phase where the food products are cooked. Time1 indicates and controls the len th of the steam
phase in minutes and seconds. Durin this phase the ventilation flap is closed.

Cookin Phase 2: Temp2 controls tar et temperature that can be used for re ulatin a second
steam phase, in this case if a different tar et temperature is needed durin a cookin pro ram.
Time2 indicates and controls the len th of the steam phase in minutes and seconds. Durin this
phase the ventilation flap is closed. In most of the standard cookin pro rams, this phase it is not
