6Analog input. Two separate functions.14These low-current signals can be led by using just one cable.
7Digital input 115Connection box power supply max. 6 W
8Digital input 216NB! The ventilation unit has three vacant feedthroughs. If necessary, more holes can be added or all the required low-current signals can be led out of the unit with one cable and split outside the unit.
