HVACPro is not very Windows 7 friendly; It's not supported. That being said it runs on many Windows 7 machines (including JCI tech laptops) but I've also seen plenty of machines it will not run on. Ensure you're running it in Windows XP mode and cross your fingers! Also make sure you're running version 8.08b.

I can echo the Windows 7 and HVACPro sometimes don't play together. Windows XP Professional seemed to work really well although. If you could look at the front end you could determine which controllers are offfline and work from there!!!!

Wasn't able to connect with hvac pro. We did find that you cannot use the same 24 vac from the new unit to power the unt100. The new unit is a Mcquay Infinity. We had the same issue with Novar ucm's about 3 yrs ago. They have "noisy voltage" that doesn't work well with third party devices. We isolated the 24 vac and they came right up communicating!

Forgot about those pesky 24V Isolation Transformers that used to be needed. Glad you got it up and running.

Thanks desert guy that was a pain. After that the "old" unt100 wouldn't work the outputs we had to switch the hot/common and there working great now. Wouldn't mind not seeing that building again.
