Chill Water Master Control Display

Chill Water Master Control Display | Compatible Replacement for CWMC Display | Centralized Control for Marine Chiller Systems

The Chill Water Master Control Display (MMC) is a robust and intelligent control interface designed for use with advanced marine chiller systems. This display unit is engineered to be a fully compatible replacement for the CWMC control display originally offered with select Dometic / Marine Air Systems® chillers. Whether you’re upgrading your existing setup or replacing a faulty display, the MMC offers enhanced reliability, functionality, and ease of use.

Designed as the perfect companion to the Chill Water Master Control Board (MCC), this control display acts as the central user interface for monitoring and managing your vessel’s chilled water HVAC system. When paired with the DDC control board, the system provides centralized operation of up to six chiller stages, optimizing compressor functionality, energy use, and temperature stability throughout the vessel.

Through its clear and intuitive interface, the Chill Water Master Control Display offers real-time system feedback and diagnostic capabilities. Users can easily view inlet and outlet water temperatures, monitor compressor run times, and access detailed fault codes and system alerts. This level of transparency allows for faster troubleshooting, reduced downtime, and improved long-term performance of your onboard climate system.

Built with marine-grade components, the MMC display is designed to withstand the challenging conditions of the marine environment, including humidity, vibration, and temperature fluctuations. Its rugged construction and long service life make it ideal for both recreational and commercial marine applications.
