Good remote control but with "bitter aftertaste"

The ITZ-500 should be able to turn 256 articles, which indeed is true. But it can be controlled effectively only 16 articles. The ITZ-500 remote features like all other InterTechno via a channel rotary switch on the back. If you want to drive more than 16 items is forced to change the channel using the rotary switch on the back. This is cumbersome and unreasonable (the rotary switch läst only with a screwdriver continue turning / turn).
I turn in my small apartment house 20 terminals (has ITZ-500 for 12 memory) both via the timer or manually. Since then, unfortunately, still a 2 remote control needed.

Here the engineers could come up with a better solution at InterTechno!

For the control of 16 articles on timer and keys I can only say that I am very satisfied and the ITZ-500 can unreservedly recommend.
