Could someone please share how they wired an auxiliary fan with a Multiplus 12/3000? I've read a couple other posts that mention setup of the assistants, and I've set up 2 (one ON and one OFF) through the K1 relay. However, the documentation isn't very clear on what the NO/NC/COM ports are actually doing when the assistants are setup to "turn on". I understand NO = normally open, NC = normally closed, and COM is the common. I've tried wiring a couple different ways and haven't had success with the auxiliary fan turning on following the inverter fan. It is a 12v, 0.16A 120mm computer fan. I've tried wiring directly to the K1 relay port, using the NO as power supply and common as battery negative. I've also tried providing power separately via a 4-pin relay, treating the NO port like a switch+.
