Hi, Phil! Tell me about your VRV's properly: model of units, who made your stuff (DENV, Japan etc.), place where is your br3kjvi mounted.

hi, function box or flow selector box is type of capacity control i think! with 3 vrv connected to the function box...from the function box you have valves opening and closing as required to a common suc/disc/liquid....models are (rny8ky1r) x2.........(rxy8ky1r) x1..........(br3kjv1) x1

they come from daikin belguim and the box is mounted beside outdoors...

I've never had a whine from one -occasionally a noisy sol coil.

However have you checked the charge (a day wasted know) but it's usually this that causes these issues..

If you know anyone who understands them -hold on very tightly as few in the world do
