AQUASMART EVOLUTION FEATURING THE NEW SYSTEM MANAGER FOR THE AQUASMART SYSTEM Controls Aquasmart Description Features • • • Aquasmart Evolution is a complete heating, ventilating and air conditioning (HVAC) system, ideal for residential and light commercial office buildings, hotels and hospitals. It offers perfect comfort for the building occupants.
Aquasmart System design layout and configuration guide Energy savings • • • • The System Manager is connected to the system components via a communication bus, and allows control of all system and individual terminal operating parameters. System configuration is simple through easily accessible menus. Unit grouping is managed by the network and requires no specific wiring. This means the system can be easily reconfigured to suit later modifications to the occupied area.
Aquasmart New System Manager System selection • • • • • • • • • The New System Manager is a human interface that allows users to manage the Aquasmart system components and features major improvements over the previous System Manager. An intuitive colour touch screen interface facilitates access to the system parameters.
Aquasmart New features for 2011 • • • • • The Touch Pilot System Manager can now manage up to eight fresh air handling units as part of the system. The air treatment units (39SQ) supplied by Carrier are equipped with CCN controllers, they are fully integrated into the system and managed by the Aquasmart System Manager. Each fresh air plant can be associated with specific terminal fan coils and/or zones for optimum management of building use with occupancy, controlling and minimising energy use.
