The connection cable, used in the PROAIR MULTI-ZONE systems, is an 8-wire telephone type without wired connector in a 100 m coil to meet the different installation situations.
The cables are necessary for the cascading connection between the control unit and the dampers (or nozzles), motorised by-pass and relay modules.
Attention! Use only Tecnosystemi cables - do not use cables other than those indicated in order not to compromise the correct functioning of the system.
