IntesisBox Modbus Server – Panasonic AC is a communication gateway for Panasonic air conditioning systems to Modbus slave (RTU and TCP).
This integration requires the CZ-CFUNC2 communication adaptor from Panasonic.

IntesisBox continuously polls (read) all the signals configured and maintains the updated values to be served in Modbus. When a write is done from Modbus in a gateway's Modbus address (allowed to be written), the corresponding order is sent to the AC unit signal associated.

IntesisBox is capable of managing up to two simultaneous Modbus master connections and includes all hardware needed to connect directly with the Panasonic indoor units connected to the CZ-CFUNC2 communication adaptor.
