Introduction
The 2019 controls portfolio for General’s AIRSTAGE™ VRF systems embodies a sophisticated suite of solutions designed to meet the diverse operational demands of contemporary commercial and residential environments. Engineered to complement the company’s modular and heat-pump VRF outdoor-unit platforms, the controls lineup emphasises three strategic dimensions: flexibility, efficiency, and serviceability.
Flexibility is achieved through a versatile selection of control architectures — from individual room-based wired or wireless remotes to full-scale centralised Building Management System (BMS) integration. The portfolio supports wired touch-panel interfaces, group remote controllers and a range of gateways native to BACnet®, MODBUS®, KNX® and other open-protocol frameworks.
Efficiency is embedded through intelligent features such as economy mode, capacity-reduction settings, precise refrigerant-flow control and auto change-over between cooling and heating modes. These functions help to maintain comfort while reducing peak power draw and improving seasonal performance.
Serviceability is not left behind: the 2019 controls suite offers built-in diagnostics, Web-based monitoring tools, automatic address-setting of indoor/outdoor units and readily accessible PCB-mounted LEDs for fault and status reporting. These features support rapid commissioning, ease maintenance and minimise downtime.
In sum, the 2019 controls lineup by General has been architected to support high-performance VRF systems across a spectrum of building types — delivering advanced control capability, installation flexibility and streamlined serviceability, while aligning with the company’s established performance and reliability standards.
