Maybe you bought it like me from Exclusiv-Home in Germany?
They sell TSU7500's from the USA, modified for 433.92 MHz.
They have several codes for "Rolladen" (actually Rollade is a meat dish in Holland -grin-).
Please PM to
barendh@xs4all.nl if you want me to send you what I have.
Funny enough, my 7500 pesters me every night at exactly 2100h and says it wants to close the Rolladen.
But I don't have any!
Must be in the adapted firmware...
