Connect Touch Control
Connect Touch control, 5” user interface - Remote management (option) • The Energy Management Module offers extended remote control possibilities: • Set point reset: ensures reset of the cooling set-point based on a 4-20 mA signal • Demand limit: permits limitation of the maximum chiller power or current based on a 4-20 mA signal • Demand limit 1 and 2: closing of these contacts limits the maximum chiller power or current to two predefined values • User safety: this contact can be used for any customer safety loop; opening of the contact generates a specific alarm • Ice storage end: when ice storage has finished, this input permits return to the second set-point (unoccupied mode) • Time schedule override: closing of this contact cancels the time schedule effects • Out of service: this signal indicates that the chiller is completely out of service • Chiller capacity: this analogue output (0-10 V) gives an immediate indication of the chiller capacity • Alert indication: this volt-free contact indicates the necessity to carry out a maintenance operation or the presence of a minor fault.

- Energy management: • Internal time schedule clock controls chiller on/off times and operation at a second set-point • The Black Box records the alarms history to simplify and facilitate service operations. - Remote Management (Web connectivity in standard) • Units with Connect Touch control can be easily accessed from the internet, using a PC with an Ethernet connection. This makes remote control quick and easy and offers significant advantages for service operations. • The unit also communicates with other building management systems via modbus in standard or via optional communication gateways Lon, Bacnet. • The unit is equipped with an RS485 serial port that offers multiple remote control, monitoring and diagnostic possibilities. Ciat offers a vast choice of control products, specially designed to control, manage and supervise the operation of an air conditioning system. Please consult your Ciat representative for more information. - The following commands/visualisations are possible from remote connection (standard): • Condenser pumps control: a digital input allows verification of condenser water flow (the flow switch must be supplied by the installer) • Start/stop of the machine • Dual set-point management: through a dedicated contact is possible to activate a second set-point (example: unoccupied mode) • Demand limit setting: to limit the maximum chiller capacity to a predefined value • Operation visualization: indication if the unit is operating or if it's in stand-by (no cooling load) • alarm visualization.
