ZAMEL Extra Free - Programming of mono/bistable operating mode

Welcome.

This is about the ZAMEL Extra Free ROP-02 2-channel box receiver.
Unfortunately, the manual does not clearly state.
"The device can operate in one of five modes for each channel" - radio I understand.
Does this "channel" also include the IN1 and IN2 inputs for connecting mechanical buttons?

Because I don't know if I should replace the light switch on the wall with a "bell" (momentary) switch?

This controller has 2 channels -1st radio channel (remote control) and IN1 + 2nd remote control channel (IN2)
When programming the operation of the 1st channel, you define the operation of the IN1 input, similarly with the 2nd channel. For pulse control, you must have a bell button (control of only one channel 1 or 2, depending on the connection) or a roller shutter switch - without backup, you can control two channels with it (pay attention to connections).
