If the ST535C is programmed to heat the kiln at a faster rate than the kiln is
capable of then the ST535C will turn on full power then wait until the kiln
temperature has risen to the correct temperature before proceeding to the
next ramp or soak segment.
Likewise if the ST535C is programmed to cool the kiln at a faster rate than
the kiln is capable of then the ST535C will apply zero power then wait until
the kiln has cooled to the correct temperature before proceeding to the next
ramp or soak segment.

Heating & Cooling Ramps
The ST535C is capable of controlled ramps for both heating and cooling.
The type of ramp required is determined by comparing the required soak
temperature to the soak temperature in the previous segment and is shown
on the mimic display.
► Key Operation
If the ► key is pressed during a firing then the firing will be halted (not
paused). Pressing the ► key again will cause the ST535C to restart the
firing from the beginning. The ST535C will look at the current kiln tempera-
ture and if this is greater than the required soak temperature then the
ST535C will automatically cool from current temperature to the soak temper-
ature. This may not be what is desired so the ► key should only be used
to halt the firing in an emergency.
The program can be paused or program data can be changed while the con-
troller is firing. This is a better option than using the ► key. The program
advance feature is however available to recover quickly from ► key opera-
tion if required (see “Adjusting While Firing” section).
Memory
All programs & necessary data are remembered when the ST535C is turned
off. In the event of power failure during firing the ST535C will automatically
resume firing when power is returned (this feature can be disabled: see in-
stallation section).
Delayed Start
By default the delayed start time period is initialised to 00:00 for each firing.
The ST535C can however be configured to remember the delayed start time
period (see Installation section).
