CIAT Vectic


The Vectic control is an electronic module with microprocessor designed for the control and supervision of air-air units (especially rooftop models).

  • Description:
    • This control consist of a control board, sensors, a VecticGD graphic terminal, and a TCO user terminal (optional).This system uses a RS485 field-bus to manage additional components such as: pCOe expansion modules, SMALL board, plug-fans, probes of temperature or relative humidity of the ambient air, leak detectors, energy meters, etc.A BMS card (optional) allows the control board to be connected to a centralised technical management system with the following communication protocols: Carel, Modbus, LonWorks®, BACnetTM MSTP, Konnex, Modbus TCP/IP, BACnetTM Ethernet, TCP/IP, SNMP V1-2-3, FTP and HTTP.

      It also manages a local connection between units through a pLAN network (μPC MEDIUM Local Area Network), allowing data and information to be exchanged between units, for a maximum of 15 units. This enables the reduction of the number of graphic terminals, since a single shared terminal can monitor all boards in the network.


    Managment of units up to 2 frigorific circuits and 4 SCROLL compresores with electronic expansión valves, indoor EC plug-fans, outdoor axial fans (EC or AC 2 speed), energy recovery and many other options.
