Operation and maintenance instructions  

- Conditions: 
-  Causes:  
 • 

The setpoint cannot be fulfilled because the upper or lower limit of the fan’s working zone has been reached 

- Effects:

- Conditions: 
- Causes:
 • Crucial data from the circuit board has been lost
- Effects:

- Solutions:
 • Try a TOTAL RESET of the data using the advanced setup. If still not resolved, order a new circuit board.
