all of the variable frequency drives I've seen have a 3 phase output, how do you use single phase equipment with them?
I use the merc 3 and 4 and i love em both but prolly like the 4 better.they do change fan speed based on room temps and setpoints.they can go from 25% speed and ramp up to 100% if needed.
I want to run 2 fans; a hood exhaust and a intake with air filter. It would be nice to use 1 controller connected to a Cap temp control. But my guess is I'll need two controllers and two speed controllers - right?
PHRESH Hyperfan with included, custom speed controller = The Bomb! Very quiet as well. I have several (as well as their filters which are smaller, lighter, and work much better than any of the other cans I've used). I will only use Phresh for the foreseeable future.Anyone have any experience with the phresh fans that come with a controller?
