Hey Pierre,
 
Thanks for reachingg out to us and welcome to our community. I would be happy to take a look at your wiring setup. 
 
Can you please provide a photo of your HVAC's wiring? That way, I can read which wire is going where. 
 
I look forward to your response and am hopeful we can decode the wires. 🙂
