I have a Bonaire heating/cooling system at my house. Controller is a ct10mc04 panel (power, mode, up, down buttons). Is it possible to use a scope or logic analyser to work out what each button is doing,so I can replicate that with an arduino?
I'm not really sure where to even start with connecting it up. Do these normally run some sort of general protocol or language, or is everything usually custom proprietary, and harder to work with? Are there any online resources for this sort of stuff?
