4 head mini split heat pump system help
I recently intalled a 4 head mini split heat pump system. Inverter flex in the brand. The issue I am having is that I can't get one of the units to blow heat. When I run the three others they heat just fine. When I try and run that one it puts on the outdoor unit but when the indoor unit blower kicks on it just blows air. No heat. I have ran they all together and Individually. I have tried tech support but can't get through when I am on site and they are only available on normal business hours.
