Centralised control system for the management of a network of fan coil units and Cassette units with an electronic interface card (MB series) installed on them. Consisting of a hardware unit, box PC with Linux operating system and a pre-installed management software program. Network supervision function with the option of defining weekly operating programs and special programs for groups or individual units, with visualisation of data related to the log and any alarms. The system communicates with the MB network cards through a RS485 serial line Carisma Multizone is an advanced air distribution system intended for applications in residential or small commercial areas, suitable for centralised systems with the need to adjust the comfort of every room to individual needs. It can be applied on ducted Carisma CRSO and Carisma CRS-ECM fan coils. The system is fitted with an electronic control that can manage different temperatures through variable air flow rates in each air-conditioned area. The system is equipped with an electronic control that can manage different temperatures and air flow rates in each air-conditioned area. Thanks to the available controls, one can have a separate programming for the various areas; the system can also be interfaced with Modbus supervision systems. The motorised dampers are modulating devices with adjustable stroke and managed by the electronic control. The plenum is delivered with all its components (power board, regulator for asynchronous motor or ECM and motorised dampers) already assembled. The plenum and Fan Coil are equipped with quick-coupling terminal blocks. A wall-mounted controller flush with Multizone (also serving as an area sensor) must be provided for each system, plus a flush area Sensor for every area up to 4 per system (5 areas in total considering the wall-mounted controller flush with Multizone). The connection between the Plenum, wall-mounted controller and zone sensors must be carried out with the Multizone communication cable.
