ELEC / Electronics Temperature
Check the Circuit Board Temperature
High temperatures in the switch box can damage the
controller circuit board, which is rated for 176°F / 80°C
maximum operating temperature. To lower board temper-
ature, use a fan to blow air across the kiln switch box into the
louvers. (But do not blow air into the kiln’s peepholes.)
When firing several kilns, position them at least three feet
apart to allow adequate air circulation.

CAUTION:
Do not operate the kiln if the ELEC
display is above 158°F / 70°C.
LOCK / Program Lock
Tamper-Proof Individual Programs
By default, Program Lock is inactive. When it has been
activated, a stored Cone-Fire or Ramp-Hold program can-
not be altered or removed from memory unless you enter a
passcode. Use Program Lock for repeat firings that you
don’t want to inadvertently change.
The pre-installed passcode is the number
3
. You can
change the passcode to any number combination of one to
four digits.
If you forget your passcode, you can reset the controller
back to the factory settings using the
[RST]
option, next
page. The passcode will then go back to the number 3.
Note:
Program Lock does not save a Delay setting.
While a program is locked, you can enter a new
Delay.

How to Unlock and Edit a Program
You have locked a program and would like to edit it. Go
into programming (see pages 11 and 15). The first prompt
you will see is
[UNLO]

ENTER
and edit the program. (If you
don’t enter the passcode, you will not be able to edit the
program, but you can still fire the kiln with it.)
Note:
If your kiln is used in a classroom, you may
want to lock only the programs that you don’t want
students to change.
Note:
Even though you cannot edit a locked pro-
gram, you can still see the settings in Program
Review.
Keep the kiln lid or door closed when the kiln is not in use.
