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

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.
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.

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.
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.
