USING THE ELECTRIC THERMOSTAT (left oven)
The thermostat supplied with the relative models maintains a constant temperature inside the oven at a specific
temperature setting ranging from 50°C to 250°C.(fig.17)
Turn the knob clockwise and align the selected temperature indicated on the ring with the index etched on the control
panel. Thermostat operation is indicated by an orange light which will turn off when the temperature inside the oven is
10°C greater than the temperature setting, and will turn on when the oven is 10°C less than the temperature setting. The
thermostat can control the oven elements only if the relative switch is in one of the possible oven element operating
modes: if the switch is in position 0, the thermostat has not effect on the oven elements, which remain off.
USING THE THERMOSTAT WITH SWITCH IN SERIES (Right oven)
(COOKERS WITH A SINGLE-CONTROL CONVENTIONAL ELECTRIC OVEN)
The electric oven is controlled by an electric thermostat combined with a switch used to turn on the elements. The
electric oven can be combined with an electric grill. The oven is heated by 2 elements: one on the top and one on the
bottom. Turning the knob clockwise (fig.18) in the first position we have the single operation of the oven light .
Turns on the bottom element and the top external elements while the thermostat is used to set the temperature ranging
from 50°C to 250°C. It can be adjusted using the scale indicated on the ring around the knob. An orange light turns off
indicating that the temperature setting has been reached. Therefore, it is normal for this light to turn on and off while the
oven is working. There are 3 fixed position beyond the 250°C setting:
- the symbol indicates the only the bottom element (900W) has been turned on;
- the symbol indicates that only the top external element (600W) has been turned on;
- the symbol indicates that only the grill element (900W) has been turned on;
In these positions the temperature is not controlled by the thermostat.
USING THE 9 + 0 SWITCH (left oven)
The 9 + 0 switch installed in the multifunction oven models is used, along with the thermostat, to control the electric fan
and the oven elements since they can be turned on by turning the 9 + 0 switch knob and the thermostat knob. Turning
just one of the two knobs will not have any effect on the oven except to turn on the oven light or the electric fan when
inserted. The electric oven is heated by 4 elements: one on the bottom, two on the top or one circular; turning the switch
knob (fig.19) turns on the element relative to the symbol indicated on the ring but to be activated the thermostat knob
must be turned until the orange light turns on indicating that the element has been turned on. Placing the switch knob on
any of the nine operating modes turns on the oven light, together with the relative element. Once the temperature and
the elements to be used have been set, the oven elements are turned on and off by the thermostat; therefore, it is normal
for the orange light to turn on and off while the oven is working.
To turn off the electric oven set the switch knob to position 0 to prevent the thermostat from controlling the elements.
Setting the thermostat knob to position 0 turns off the elements but it is still possible, using the switch, to turn on the
electric fan and the oven light.
The switch has 9 different fixed positions corresponding to 9 different types of oven operation:
- the symbol indicates that only the oven light is turned on;
- the symbol indicates that the bottom element (1300W) and the top external element (900W) have been turned
on;
- the symbol indicates that only the top external element (900W) has been turned on;
- the symbol indicates the only the bottom element (1300W) has been turned on;
- the symbol indicates that only the grill element (2000W) has been turned on;
- the symbol indicates that the top external element (900W) and the grill element (2000W) have been turned on;
- the symbol indicates that the top external element (900W), the grill element (2000W) and the electric fan have
been turned on;
- the symbol indicates that the circular element (2400W) and the electric fan have been turned on;
- the symbol indicates that only the electric fan has been turned on.
When the knob is set to one of these nine positions, the oven light is always on, thus indicating that the oven is being
energised.
