The CM15E and SW10E are both European model devices.
Is your power 240 volts 50Hz?
Ours are all 120 volts 60 Hz. and will not work in most other countries.
The SW10E is a special function switch. Are you trying to do things like open and close a blind or awning? It controls a directional motor by dim and bright commands or can do full on and off commands.
I just read the users sheet again.
The SW10E does have local buttons.
