Bus or Mains Voltage Recovery Function
The behaviour of the blind/shutter channel can be specified when the bus voltage or mains voltage
recovers. There are three possible selections for recovery situations:
Unchanged: The blind/shutter channel does not respond the bus or mains voltage recovers.
Upper Final Position: The blind/shutter travels to the upper end position.
Lower Final Position: The blind/shutter travels to the lower end position.

Feedback Functions
For blind and shutter channels there are two types of feedback functions depending on the blind
mechanism:
Height level feedback function
Slat level feedback function
Slat level feedback function is available for Venetian Blind mechanisms because of their slats. Height
level feedback function is available for both venetian blinds and roller shutters.
Slat and Height feedback objects are 1byte objects that sends the blind height level and slat level to
bus. Each channel has to be participated to feedback functions from the “Send slat feedback” and
“Send height feedback” parameters. There are three possible selections in these parameters:
No :
Do not use feedback.
Yes, only on change:
Use feedback only when the blind level is changed and send the blind
level to the bus.
Yes, cyclical and on change:
Use feedback when the blind level is changed and cyclical and
send the blind level to the bus . The cycle time can be set from Blind General parameter page.
