1- Confirm the colour of the casing of your remote control: it must be GREY. If it is green with yellow buttons, then the correct model is the one from Doitrand, which is not compatible.
2- Confirm that either CASIT or CASALI is not written on the casing. If it is, then the correct model is the one from CASIT or CASALI, which are not compatible.
3-Finally, open your remote control and confirm that it contains small switches for programming. If it does not, then the correct model is the Prastel MPSTF2RE, which is not compatible.
