I Have bought a 2.hand lintronic 238 box, but the box does not seems to react on 2-ways signals from my BL5000 - I have to change the setting to 1-way.

Is there anyone using the 238 box with a BL5000/BL7000 in 2-way mode ?

I am sure it won't work in two way communication - two way devices send a confirming signal back to the remote which the Lintronic box will not do.
