ELECTRIC COMBI OVEN - ELECTRICAL OPERATION
Page 51 of 68
Steam Mode
1. Conditions exist as described in “POWERING
CONTROL”.
2. With the selector knob rotated to STEAM, the
cooking cycle begins..
A. Time LED is on and “- -:- - “ is displayed in
the time display.
B. Cavity set point temperature (default) is
displayed in the temperature display. If the
oven has not been turned off, the previous
set point temperature is displayed.
C. With the water at the proper level in the
steam generator, steam generator heating
elements are energized and cycle as
described in “STEAM MODE” under
“STEAM REGULATION”.
NOTE: When degree symbol shows in the
temperature display, steam generator heating
elements are energized.
1) If oven cavity temperature is below
set point temperature, the steam
generator heating elements turn on at
full power until steam temperature is
reached, then turn off.
2) If oven cavity temperature is above
set point temperature, the oven
performs an automatic cool down as
described under “WATER
INJECTION (HUMIDIFIER)”, then the
steam generator heating elements
turn on.
D. Drain cool down solenoid energized.
NOTE: Whenever steam generator heating
elements are on, the drain cool down solenoid
is energized.
E. Cavity fan motor(s) energized.
3. Press the temp key to set the operating
temperature. The temperature symbol (°F or
°C) will flash in the temperature display to
indicate the cavity set point temperature can be
adjusted. The default temperature displayed
(195 to 212°F) is pre-selected in the
configuration mode and is the steam
temperature setting (boiling point adjustment)
for elevation. The adjustable operating range is
35 to 212°F. See “CONFIGURATION MODE -
MANUAL CONTROLS” under “SEQUENCE OF
OPERATION”.
A. Rotate the adjustment knob clockwise or
counterclockwise to adjust the setting
(temperature symbol stops flashing).
1) If a pause of 5 seconds is made
during or at the end of the
adjustment, the temperature symbol
will begin to flash. When the
temperature symbol stops flashing,
the temperature can no longer be
adjusted and the cavity set point
temperature is displayed.
NOTE: To display the actual cavity
temperature for several seconds, press and
hold the temperature key.
4. Oven control monitors cavity temperature and
cycles the steam generator heating elements
as necessary, to maintain set point
temperature.
A. The operating temperature remains as
entered unless the operating temperature
setting is changed or the oven is turned
off.
Combi Mode
1. Conditions exist as described in “POWERING
CONTROL”.
2. With the selector knob rotated to COMBI, the
cooking cycle begins.
A. Time LED is on and “- -:- - “ is displayed in
the time display.
B. Cavity set point temperature (the last
temperature that was set) is displayed in
the temperature display.
C. Deluxe Manual Control - COMBI key LED
turns on and 3 LED’s in the combi window
turn on, indicating the default steam factor
setting of 20.
1) Press COMBI key an additional 1 to 3
times to increase the steam factor
setting from 30 to 50. With each
successive key press, an additional
LED illuminates to indicate the
setting. This will be the “new” default
combi setting until manually changed.
D. Standard Manual Control - A fixed steam
factor setting of 20 is used. The combi key
and the combi window are not present on
this control.
E. Convection heating elements energized
and cycle as described under “HEATING
REGULATION”.
F. Steam generator pre-heats (initial start up
only) as described under “STEAM PRE-
HEAT”.
NOTE: When degree symbol shows in the
temperature display, convection and/or steam
generator heating elements are energized.
