Thermal Compensation
Thermal compensation only occurs once and
Note:
only when using a preprogrammed 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 power levels based on the following
rules during each 32-second duty cycle.
• Thermal Compensation occurs only ONCE and
when using a pre-programmed recipe.
• Activates when oven cavity temp is greater than
220°F.
• Compensation rules:
UPL = Upper Power Level,
LPL = Lower Power Level,
CPL = Convection Power Level.
• No compensation if cook time is less than 2
minutes 30 seconds or greater than 13 minutes.
• If cavity temp less than 220°F, no compensation.
• If cavity temp greater than 220°F but less than
288°F, reduce UPL by 1, LPL by 2, and CPL by 2.
• If cavity temp greater than 288°F but less than
340°F, reduce UPL by 1, LPL by 3, and CPL by 2.
• If cavity temp greater than 340°F, reduce UPL by
1, LPL by 3, and CPL by 3.
• Upper thermal sensor (blue and white wires) is
used for thermal compensation.

Proof Feature

The purpose of the PROOF feature is to help dough
rise at the correct temperature inside the oven. To
activate the proof feature, press the
pad, then turn the dial to
the dial to start. The following will occur:
• The convection fan and convection heater come
on immediately.
• The convection element cycles 11 seconds
on and 21 seconds off for fi rst 30 minutes at
temperature around 80°F, then after 30 minutes
element is 100% on only if the temperature is
below 80°F and cavity is calling for heat.
• The convection fan continues to operate and, if
needed, the convection heater will come on.
In PROOF, there is not an upper temperature
Note:
set point defi ned. If the temperature is above 80°F,
then the element does not come on at all until the
temperature is below 80°F. (Ideally you don't want
a temperature over 100 - 110°F because you will
kill the yeast.) But unless there is something wrong
with the oven control, the element, or the actual
environment is above 100°F, PROOF should never
reach this condition. If an inoperative convection
heater in the PROOF mode is suspected:
1. Disconnect power.
2. Remove the rear access cover.
3. Remove the thermistor from the convection
heater assembly.
4. Lower the thermistor temperature by placing a
chilled or frozen item against the thermistor.
5. Connect power and enter proof mode.
6. Check for approximately 120 VAC (12.3 Amps) at
the convection heater.
