Interesting. I never had to this problem before with any units. Thanks for the demonstration sir. I'm fairly new to commercial equipment, I only been doing it for about a year and half.

Hi thanks that was ventor motor for heat

Sorry I didn't get you, but that unit does not have inverter compressors

Thanks that was terminal Y on phase monitor

@@Learnhvac. Yes, I did follow that from the diagram and then on the physical device, but I still can't determine the word or phrase you were speaking. You said "directly connected to....Y (air)". And then a few seconds later you said 3 phase supply (air). I think the captions show it as "here". Is that correct?

😂yea its here

@@Learnhvac. Ok thanks 👍

I use my cell phone for video recording so yea some time it's hard
