is a mode of programming that allows you to write your own firing program. When you are
entering your program you will notice data already stored. Simply write over this information. If you mis-enter data
you may either press zeros to clear the data and re-enter it or press STOP to start from the beginning.

You have the option of storing up to six firing programs. You may recall these programs at any time for future use.
We recommend that you write down which number you have assigned each program so that you do not overwrite
existing programs you have stored.

(segs)
This step is prompting you to input the total number of segments you wish to use in your program. Each segment
consists of a heating or cooling rate, a target temperature, and a hold time at that target temperature if one
is desired. You may program up to eight segments. Two programs may be connected to achieve 16 segment
programs. See instructions on page 20.

This step is prompting you to input a Temperature Rate. The display will show RA along with the current segment
number you are programming alternately with the previous data entered. You may enter any rate between 1 ºF/hr
(1 ºC/hr) to 9999 ºF/hr (9999 ºC/hr). This can be a cooling rate or a heating rate. The controller distinguishes
between the two by checking to see if the temperature entered in the next segment is hotter or cooler than the
previous segment.
Just because you enter a rate does not mean the kiln is capable of achieving that rate. Things such as element
age, load density, and temperature range will all affect the kilns ability to heat. Conversely, the kiln’s insulation
will influence its ability to cool. A rate must be entered for each segment.

(ºc#)
This prompt is asking you to enter a temperature to go to. When it gets to that temperature it will either hold at
that temperature or switch to a new rate and aim for a new temperature. If you are programming in Celsius it will
read ºC instead of ºF. The controller will allow you to program temperatures between 32 ºF (0 ºC) and 2400 ºF
(1315 ºC). A temperature should not be entered which exceeds the kilns temperature rating.

(HOLd)
A HOLD time is generally entered to allow the kiln time to balance out and all of the pieces in the kiln to reach the
input temperature before the kiln moves to the next segment. You may enter hold times of 00.00 to 99.99.
A Hold at peak temperature can be used for this reason or to gain additional heatwork to fine tune cone bends
or to fire in-between cones. Remember that everything to the left of the decimal point on the display is Hours and
everything to the right is Minutes. Excessive Hold times may cause over-fires.

Continue to enter a rate, a temperature and a hold time for all the segments. When the last segment has been
entered the display will prompt you to enter an Alarm temperature. The default is 9999 for no alarm. Input an
Alarm temperature and Press ENTER. The display will briefly flash CPL for “complete” and then return to Idle
Mode. The program is now loaded.

Before starting the program it is always a good idea to press REVIEW and make sure the data was entered
correctly. If you find an error simply press RAMP/HOLD and continue to Press ENTER until you find the error and
are able to correct it. If there is a Delay entered, when you press start the kiln will begin counting down from the
input time. Remember to turn on your vent (or prop your lid) before pressing START
