AIR-COOLED LIQUID CHILLERS 30XA 252-1702 CONTROLS AIR TREATMENT ■■ New innovative smart control features: -- An intuitive and user-friendly, coloured, 5'' interface (7" optional) -- Direct access to the unit's technical drawings and the main service documents -- Screen-shots with coincisive and clear information in local languages -- Complete menu, customised for different users (end user, service personnel and Carrier-factory technicians) -- Easy access to the controller box with inclined touch screen mounting to ensure legibility under any lighting conditions -- Safe operation and unit setting: password protection ensures that unauthorised people cannot modify any advanced parameters -- Simple and "smart" intelligence uses data collection from the constant monitoring of all machine parameters to optimise unit operation. ■■ Energy management: -- Internal time schedule clock controls chiller on/off times and operation at a second set-point -- The DCT (Data Collection Tool) records the alarms history to simplify and facilitate service operations. ■■ Units with Touch Pilot control can be easily accessed from the internet, using a PC with an Ethernet connection. This makes remote control quick and easy and offers significant advantages for service operations. ■■ AquaForce is equipped with an RS485 serial port that offers multiple remote control, monitoring and diagnostic possibilities. When networked with other Carrier equipment through the CCN (Carrier Comfort Network - proprietary protocol), all components form a HVAC system fully-integrated and balanced through one of the Carrier's network system products, like the Chiller System Manager or the Plant System Manager (optional). ■■ AquaForce also communicates with other building management systems via optional communication gateways. ■■ The following commands/visualisations are possible from remote connection: -- Start/stop of the machine -- Dual set-point management: through a dedicated contact is possible to activate a second set-point (example: unoccupied mode) -- Demand limit setting: to limit the maximum chiller capacity to a predefined value -- Water pump control: these outputs control the contactors of one/two evaporator water pums -- Water pumps on reversal (only with options 116C/116G): these contacts are used to detect a water pump operation fault and automatically change over to the other pump -- Operation visualisation: indication if the unit is operating or if it's in stand-by (no cooling load) - alarm visualisation.
