Description

Aqua-Air Sapphire Display (Without Vimar Bezel) 

The Aqua-Air Sapphire Display (TWS model) is a high-performance, user-friendly thermostat display designed for marine direct expansion (D/X) air conditioning systems. Engineered with both function and retrofit versatility in mind, this advanced thermostat seamlessly controls a full range of components including the compressor, reversing valve, seawater pump, and fan motors—ensuring optimal operation of your self-contained or split marine HVAC unit.

Specifically built for compatibility with Aqua-Air’s Sapphire Series TSV and TWS thermostats, this display provides a modern and intuitive interface for precise climate control. The TWS model, offered without the Vimar® bezel, is designed as a direct retrofit for the older Aqua-Air TW-2000 digital thermostat, making it ideal for upgrading legacy systems without the need for major modifications.

Though the TSV and TWS models operate identically, the TWS version retains the same dimensions as the older TW-2000 display, allowing a clean and easy installation for retrofits. This makes it an excellent solution for boat owners or service technicians looking to replace outdated controls while maintaining a consistent look and fit within existing cutouts or wall spaces.

Functionally, the Sapphire Display offers intuitive access to a range of control options for efficient onboard temperature regulation. It is capable of managing multi-speed fans, compressor cycling, and system diagnostics with precision and reliability. The display’s straightforward button layout and clear digital readout make it easy to adjust temperature settings and modes, even in low-light environments.

Built with durability and performance in mind, the Sapphire Display is engineered to withstand the marine environment, including exposure to humidity, salt air, and vibration. Its robust design ensures long-lasting operation in both recreational and commercial vessels.
