AIR-COOLED LIQUID CHILLERS 30XA 252-1702 Touch Pilot Control
Touch Pilot control, 5” user interface
Remote Management (Standard)
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.
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.
