The Superheated steam programme is a combined cooking programme in which steam is
fed in at the beginning until the saturation limit is reached, and is then superheated when
the convection heater automatically activates.
After selection of the programme, steam generator heating 13 is activated via contactors
K1, K2 and K3 and in gas units the steam generator burner 14 is activated via the
automatic firing N21, until the bypass temperature (bypass temperature probe B5 at the
end of the bypass pipe 5) reaches the nominal temperature (Service programme c08).
The convection heating 11 / convection heat exchanger 6 then continues to heat until the
oven probe B6 reports to the electronic circuitry that the pre-set temperature has been
reached.
Even when the heaters are then added, the steam generator heating 13 / steam
generator burner 14 have priority over convection heating 11 / convection burner 6.
The motor 12 runs continuously in reverse operation in this programme via the contactors
K5 and K50.
The programme is stopped automatically when the time or the pre-set CTC (Core
temperature probe B10 ) temperature is reached.
