Control unit CMC III PU (see fig. 11, item 5)
The Liquid Cooling Package consists of a fuse box, a
superordinate control unit (CMC III PU), a water mod-
ule, a heat exchanger, and the fan modules. In its sup-
plied state, the following fan modules are built into the
devices:

The fan modules and the water module contain their
own electronic controls (1 x RLCP fan and 1 x RLCP
water), which are connected to the CMC III PU via a
CAN bus. The fan modules are switched on sequen-
tially from one to six (or one to four with
LCP Inline flush) via a startup current limitation once
connected to the mains voltage.
