Hello osmoreno,

Thank you for taking the time to let us know about your inquiry. I'd be happy to take a look at this for you.

To determine your system's configuration, could you please share with us photos of your thermostat's wiring and your HVAC system's circuit board showing how they are being installed?

I'll look forward to your response.

Regards,

Mark
