Device for controlling an apparatus able to go to a selected level among a range of levels, method for controlling a roller shutter with such a device, user unit for such a device

摘要

During an initialization period a processor (200) measures the time taken to move between upper and lower levels and this is used as a basis for controlling movement between a current and target level. The user control module (100) includes a keyboard (110) which signals positions by resistance, a stop button (120) and a diode display (130). The system may also receive commands from an external source such as a thermostat or weather station. An Independent claim is also included for the command process for a rolling shutter.
