If the ST215C is programmed to heat the kiln at a faster rate than the kiln is capable of
then the ST215C 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 ST215C is programmed to cool the kiln at a faster rate than the kiln is
capable of then the ST215C 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 ST215C 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 ST215C to restart the firing from the begin-
ning. The ST215C will look at the current kiln temperature and if this is greater than
the required soak temperature then the ST215C will automatically
cool
from current
temperature to the soak temperature. 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 controller is
firing (see next section). This is a better option than using the ► key. The program
advance feature is however available to recover quickly from ► key operation if
required.
Memory
All programs & necessary data are remembered when the ST215C is turned off. In
the event of power failure during firing the ST215C will automatically resume firing
when power is returned (this feature can be disabled: see Installation section).
Delayed Start
By default the delayed start time period is initialised to 00:00 for each firing. The
ST215C can however be configured to remember the delayed start time period (see
Installation section).
