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 - Heating/cooling mode selection - 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) - Fault reporting: this contact indicates the presence of a major fault which has caused one or both refrigerating circuits to stop - Operational status reporting indicates that the unit is in production mode. - Activation control for partial energy heat recovery unit using the desuperheater. - Switch control for the customer pump, external to the machine (on/ off). 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 - Power limitation adjustable by 4-20 mA signal - 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 refrigerating 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

Connect Touch has two maintenance reminder functions as standard, making users aware of the need to regularly perform maintenance operations and to guarantee the service life and performance of the unit. These two functions can be activated independently. A reminder message appears on the unit's HMI screen, and stays there until it is acknowledged by the maintenance operator. The information and alert relating to these functions are available on the communication bus to be used on the CMS/BMS. - The scheduled maintenance reminder: when activated, this function enables the period between two maintenance inspections to be set. This period may be set by the operator in either days, months or operating hours, depending on the application. - The compulsory F-GAS sealing test maintenance reminder: when activated, this function, which is the default factory setting, enables the period between two sealing tests to be selected, according to the refrigerant charge, in compliance with the F-GAS regulations.
