Product Description

Fan coil controller C2.FCC.03 is a universal FCU controller designed for a wide range of tasks in building automation, Smart Home, Guest Room Management System and for usage in two-pipe applications.

Primary communication channel is used for communication with BMS and supports BACnet and Modbus protocols. Secondary communication channel can be used for communication with local room display unit.

Full programmability and a multiple number of I/O enables the usage of the device not only for various types of FCUs but for other applications as well.

Programming is done in functional block diagram language using jPLCPro IDE.


* Only one fan speed relay can be active at the time
** If one stage relay is active at one time maximal current is 16A, if two stage relays are active at one time sum of both currents must not exceed 20A and current through one relay must not be greater than 16A
*** When device is powered only from auxiliary power supply I/O functionality is disabled
