The Carrier 40VMD Multiport Distribution Controller is designed to support flexible VRF heat recovery system configurations by allowing connection of 6, 8, 10, or 16 indoor units from a single controller. It simplifies system design with quick‑connect control wiring, eliminates the need for port addressing, and allows the use of sub‑controllers to expand system capacity. Built to commercial standards, the 40VMD is compatible with Carrier VRF heat recovery outdoor units and is engineered for reliable performance and streamlined installation in complex VRF applications.
Engineered to meet NEC wiring standards and ETL construction requirements, the unit is designed for dependable operation in demanding applications. A DC fan motor, finned tube heat exchanger, and compatibility with R‑410A refrigerant support consistent, long‑term performance.
Installation is streamlined with control quick connects on all indoor units and a factory‑supplied IR receiver. All indoor unit settings can be configured through the remote controller, helping reduce commissioning time and installation complexity.
