3.3.3 Running a Temperature Program
NOTE: This function is available on Programmable Controllers only.
The Programmable Controller can store up to 10 user-defined time/temperature programs, which can later be run with
just a few simple commands. See Entering/Modifying a Temperature Program above for more information.
Programs may be run using either a Time- or Temperature-based priority. This priority is selected under Program in the
Preferences menu (see Setting Preferences below).
When Time is used, the program begins running when the bath temperature reaches the programmed set point for step
one. It continues running until the total programmed length of time for all steps has elapsed, regardless of whether the
set point temperatures for steps two and above have been achieved.
When Temperature is selected as the priority, the program begins running when the bath temperature reaches the
programmed set point for step one. Each subsequent step is run until the programmed set point for that step is reached,
regardless of how much time has elapsed.
Selecting a Program— To select a temperature program, rotate the Select/Set Knob until the Run Program menu
appears and then press the Select/Set Knob.
If the Program # field is highlighted as shown above, press the Select/Set Knob and then rotate the Select/Set Knob
until the number of the program you wish to run is displayed.
Press the Select/Set Knob a second time to accept the displayed program number. If the word Start is highlighted,
rotate the Select/Set Knob one click counter-clockwise to highlight the program number.
Running a Program — Once you have selected and accepted the program number, rotate the Select/Set Knob until
Start is highlighted. Press the Select/Set Knob; the program will automatically begin running. The word “Starting” will
appear at the lower left of the Run Program menu and will remain there until the bath temperature reaches the set point
programmed for step one. It will then be replaced by the word “Running.”
While a program is running, the Run Program and main operational displays will alternate on the LCD. The Run
Program display shows the current step number, the target set point for the next step, time at the current step, loop
number, program status, and total elapsed time. The main operational display shows bath temperature, set point, and
program status.
Pausing or Stopping a Program — A program that is running may be paused or stopped at any time. To do so, press the
Select/Set Knob until Starting or Running is highlighted and then press the Select/Set Knob again. Rotate the Select/
Set Knob until the desired function (Pause / Stop) is highlighted and then press the Select/Set Knob. If you do not wish
to pause or stop the program, select and enter Escape.
If the program has been paused, “Paused” will appear on the lower left of the display. If the program has been stopped,
“Start” will appear on the lower left of the display.
To resume running a program that has been paused, press the Select/Set Knob, select Resume, and then press the
Select/Set Knob a second time. The program will resume operation from the point of disruption. Select Stop if you wish
to stop the program or Escape if you want to keep the program paused.
