the gas-heated ones using a fan-assisted or blast
burner, in which, owing to the time required for purging the
mixing chamber, the fume condenser can be started
only after a delay of 18 seconds.
SINCBOL °C 120
Boiler scaling alarm tripping temperature. Such a
parameter expresses the temperature value, as measured
by the boiler probe, which, when reached owing to the
thickness of the scale formed in the boiler, will cause the
controller to illuminate the boiler scaling alarm
indicator. The value of 120 °C has been determined
experimentally and corresponds to a scale thickness equal
to 1 to 1.5 mm.
SOFTSTRT - 0
Parameter for pre-setting manual/automatic mode. It is
operative in functional levels 6 only. It pre-sets the
manual/automatic selector in programmable ovens in
different modes after ignition or switching on, ie.:
- if set at “0”, the LEDs will blink to indicate that the operator
must do the setting;
- if set at “1”, it goes directly to the automatic mode;
- if set at “2”, it goes directly to the manual mode.
Switching over to the other cooking mode is anyway always
possible by simply pressing the same push-button.
sonVNTMX sec 30
Fan start delay. Such a parameter is operative in
steaming and thermostatically controlled steaming cycles
only and determines a forced pause phase of the fan, in
said cycles, when the oven door is being closed. Steam
generation starts on the contrary without any delay when
the door is closed again.
SPHBOL °C 85
Steam generator pre-heating temperature.
Temperature to which the controller pre-heats, and at
which it then maintains the water in the steam generator.
At lower temperatures, cycles using steam are interrupted
as long as such a value is not restored automatically.
sRIGBOL sec 50
sRIGCEL sec 100
Such parameters respectively express the duration of the
alternate operation periods of the boiler (sRIGBOL) and
the oven cavity (sRIGCEL) during the temperature rise
phase in reconstitution cycles. They are only operative
in models provided with boiler. An increase of sRIGBOL at
the expense of sRIGCEL will pre-set a higher moisture
content inside the cooking cavity, but at the same time
increases the time needed to reach the required
temperature value in the same cavity. An increase of
sRIGCEL at the expense of sRIGBOL brings about the
opposite effect. The related pre-set values have been
derived experimentally.
sRIGIMPVsec 10
Duration of steam pulse in reconstitution cycles.
Such a parameter is only operative in electric ovens
provided with boiler (no ISG) and expresses the duration
of a period of steam injection into the cavity, after the oven
door has been closed, in reconstitution cycles only.
SSCH °C 35
Value at which a cooling-down phase for the internal oven
components is started. Such a parameter expresses the
temperature value, as measured on the master board (POW
1 or POW 2), above which the controller causes the cool-
down fan to be switched on. The same fan will only be
switched off if the temperature decreases by at least 5 °C
below SSCH (with SSCH=35, this will therefore occur at
30 °C,
sVAPOFF sec 20
Shortest allowable duration of the OFF phase in steaming,
combined and reconstitution cycles. Such a parameter
serves the purpose of ensuring an off phase of the boiler
which has a minimum duration, while being anyway
sufficient to ensure the operation stability of the steam
control system (in the by-pass).
sVAPON sec 15
Shortest allowable duration of the ON phase in steaming,
combined and reconstitution cycles. Such a parameter
serves the purpose of ensuring an on phase of the boiler
which has a minimum duration, while being anyway
sufficient to ensure the operation stability of the steam
control system. In electric ovens, the correct value is 15
seconds; in gas-heated ovens with fan-assisted or blast
burner it is necessary (owing to the required preliminary
purging time) that such a value be increased to 30 seconds
(in the by-pass).
sWF2CLN sec 120
Duration of pause in “CLEAN” cycle. This pause phase is
provided to enable the detergent, which is sprayed in the
cavity by the operator at the end of phase 1, to develop
an adequate chemical effect. Such a pause is started
automatically upon reclosing the door, and its count-
down, in seconds, is shown on the oven cavity temperature
display.
TENDCLN °C 99
Temperature at which counting starts for the duration of
the phase 1 of the “CLEAN” cycle. The parameter ex-
presses the oven cavity temperature value that determines
the beginning of the phase 1 of the “CLEAN” cycle. Such
a phase is provided to ensure oven cavity pre-heating by
means of steam, thereby causing soil in the same cavity
to be “absorbed”.
TRAFCLN °C 90
“CLEAN” cycle cool-down temperature. Such a parameter
expresses the temperature value being measured in the
oven cavity, in correspondence of which the pre-cooling
phase, provided in the case that the “CLEAN” push-button
is pressed when the oven cavity is still rather hot, is caused
to terminate.
TSCBAMX °C 50
This parameter is operative only in those functional
levels that are provided with a power-actuatable boiler
drainage system. It expresses the temperature of the
water in the boiler, below which the controller enables
