AQUACIATPOWER TM LD Water chillers ■ Connect Touch remote management Connect Touch is equipped as standard with an RS485 port and an ETHERNET (IP) connection,offering a range of options for remote management, monitoring and diagnostics. Using the integrated Webserver, a simple internet connection uses the unit's IP address to access the Connect Touch interface on the PC, facilitating everyday management tasks and maintenance operations. A range of communication protocols are available: MODBUS/ JBUS RTU (RS485) or TC/IP as standard,LONWORKS – BACNET IP as an option, enabling most CMS/BMS to be integrated Several contacts are available as standard,enabling the machine to be controlled remotely by wired link: - Automatic operation control: when this contact is open, the machine stops - Setpoint 1/setpoint 2 selector: when this contact is closed, a second cooling setpoint is activated (energy storage or unoccupied mode, for example) - Power limitation: closing the contact concerned allows the power or refrigerating consumption of the machine to be limited by stopping one or more compressors (this limit can be set with a parameter) Web server IP address - Fault reporting: this contact indicates the presence of a major fault which has caused one or both refrigerant circuits to stop - Operational status reporting: indicates that the unit is in production Remote management via web server mode Connection to RJ port - Activation control for partial energy recovery using the Connection via IP address desuperheater All the HMI functionalities - Switch control for the customer pump, external to the machine available on the PC (on/off). Simplified remote monitoring - Pump control: 0/10V signal to control external variable speed pump Contacts available as an option: - Setpoint adjustable via 4-20 mA signal: this input is used to adjust the setpoint in COOLING mode E-mail - Power limitation adjustable by 4-20 mA signal alerts - Second power limitation level - Power indication: analogue output (0-10 V) providing an indication of the unit's load rate - User fault reporting: enables integration of a fault in the water loop - General fault reporting: this contact indicates that the unit has stopped completely - Alert reporting: this contact indicates the presence of a minor fault which did not cause the circuit in question to stop - End of storage signal: enables return to the second setpoint at the end of the storage cycle - Schedule override: closing this contact cancels the time schedule - Desuperheater activation control - Desuperheater pump On/Off control 420 420 CATALOGUE 2021
