I have received the RS485 USB device today.
Anyway,
I just came to think. I have a picture of the CTS 602 controller print located inside of my Nilan Comfort 300LR.
It´s not quite the same as yours as far as I can tell. Perhaps a newer revision.
So I wondered if you could take a short look at it, and tell me if I´m correct, the interface/pins to use is located at the top left corner of the picture. And there are already 6 wires connected?
(Those wires are probably those connected to a pin interface located on the outside of the Comfort 300. This is where the CTS 602 display panel is connected. And if that is correct the modbus interface is available as well).
