OPERATION

2.1

Element Duty Cycles

A new PID algorithm controls the way in which the elements cycle on
and off during each cooking mode duty cycle. Every minute, the oven
temperature is compared to the set point and a recalculation occurs,
which results in varied element cycle times rather than the standard
fixed 60-second cycle.
During preheating, however, a 2-point control is still used and there is
a defined element on-time. The tables below reflect the duration and
start point by preheat mode, for cavity types A, C, and D.
Technicians should have ample time to troubleshoot element
problems during the ~10-minute preheat period.
Service Manual for Thermador Professional Series Built-in Wall Ovens
It is important to note that during regulation (regular cooking period
that follows preheat), different elements may be used and element
duty cycles will vary.

Sequence of Events

Figures 2-8 that follow reflect the sequence of events that occurs
during preheat for the various cooking modes.
