8.2
In case of prolonged fan inactivity, this self-maintenance function is activated. To activate the antilock, the unit must
be switched on.
If the fans remain OFF for duration PL02 since the last activation, all the system fans are activated at the same time for
duration PL03. For the duration of the starting up process, the fans rotate at the speed indicated by parameter PL01.
Antilock rotation is also activated by the antifreeze function in the event of fan inactivity if the outdoor temperature
remains below temperature threshold parameter PL04 for a duration equal to parameter PL05.
To deactivate the function, simply set parameter PL01 to 0%.
