I've learned the user manual of Gira tastsensor 3 +.
I've some concerns about the usability of the setpoint shift.
I find this not practical. For shifting the setpoint, i need to:
  1. touch the first rocker
  2. then touch again the first right rocker to confirm that i wish to change the setpoint
  3. then i need to change the setpoint with "+" and "-"
  4. then i need to confirm the setpoint by touching any of the other rockers

A simple touch of right or left rocker would be more simple.
What do you think about?
Thanks.
