Tips on troubleshooting
Standard practice for suspected malfunction should be to first of all check all settings in the
menus
Par
and
Men
as well as the terminals.
Malfunction but "realistic" temperature values:
 Check the program number.
 Check the switch-on and switch-off thresholds as well as the temperature differential
settings. Have the thermostat and differential thresholds already (or not yet) been
reached?
 Have settings been changed in the submenus (
Men
)?
 Is it possible to switch the output on and off in manual mode? - If endurance runs and
standstills at the output result in appropriate reactions the device is definitely in order.
 Are all sensors connected to the correct terminals? - Heat the sensors using a lighter and
check the display.
Wrongly displayed temperature(s):

If a value such as -999 is displayed when a sensor short-circuits or 999 if there is a sen-
sor interruption, the cause may not be a material or terminal error. Are the correct sensor
types (KTY or PT1000) selected in menu
Men
under
SENSOR
?
The factory setting sets all inputs to PT (1000).
 The sensor can also be checked without a measuring device simply by changing the
sensor that is probably defective with one that works at the strip terminal and checking
the temperature display. The resistance measured with an ohmmeter should have
following value according to temperature:
Temp.
[°C] 0 10 20 25 30 40 50 60 70 80 90 100
R (Pt1000)
[ Ω ] 1000 1039 1078 1097 1117 1155 1194 1232 1271 1309 1347 1385
R (KTY)
[ Ω ] 1630 1772 1922 2000 2080 2245 2417 2597 2785 2980 3182 3392
The factory setting of the parameter and menu functions can be restored at any time
by pressing the lower key (Entry) during plugging in. WELOAD appears in the display
for three seconds to indicate loading of the factory setting.
If in spite of connection to the supply voltage the device is not working the 3.15A
fast-acting fuse which protects the controls and the output should be checked or
replaced.
Since the programs are continually being revised and improved it is possible that there are
differences in the sensor, pump and program numbering compared with older documentation.
Only the accompanying operating manual is valid for the device supplied (identical serial
number). The program version of the manual must categorically correspond with that of the
device.
Should in spite of inspecting and checking in accordance with the above-mentioned tips a
malfunction of the controller be apparent please get in contact with your dealer or directly
with the manufacturer. The cause of the malfunction can only be found however when in
addition to the description of the malfunction
a fully completed table of the settings
and if
possible a hydraulics diagram for the system are provided.
