Hi! I am trying to convert Fujitsu (General) AC split system (DC Inverter type R410( to air/water heat pump. I have an outdoor unit without indoor unit. Do you thinks it's possible to use this code for communicating with the outdoor unit directly without the indoor unit (turn on/off etc)? Outdoor unit has following terminal connections:, by the wiring schematics they are identified as follows: (1) N ; (2) L ; (3) Serial; (4) Earth. Does this make it as some kind of 1-wire serial communication interface? Is there any kind of universal protocol for outdoor units or it's proprietary for each manufacturer?
Thanks for any kind of information in advance!
