Parameter 
AWS Rst 
A bit will trigger the following action in the fan when it is set: 
Reset    : Software reset (includes "Reset error" and "Adopt parameters") 
     The software is launched at the start of booting 
Error    : Errors are reset 
Parameter  : All parameters are copied from the EEPROM into the RAM 
   This bit must be set to make revised parameters valid 
Reset AWS  : User software reset  
 (includes "Reset error" and "Adopt parameters") 
 The software is reinitialised 
After the action has been executed, the bit will automatically be reset by the fan. 
When reset (bit 3), the program will be relaunched at the start of booting. Commands from the master will then 
be neither responded to nor executed for a few seconds. 
Reset (bit 3) is only recommended if new user software is to be loaded using a bootloader (because 
communication is interrupted). 
If only the software is to be reinitialised, user software reset (bit 0) is recommended. Then communication is 
not interrupted.
