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
flash 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.
