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.
Numerous communication protocols are available: MODBUS/
JBUS RTU(RS485) or TC/IP as standard, LONWORKS –
BACNET IP optional, enabling integration with most CMS/BMS
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)
- heating/cooling operating mode selection
- 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
- 0-10V signal output for external variable speed pump
management
Contacts available as an option:
- setpoint adjustable via 4-20 mA signal: this input is used to
adjust the setpoint in COOLING mode
- 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 has not caused the circuit affected 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.
- drycooler management

Maintenance alert as standard
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.
