06T screw compressor Remote management (standard) COOLING AquaForce is equipped with an RS485 serial port that offers multiple remote control, monitoring and diagnostic possibilities. Carrier offers a vast choice of control products, specially designed to control, manage and supervise the operation of an air conditioning system. Please consult your Carrier representative for more information. AquaForce also communicates with other building management systems via optional communication gateways. A connection terminal allows remote control of the AquaForce by wired cable: -- Start/stop: opening of this contact will shut down the unit -- Dual set-point: closing of this contact activates a second set-point (example: unoccupied mode) -- Demand limit: closing of this contact limits the maximum chiller capacity to a predefined value -- Heat reclaim (option): closing of this contact allows heat reclaim mode operation -- Water pump 1 and 2 control (not available for hydronic module option 116): these outputs control the contactors of one or two evaporator water pumps -- Operation indication: this volt-free contact indicates that the chiller is operating (cooling load) or that it is ready to operate (no cooling load) -- Alert indication: this volt-free contact indicates the necessity to carry out a maintenance operation or the presence of a minor fault -- Alarm indication: this volt-free contact indicates the presence of a major fault that has led to the shut-down of one or several refrigerant circuits The Carrier 06T screw compressors benefit from Carrier’s long experience in the development of twin-rotor screw ­compressors. The compressor is equipped with bearings with oversized rollers, oil pressure lubricated for reliable and durable operation, even at maximum load.A variable control valve controlled by the oil pressure permits infinitely variable cooling capacity. This system allows optimal adjustment of the compressor cooling capacity and ensures exceptionally high stability of the chilled water leaving temperature. Among the other advantages: if a fault occurs e.g. if the condenser is fouled or at very high outside temperature, the compressor does not switch off, but continues operation with a reduced capacity (unloaded mode). The compressor is equipped with a separate oil separator that minimises the amount of oil in circulation in the refrigerant circuit and with its integrated silencer considerably reduces discharge gas pulsations for much quieter operation. Controls Touch Pilot Control ■■ 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 166 -- The DCT (Data Collection Tool) records the alarms history to simplify and facilitate service operations.
