23. DEVICE ERROR MESSAGES
The control board installed inside the heat recovery unit has multi-color LED. In the event of a fault,
the corresponding fault code will be displayed with different color
fl
ashes. With the help of the
colors assumed by the signaling LED it is possible to search for the meaning of the relative error
message. Recognizing the sequence reproduced by the LED is useful for technical assistance in
recognizing the type of fault in progress. Below is a summary table of possible errors.
