Control modes
„Moist Heat“ mode
The high-performance steam generator produces fresh steam. This is fed, unpressurised, into the
cooking cabinet and is circulated at high speed by the fan. The patented control system regulates
the input of steam, supplying only as much as the food is actually able to absorb. In this mode
cabinet temperature is set to a constant 100 °C.
„Dry Heat“ mode
Powerful heating elements heat the dry air. The fan circulates the hot air evenly throughout the
cabinet. Cabinet temperature can be set to between 30 °C and 300 °C.
„Combi-Steam“ mode
Moist Heat and Dry Heat modes are combined by a control system. This creates a hot, humid climate
for especially intensive cooking. The temperature can be set to between 30 °C and 300 °C.
The humidity is controlled continually to prevent the food drying out.
„Vario-Steam“ mode
An electronic control system with temperature sensors accurate to one degree maintains the prese-
lected temperature throughout the cabinet. Sensitive controls and automatic control engineering
ensure that the cooking climate is just right for the product. The cabinet temperature can be variably
set to between 30 °C and 99 °C.
„Finishing
®
“ mode
The two operating modes moist heat and dry heat are combined. This produces the ideal cook-
ing climate, both preventing the food drying out and the formation of unwanted puddles. Cabinet
temperature can be individually set to between 30° C and 300 °C.
