Sequence of Operation
1. Preheating
When the power switch is turned on the burners light and raises the cavity
temperature to 200°F (the set point). No cooking mode has been selected and the
display shows SELECT MODE on the first line and PREHEAT on the second line.
When the power switch is turned on from a cold start the unit turns on the center
burner first and the cavity fan is off to allow the flue to heat gradually. After a few
minutes all three burners will light.
When the temperature rises above 180°F (20
°
F below the set point) PREHEAT
disappears from the display. The fan is allowed to operate at the selected speed.
The temperature continues to rise to the set point at which time the burners will
cycle on and off to keep it there. At any time the user may select any cooking
mode. However, if steam or combo modes are selected water will not enter the
reservoirs until after the unit is heated.
2. Flame-out detection
When the oven is started the cavity temperature should rise above 135
°
in ten
minutes. If the burner didn’t start or has gone out the temperature at that time will
be too low. The message “Burner not on. Relight” will be displayed and the oven
will turn off. Follow the RE-LIGHT instructions.
3. Ready indication
The ready condition is satisfied (the oven is ready) when the set cavity temperature
is reached. In the idle condition (no cooking mode selected) the set point is 200 ° F.
In steam mode it is set to generate steam. In combo and oven modes it is set
by the user. When the oven is not ready, the word PREHEAT is displayed and
the temperature display flashes. Once the oven comes up to ready PREHEAT
disappears and the temperature display stops flashing. If the door is opened and
the oven is loaded with cold food the cavity temperature will fall. However, since
the ready condition has already been met the temperature display will not flash.
If the cooking mode is changed then the temperature display will resume flashing
if the current cavity temperature is more than 20
°
F below the new set point,
that is, the oven is not ready. Once ready state is achieved with the new settings
the flashing will stop. The same sequence occurs if the temperature setting is
changed.
4. Water level
If combo or steam mode is selected one or more of the reservoirs will fill with
water (after the unit is heated). There are two water level sensor probes, one for
the center reservoir and one for the right reservoir. When the water level drops
below a sensor probe (boils off) the associated water valve opens and refills the
reservoir. Whenever a fill or drain valve is first opened a timer controls the fill and
drain times. If the water level has not changed when this timer finishes an error
message is displayed telling which valve (fill or drain) in which reservoir (1 or 2)
took too long to change. If it takes too long to fill or drain a reservoir it could mean
that the sensor probe is contaminated and should be cleaned. Fill timeout could
also mean that the water pressure is very low or the main water valve is turned
off. Drain timeout could mean that the drain is plugged and should be cleaned.
