version of the device appear and after approx. three seconds
the measured actual value. If the "P" key is pressed briey, the
"Set" display appears and then the setpoint value is displayed
with an automatic return after 5 seconds. If the "P" key is pres-
sed for approx. 3 seconds, the parameter list "P10" is display-
ed. If the "P" key is held down for a further 3 seconds, " dC" for
degrees Celsius or " dF" for degrees Fahrenheit is displayed.
Protection against unauthorized operation
The control setpoints can basically be set without restriction,
provided they are not limited by "P13/P14". All other parame-
ters are protected by a code.
If a code is required, the display shows "C00". Use the arrow
keys "
/ " to set the required code number "C42" and
conrm with "P".
After approx. 1 minute without pressing any key, the code is
requested again.

If you hold down the arrow keys " / ", the values continue
to scroll automatically.
