high 

Are the fins clean and have the oper-
ating ranges been maintained? 

Clean fins, place unit in the 
shade  

E05/E25  Frost protection activated 

Is the supply temperature 4°C or 
lower? 

Increase discharge temperature 

E06/E07/
E26/E27/
E40 

Sensors defective ST1 to ST6 

It is the alarm activated when the 
sensor is replaced? 

Replace defective sensors 

E41 

Flow switch (differential pres-
sure monitor) activated 

Are the following values OK: 

Volume of current (too large/small) 

No air in the monitoring pipes 

Circulation pump 

Does the monitor switch on and off 

Stop mechanisms are open 

Water pressure too high/low 

Have checked by authorised 
company 

E42 

Hardware defective 

Does the regulation function 
smoothly? 

Have regulation replaced by 
authorised company 

 

Compressor contact defective 

Is the COMP LED lit up and is there 
current on the contact? 

Have the contact or compressor 
replaced by an authorised com-
pany 

The unit is 
either not 
cooling at 
all or only 
a little bit 

 

Heating capacity was in-
creased 

Has there been a structural change?  Maintain safety zones 

 

Supply temperature too high 

Is the supply temperature approx. 
5 ... 10 °C? 

Reduce discharge temperature 

 

Air in the system 

Have automatic ventilators been 
mounted on the highest possible po-
sition? 

Ventilate manually or integrate 
ventilators 

 

Liquefaction temperature too 
hot 

Are the fins clean and have the oper-
ating ranges been maintained? 

Clean fins, place unit in the 
shade, maintain operating ranges 

 

Incorrect parameter settings 

Check settings 

Change settings 

 

Sporadic operation because 
cooling requirements are too 
low 

Has the system been designed for 
smaller measurements? 

Increase the quantity of water by 
installing a storage module 

Water 
leaks out 
of the unit 

 

Leaks in pipes or defective in-
sulation 

Are there leaks and have all lines 

been insulated? 

Seal and insulate 

 

Incorrect electrical rotational 
direction 

Did the phase-sequence relay switch 
through? 

Change the rotational direction
