle the setting on and off. To activate the dual element
setting press the Dual Element key once (a light above the
key will illuminate); press the key once again to switch off the
dual element.
Operating the triple element:
The triple zone has three settings – dual, triple and off – and
these are operated by successive operations of the key
(Fig.2-12). Press the key once for the dual element setting (a
single light will illuminate); press it once again for the triple
element setting (two lights will illuminate) and press it again
to switch back to a single element.
Preheat Function
This function allows for rapid heating up of an element
to bring a selected cooking zone up to temperature. The
element will operate at full power until the cooking zone is
at the required temperature then the power level will reduce
automatically to the preset level.
To activate the preheat function:
The preheat is activated automatically by pressing the
relevant ‘+’ key when selecting a cooking zone. A red ‘dot’ will
illuminate on the selected display to indicate that the preheat
is operating (Fig.2-13). Using the ‘–‘ key, set the preset power
level. When the zone is up to temperature the dot will go out.
To adjust the preheat power level:
The preheat level can be adjusted by pressing the relevant
zone controls: press the ‘+’ key to increase the power level
and the ‘–‘ key to reduce the power level.
