AQUACIATTMLD ILD Water chillers Heat pump ■ 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. Several contacts are available as standard, enabling the Web server IP address machine to be controlled remotely by wired link: -Automatic operation control: when this contact is open, the machine stops -Heating/cooling operating mode selection -Setpoint 1/setpoint 2 selector: when this contact is closed, Remote management via web a second cooling setpoint is activated (energy storage or server unoccupied mode, for example) Connection to RJ port Connection via IP address -Power limitation: closing the contact concerned allows the All the HMI functionalities power or refrigerating consumption of the machine to be available on the PC limited by stopping one or more compressors (this limit can Simplified remote monitoring be set with a parameter) -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 E-mail - production mode. alerts -Activation control for partial energy recovery using the desuperheater -Switch control for the customer pump, external to the machine (on/off). -0-10V output available for control of a variable flow pump (unit without hydraulic module) Contacts available as an option: - Setpoint adjustable via 4-20 mA signal: this input is used to adjust the setpoint in COOLING mode - On/off control for a boiler - 4-stage on/off management for additional heaters. ■ Maintenance Connect Touch has two maintenance reminder functions as - the scheduled maintenance reminder: when activated, this standard, making users aware of the need to regularly perform function enables the period between two maintenance maintenance operations and to guarantee the service life and inspections to be set. This period may be set by the operator performance of the unit. These two functions can be activated in either days, months or operating hours, depending on the independently. application. A reminder message appears on the unit's HMI screen, and - The compulsory F-GAS sealing test maintenance reminder: stays there until it is acknowledged by the maintenance when activated, this function, which is the default factory operator. The information and alert relating to these functions setting, enables the period between two sealing tests to be are available on the communication bus to be used on the CMS/ selected, according to the refrigerant charge, in compliance BMS. with the F-GAS regulations 358 358 CATALOGUE 2021
