The BL220FTX is the transmitter of the BL220F v2/Fi modular exhaust air safety system (with DIBt approval). It can be used if the receiver of the existing system is to be controlled alternatively by an additional window transmitter.
To do this, simply adapt the coding of the BL220FTX to that of the existing transmitter of the BL220F v2, or BL220Fi. After a new test phase of the new transmitter with the existing receiver, the two transmitters can smoothly control a receiver side by side.
