perature Controller will maintain the 160
°
C setting until power is shut off or the RUN key is
pressed to stop the program. You may have noticed that this single setpoint program using the
hÏlË
hÏlË hÏlË hÏlË hÏlË option is exactly the same as the Single SetPoint Operation - Non Program Mode except
that we are in the program mode!
V.7 Reviewing and Editing An Existing Program
To review an existing program, press the PROG key. The PROGRAM LED will be illuminated.
Simply press the SET key to “scroll” through all the various steps of your program. When you are
done, press the PROG key once more to exit program review. If you find a program step that is in
error (or simply needs to be changed), advance to that step using the SET key and then use the
ARROW keys to change the step to the correct (or new) temperature value or mode if you are
altering the hÏlË/s‰Ïp hÏlË/s‰Ïp hÏlË/s‰Ïp hÏlË/s‰Ïp hÏlË/s‰Ïp option.
V.8 Running A Temperature/Time Program
To run a program, press the PROG key (if the PROGRAM LED is already illuminated, you do not
have to press the PROG key), and then press the RUN/STBY key. The PROGRAM LED and the
RUN LED will now both be illuminated.
When the RUN/STBY key is pressed, Programmable Temperature Controller will begin ramping to
that temperature. The HEAT LED will be illuminated when the Programmable Temperature Control-
ler is providing power to the Thermo Container. When the temperature has reached the set point for
that step (+/- 1
°
F or +/- 0.5
°
C), the Programmable Temperature Controller will maintain that tem-
perature for the programmed time period.
While the Programmable Temperature Controller is in the hold time interval for a given setpoint, you
can press the
SET key twice to obtain the following information:
1) The first press of the SET key will display the current setpoint temperature and the current step
number:
165.03
As shown here, we are holding in step 3 with a setpoint temperature of 165
°
C (or
°
F if that had
been selected as the temperature display units).
2) The second press of the SET key will display the hold time remaining in step 3 before the Pro-
grammable Temperature Controller begins ramping up (or down) to the temperature programmed
in step 4. The time remaining display would appear as follows:
8 ‰
The display shows that there are between 8 and 9 minutes left in the hold time period for this step.
It is important to remember that the Programmable Temperature Controller starts all program
steps at 0, and that all hold times are decremented to 0. This means, for instance, that if 15
