You can also use this command to quickly lower the temperature in the cooking chamber: e.g. open the door and hold the button for more than 3 seconds. To ease this operation, the chimney is also opened and the fans are rotated at maximum speed; you can monitor the temperature decrease on display 2.

Manual Operation for preheating

Preheating enters into action, at the beginning of each cooking, both manual and automatic.

It consists of heating the cooking chamber to a given temperature.

Manual preheating will terminate when the oven reaches to the desired cooking temperature which is the sum of the set temperature and the 30° relative to the preheating temperature.

Pressing the START &- STOP button starts the preheating of the oven.

Upon reaching the set temperature the oven emits a signal sound and display changes from "PRE" to a flashing "END".

At this point, open the door (at which the signal sound stops) and put the food inside the oven, then close the door. When one opens the door display indicates OPEN. The oven will begin the cooking cycle and one can now set the cooking time and the manual humidification.

Manual Operation for START/STOP command

Press the key START / STOP button to start the baking cycle. This way you will activate the MANUAL function for heating, ventilation and humidification.

By pressing the key START/STOP you can block the baking cycle at any time. Press it again to restart the oven cycle from the beginning.

You can monitor the temperature decrease on display. The set baking temperature and time values remain available for a possible new baking.
