GLOSSARY OF COMMON OPERATING TERMS
Off State
All the oven’s control systems are off and the cook cavity temperature is below 150
º
F (66
º
C).
Cool Down
A subset of the
OFF STATE. During COOL DOWN
, the oven will circulate the main convection blower until
the cook cavity temperature is below 150
º
F (66
º
C).
Ready State
The oven has successfully warmed to the predefined set temperature. At this point the oven control is
ready to receive cook commands via the keypad. The oven will maintain the set temperature in the
READY STATE.
Set Temperature, Cook Cavity (CCSP)
Predefined temperature of the cook cavity at which the oven cooks.
Set Temperature, IR Element (IRSP and IRSI)
IRSP is the set temperature of the IR element during a given cook cycle. Settings are determined on a
per-recipe basis. IRSI is the set temperature of the IR element during the READY STATE (or “idle”). IRSI
setting can be adjusted in the
TEST MODE (page 16).
Actual Temperature, Cook Cavity (TCC)
The actual temperature registered by the cook cavity thermocouple.
Actual Temperature, IR Element (TIR)
The actual temperature registered by the IR element.
Edit Mode
Enables the user to change recipe and CCSP/IRSP temperature settings.
Warm-Up
The mode in which the oven warms itself to the set temperature.
Soak
The mode in which the oven temperature has reached the CCSP, and remains in warmup for an addi-
tional 8 minutes to allow cook cavity surfaces to warm. The oven will proceed to soak only if warm-up
was initiated when TCC < (CCSP - 126
º
F) or TCC < (CCSP - 66
º
C).
Cook Cycle
A period of operation as defined by a recipe.
Test Mode
A special diagnostic mode that enables the service technician to turn on and off all oven systems
independent of one another, check oven statistics, and set the IRSI.
