Instructions for troubleshooting:
In general, all of the settings in the menus and the terminals should be checked if there is
an error.
Malfunction, but “realistic” temperatures:
Check the program number.
Check the thresholds for on/off (min/max) and the set differential temperatures (diff). Have
the thermostat and differential thresholds been (resp. not been) reached?
Are time windows linked to outputs?
Which priority is defined?
What is changed in the sub menus?
Can the output be switched on/off in manual mode? - If endurance runs and standstill at
the output produce an appropriate reaction, the unit is definitely not broken.
Are all of the sensors connected to the right terminals? - Heat the sensor using a lighter
and check the display.
Incorrect temperature displayed:
If a value such as -999 is displayed when a sensor short-circuits or 999 if there is an inter-
ruption, the cause may not be a material or terminal error. Are the correct sensor types
(KTY or Pt1000) selected under the menu
SEn
? The factory settings have all inputs set to
P
(Pt1000).
The sensor can also be checked without a measuring device simply by changing the part
that is probably defective with one that works at the strip terminal and checking the dis-
play. The resistance measured with an ohmmeter should have the following value accord-
ing to the temperature:
Temp.

If the unit does not run when it has power, the quick-blow fuse 3.15A that protects
the control system and the output should be checked and exchanged if necessary.
The
settings of the menu functions ex works
can be
restored
at any time using the yel-
low key „
Eingabe
“ when plugging the unit in.
As the programs are constantly being revised and improved, there may be a difference in
the numbering of the sensors, pumps, and programs. Only the instruction manual provided
with the device delivered applies (identical version number). The version number of the man-
ual must correspond to the one for the device.
If the control system malfunctions despite these checks as described above, please con-
tact your retailer or the manufacturer directly. The cause of the error can only be determined
if the
table of settings has been completely filled
in along with a description of the error. If
possible, also include a hydraulic diagram of the system.
