Anyone have information on the Microzone CVV-90111-0-0-2 Controller? I have no literature for this controller and would like to at least know what terminals are for what.

The controller you are describing sounds like the Microzone II. Those terminals are clearly marked. This is an older Microzone unit. Possibly the Microzone I? It has a double terminal strip at the top and the bottom with mixed spade and screw connections.

Yes! Any help will be appreciated. Its operating on a rooftop unit with vav controls with a 25 ton system. We just changed over one of the units from a 25 ton carrier and the other a 25 ton trane. Both are now Trane. A/C and economizer only. Heat is in the vav boxes. Thanks for your assistance!
