AIR-COOLED LIQUID CHILLERS 30XAV 500-1150
Touch Pilot control
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.
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 with Greenspeed® Intelligence 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). The 30XAV 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 pumps. - Water pumps on reversal (only with options 116S/116U): 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 is in stand-by (no cooling load) - Alarm visualisation.

Notes: Evaporator ΔT = 5K. These ranges are given by way of indication. Verify the operating range from the Carrier electronic catalogue.
Entering air temperature, °C
Legend Operating range of standard unit 30XAV Below 0 °C air temperature the unit must either be equipped with the evaporator frost protection option 41A, or the water loop must be protected against frost by using a frost protection solution (by the installer). For start-ups with air temperature below -5 °C, the machine must be equipped with option 41A.
