how to determine that my system has C wire or not null

Hi Nunu, thanks for the question. You can determine if your current wiring has a C-wire by checking the thermostat and look for a wire connected to the C-terminal or have a unused wrapped in the bundle. If you don't, you can follow your thermostat wires to the system and see if you have a C terminal available, this is where the adapter is going to be installed.
