Barber Coleman CVV-90111-0-0-2 Microzone Controller

The Barber Coleman CVV-90111-0-0-2 Microzone Controller is a complete Microzone controller module in the Barber Colman/Invensys MACO family for HVAC zoning in commercial systems. It accepts 20–30 VAC input at 50/60 Hz and provides up to 10 VA of control power, making it suitable for powering dampers, sensors, and other Microzone devices within a MACO/Microzone installation. Catalog listings refer to it as 'Controller Complete Microzone,' indicating it ships as a complete module rather than a bare circuit board. The unit weighs about 4.16 lb and is described by suppliers as a Microzone controller, with manufacturer status listed as discontinued, reflecting its role as a legacy component in Barber Colman’s Microzone line. As part of the Microzone ecosystem, this controller is used within zoning networks alongside other Microzone components to coordinate multi-zone heating and cooling in commercial environments, serving as either a central controller or a distributed control element in older HVAC systems.
