Programming Controller
The multi-programmable controller in these units provides
up to 4 separate programs of 8 ramps and 8 dwells each.
This controller also allows you to link programs together,
which allows you to achieve 64 total segments (4 pro-
grams X 16 segments). These functions are controlled by
the controller’s first two programming parameters, “Pnr”
and “Cnt.”
A maximum of 8 ramp and 8 dwell segment combinations
are available per program, thus enabling eight different
set point levels to be achieved. Each ramp is pro-
grammed by specifying the program level (PL) and the
required ramp rate (PR). The programmer then automati-
cally calculates the time that is required to attain the pro-
gram level (PL) based on desired ramp rate (PR). Dwell
segments (soak) then can be attached to each program
level (PL) to hold that temperature for a specified time.
To run a program, first determine your ramp rate, dwell
times, program levels. It is helpful to graph your program
out for ease of loading program into controller.
To Select Program Number
Push scroll button until “Pnr 1” is displayed. Push the up
or down button to select a program number from 1 to 4.
Program Entry
To Link Programs Together
Push scroll button until “Cnt n” is displayed. Press and re-
lease the up and down buttons to switch between “Cnt y”
(continue yes) and “Cnt n” (continue no). The effect of
selecting “Cnt y” is to continue the program to the next
program number. For example, if in program #3 you se-
lect “Cnt y,” when program #3 is complete, program #4
will run automatically. Setting “Cnt y” in program #4 will
initiate the start of program #1 upon the completion of
program #4. Each program will complete the selected
number of loops before continuing (see Loop Count). If
you do not want to link programs, set Cnt to “Cnt n” (con-
tinue no).

Note
Once the desired parameter has been
selected, depressing either the raise or
lower button will cause the parameter
to be replaced with the new value. At
this point, the “top dot” of the least sig-
nificant digit of the secondary display
will flash on and off. Any further use of
the UP or DOWN buttons will change
the parameter value. In all cases, the
value shown on the display is the cur-
rent working value of that parameter.
