REGULATION AND TRANSFORMATION
Display of the temperature inside the hob
There is a temperature sensor inside the electronic card with which it is possible
to show the temperature inside the hob directly on the timer display. The display is
activated by pressing the + and - buttons of burner 1 together with buttons 12 and
13 continuously for at least 3 seconds. In this condition it is no longer possible to
use button 11 for settings related to the programming of the burner switch-off time.
The same sequence of buttons used to activate the inner display of the
temperature must be used to deactivate it.
Electronic self-diagnosis
The electronic cards constantly control their own status. Should hardware problems
or faults inside the card occur, such as to jeopardise the safety of the end user, the
device enters a “safe” status in which the solenoids are switched off and a code
relating to the type of fault appears on the display.

All burners in lockout state
Loss of gas from valve which has
caused an unwanted ignition of another
burner. Flame detection on other burner
for more than 10 seconds, causes this
anomaly type
Replace faulty valve
Communication error in the logical core
Circuit breakdown
Replace device
Keyboard error
A mechanical deformation can
compromise support keyboard to glass.
Wait for few seconds until keyboard re-
calibration. If fault persists switch off
and switch on the main supply. If fault
still exists replace device
