Morning - I have a Balmar alternator, Arco Zeuss regulator, Victron Smart BMS 500. I have the Arco as a Victron follower, however Arco has recommended that I use the ATC as well - kind of fail safe/back up to the can.bus messages.
Question - from the wiring diagrams I have seen, it looks like the installation should be Aux+ to ATC pin 3, ATC pin 4 to Relay pin 8 (NO), Relay pin 9 (NC) houses the Arco ATC wire. Relay pin 7/Com is not used.
Is the above correct?
