°F/°C Temperature Conversion Formulas
Below are formulas for converting temperture between
°F and °C. Converting a firing rate requires a different for-
mula than converting a firing temperature:
Firing to a Temperature
(i.e. “Fire to 1600°F.” 1600°F = 871°C)
(°C x 1.8) +32 = °F
(°F - 32) ÷ 1.8 = °C
Firing Rate or Temperature Change
(i.e. “Fire at 200°F per hour” or “Fire 200°F hotter.” 200°F =
111°C)
°C x 1.8 = °F
°F ÷ 1.8 = °C
TCOS / Thermocouple Offset
Calibrate the Thermocouple(s)
The thermocouple is the rod protruding into the firing
chamber. It measures temperature. K-Type thermocouples
can “drift” as they age, causing a gradual shift in tempera-
ture readings. Thermocouple Offset calibrates the control-
ler to compensate for drift.
Note:
The thermocouple must protrude into the
firing chamber the correct distance: about ¾” for
¼” wide thermocouples, ½” - 5/8” for 1/8” wide
thermocouples.
Setting Thermocouple Offset
You can enter a temperature change up to 45°F/25°C
higher or lower than the zero factory setting.

AOP1, AOP2 / Auxiliary Outputs
Select Vent Fan or Alarm for the Auxiliary Outputs
The
[AOP1]
and
[AOP2]
(Auxiliary Outputs) are for re-
ceptacles (called sockets in England) mounted on the kiln
switch box. The outlets can power a kiln vent or an external
alarm, such as a bell. (An AOP outlet is optional and might
not be included on your kiln.)
The choices in the
[AOP1]
and
[AOP2]
options:
I
[VFAN]
Kiln Vent or Gas Outlet:
This option adds a
display prompt for fan (
[ FN]
) to each segment during
Ramp-Hold programming (page 15).
I
[CPT]
When the kiln fires to completion, and
[CPTL]
appears in the display, the controller will turn on power
to the AOP outlet. Plug a bell or other alarm into the
AOP outlet to notify you that the firing is done.
I
[ALRM]
Alarm:
This choice sends power to the AOP
receptacle whenever the alarm sounds. (See Tempera-
22
Cone-Fire / Ramp-Hold
Do not leave your kiln unattended during operation.
