Hello Folks, ok, basically I'm just reading reading and reading trying to find out the answers myself but falling short after going through the manual for my Multi Plus 24/3000/70 and direct internet sourcing. Please see the two attachments, one is almost how my setup is with the addition of an Orion 24/12-70 and the other is from my gathered Electrodacus info file showing the EXTIO info. The EXTIO info is talking about which types of aux function is required by the VE equipement, basically in my layperson's idea of thinking : volt free switching or a voltage given out by BMS to switch/control the device. I understand all that is being said but I cannot find any reference in the manual indicating the remote switching or controlling contact spec. I hope I've made sense here and welcome the usual positive response from you guy's. TIA
