If the ST216 is programmed to heat the kiln at a faster rate than the kiln is
capable of then the ST216 will turn on full power then wait until the kiln tem-
perature has risen to the correct temperature before proceeding to the next
ramp or soak.
Likewise if the ST216 is programmed to cool the kiln at a faster rate than the
kiln is capable of then the ST216 will apply zero power then wait until the kiln
has cooled to the correct temperature before proceeding to the next ramp or
soak.

Heating & Cooling Ramps
Normally the ST216 will be used only for heating but it is actually capable of
controlled ramps for both heating and cooling. If for instance t1 is higher
than the soak temperature then the ST216 will perform controlled cooling
down to the soak temperature.

Key Operation
If the
►
n
key is pressed during a firing then the firing will be halted (not
paused). Pressing the
►
n
key again will cause the ST216 to restart the
firing from the beginning. The ST216 will look at the current kiln temperature
and if this is greater than t1 then the ST216 will automatically
cool
from the
current temperature to t1. This may not be what is desired so the
►
n
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 (see next section). This is a better option than using the
►
n
key. The program advance feature is however available to recover quickly
from
►
n
key operation if required.
Memory
All programs & necessary data are remembered when the ST216 is turned
off. In the event of power failure during firing the ST216 will automatically
resume firing when power is returned (this feature can be disabled: see In-
stallation Handbook).
Delayed Start
By default the delayed start time period is initialised to 00:00 for each firing.
The ST216 can however be configured to remember the delayed start time
period (see Installation Handbook).
