I am a software developer who doesn't know much at all about HVAC, and only recently have I started to pay attention to what's installed in my house. I guess there are HVAC guys who only recently started to pay attention to what's installed on their computers, so maybe I shouldn't feel too bad about that :cheers:
BTW, I tried to ask a question in the residential forum and attach some pictures, but the site won't show me the pictures I uploaded when I click on the links, saying that I don't have permission to do so.
Happy to make your acquaintance.
Welcome to the site, it may have been because you did not introduce yourself first...if it still won't let you then contact the site.
