Speedcook Power Levels

Lower Heater

Advantium uses power from a high-intensity
halogen light, ceramic heaters, and microwaves
to cook food from the top, bottom, and interior
simultaneously, sealing in moisture and fl avor.

When using preset Speedcook recipes on the food
menu, power levels are preselected. However, these
power levels can be adjusted before or during
cooking. Also, the manual cook feature allows you
to speed cook items not on the preset food menu
by selecting your own cook time and power level
settings.

Each power level alternates heater power and
microwave energy throughout the cook time.
Percentage times of each power source vary,
dependant upon which power level has been
selected. The halogen light and ceramic heaters will
cycle on and off during a speedcook cycle, even
when full power has been selected.

UPPER POWER (U) controls both the upper heating
assembly and microwave power. A higher UPPER
POWER setting will utilize more upper heater power,
browning food faster on top. A lower UPPER POWER
setting utilizes more microwave power, causing food
to cook more evenly throughout. Select a higher
setting for such foods as pizza and baked goods.
Select a lower setting for foods such as casseroles,
meats, and fi sh.

LOWER POWER (L) controls the lower heater. Select a
higher setting to brown foods more on the bottom.
Select a lower setting for less browning on the
bottom.

Refer to the Speedcook Power Level Chart in
this chapter for specifi c power source operating
percentages.

Upper Heaters

The upper heating assembly consists of a 500 watt
halogen heater and a 700 watt ceramic heater. The
halogen and ceramic heaters provide radiant heat,
which browns the outside of the food while sealing
in moisture and fl avor. These heaters only operate in
the speedcook mode and always cycle on and cycle
off at the same time.

The lower heater is a 375 watt ceramic heater.
It operates in speedcook, oven/bake, and warm
modes. The lower heater assists in browning foods
on the bottom.

Microwave Energy
Caution: When cooking in Microwave mode, always

use the glass tray.

The Advantium 120 provides 975 watts of
microwave power, which is delivered directly
into the oven cavity to work independently, or in
conjunction with other cooking cycles. As the food
rotates on the oven turntable, microwave energy is
evenly distributed to all portions of the food.

Sensor Cooking

Advantium’s Microwave mode features sensor
cooking, which automatically selects cook times
and power levels. A humidity sensor detects the
increasing humidity released during cooking, senses
when the food is done, and shuts the oven off at the
appropriate time. Sensor cooking is not available for
5 minutes immediately following Speedcook.

Voltage Compensation
Note: Voltage compensation only occurs when

using a preselected menu item in Speedcook. These
items require compensation for accurate and
consistent cooking results.

Voltage fl uctuations in the power supply can cause
inconsistencies in cooking. The main PCB measures
line voltage at the start of each Speedcooking
selection and adjusts the cooking time to achieve
consistent results. Optimal line voltage, where no
voltage compensation occurs, is 120 VAC. Above
120 VAC, time is subtracted from the recipe. Below
120 VAC, time is added to the recipe. The amount of
voltage compensation required is dependent upon
the incoming voltage at the start of the cooking
cycle and the particular speedcooking selection that
is chosen.

The convection heater, located at the rear of the
oven, operates when using bake mode.

(Continued Next Page)

The following chart shows the predicted
compensation times based on a 12-minute
speedcook selection (such as Biscuits, Refr; Large).

Voltage Compensation Chart

Thermal Compensation
Note: Thermal compensation only occurs when

using a preselect menu item in Speedcook. These
items require compensation for accurate and
consistent cooking results.

126 -63
128 -84
130 -105
132 -126

Note: Voltage compensation should be within 20

seconds of values in table.

Voltage compensation occurs after approximately 5
seconds of cooking operation. The display will show
OPTIMIZING COOK TIME. The time will fl ash and
then display the new adjusted time, based on the
amount of voltage compensation required.

When cooking several food items consecutively, the
temperature in the oven may become very high.
When Speedcooking, the Advantium automatically
compensates for the increased temperature by
reducing the amount of time the upper and lower
heaters are on during each 32-second duty cycle.

At the start of each new Speedcooking operation,
the cavity thermistor reads the oven temperature
and sends this information to the main PCB board.
If the oven temperature is 150°F or higher, the
main PCB board will initiate thermal compensation.
Thermal compensation will reduce the amount of
time the heaters are on in each 32-second duty
cycle. The reduction in heater time is based on the
oven temperature at the start of Speedcook. The
higher the initial cavity temperature, the less time
the heaters will be on per duty cycle.

Thermal compensation occurs only once, at the
beginning of a Speedcook cycle. In the following
thermal compensation chart, the fi rst column lists
the initial cavity temperature, the second and third
columns list the number of minutes and seconds the
unit will have thermal compensation active.

Thermal Compensation Chart

Voltage compensation only occurs during
Speedcook operation and only occurs once during
the cooking cycle (at initial start of Speedcook
operation).

Thermal Protection

Thermal protection is a safety feature built into the
Advantium’s software. In the event that the internal
oven temperature reaches 500°F, the thermistor will
communicate this information to the main PCB and
thermal protection will be initiated. While in thermal
protection mode, cooking cycles will be maintained;
however, heaters will not be utilized until the oven
reaches the proper operating temperature.
