My new air conditioner is an LG inverter. Yet to be installed. I'm wondering about the cables. I'm replacing an older sanyo system that had an 8 wire cable between the indoor unit and the outdoor unit. This one just has a 3 pin plug on the indoor unit and 3 or 4 hardwire connections on the outdoor unit. So if thats just power, how do the units "communicate" with each other.

Fujitsu.
Use to put a Signal into the 240v lines between the two units to communicate.
It kind of looks like a spike when looking at it with an oscilloscope.
Tricky stuff.
It might be doing that.

Hey I worked this out in the end. The manual says "connect the wires between the 2 units" basically. I reckon the lack of explanation is to prevent DIY. I had to run a 4 wire cable between the units. +,-, gnd and the 4th communication i presume. There was a small drawing of it etched in the plastic.
