6.3 Control panel
There are four variables that can be adjusted by the user: time, temperature, humidity and speed of the turbines.
These variables depend on the type of food and the quantity in the oven.
Temperature:it is regulated using the knob, from 50 ° C to 250 ° C. If your appliance is heating by resistance,
the white LED will light next to the knob.
Time:it is regulated using the knob, from 0 to 120 minutes, although there is a non-stop mode. which makes
the device work whenever the door is closed (is represented by the symbol of an open hand). If your appliance is working,
amber led located next to this command will turn on.
At the end of the cycle and powering the device, the oven beeps.
You can also set infinite cooking time. To do this, turn the encoder and program “INF” on the display. Then press
to confirm.
Humidity: is controlled by injecting water into the turbines, and generating steam to avoid food drying. It’s
possible to regulate the value of the humidity between 0 to 100%. This regulation takes continuous moisture injection
cycles, depending on the programmed percentage. For continuous functioning turn the knob to the left to 100%.
