Main part
The execution of the main part begins when a power-on conrmation
signal from the Computing Unit is received. This signal informs freecooler
about the motherboard complex start and the launch of the entire system.
When switching to this operating mode, all connected fans and pumps
go into operating mode and are set to 100%. The freecooler controls
the working order of internal components and acceptable operating
modes, the display shows information according to the User’s choice.
For the sake of convenience, the displayed information can be scrolled
using the illuminated buttons of the cooling module.
