IN / OUT extensions
For devices with an extended range of functions (e.g. thermofin
®
adiabatic pad cooler or thermofin
®
hybrid cooler), the digital and analogue I/Os from the TCS.2 basic unit are not sufficient. They are
then expanded with external I/O modules via the CAN bus. After loading the factory settings, these
are automatically selected or deselected. Depending on requirements and the heat exchanger
system, this presetting can still be adjusted in the following menu.
