DYNACIATTM LG Water chillers Heat pump Description of the main components ■ 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 (Certified BTL) as an option, enabling most CMS/ BMS to be integrated. Web server IP address Severalcontacts are available as standard, enabling the machine to be controlled remotely by wired link: Remote management via web server - Automatic operation control:when this contact is open, Connection to RJ port the machine stops Connection via IP address - Heating/cooling operating mode selection All the HMI functionalities available on - Setpoint 1/setpoint 2 selector: when this contact is closed, the PC a second cooling setpoint is activated (energy storage or Simplified remote monitoring 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) - Fault reporting:this contact indicates the presence of a major fault which has caused one or both refrigerating circuits to stop E-mail - Operationalstatus reporting indicates that the unit is in alerts production mode. ■ Maintenance Connect Touch has two maintenance reminder functions - The scheduled maintenance reminder: when activated, as standard,making users aware of the need to regularly this function enables the period between two maintenance perform maintenance operations and to guarantee the service inspections to be set.
