. he apparatus goes into the hold

mode and regulates further to the actual value. If necessary,
the apparatus is partially ventilated. 

[ESC]

 puts back into

the 

RUN 

mode with the original set point. 

[OK]

 puts back

into the 

RUN

 mode with the new set point. Use 

[AUTO]

to put distillation back into the automatic mode.

Change into the manual mode 

ð

 

[MAN]

. Now, distillation

can be continued manually (for example, if the distillation is
too slow). You can change back to the automatic mode
at any time.

Now, the controller is ready and you can use 

[RUN]
