Control device for an appliance adapted to assume a level selected from a range of levels, method of controlling a roller blind using the device, and user module for the device

摘要

A control device for an appliance which can assume a level selected from a range of levels includes a keypad representative of the range of levels to enable a user to select a level, an “off” key for switching off the appliance, and a processor unit connected to the keypad and to the “off” key. If the appliance is switched off and the keypad is operated to select a target level, the processor unit causes the appliance to assume the selected target level. If the appliance is switched off and the “off” key is operated, the control unit leaves the appliance switched off. If the appliance is switched on and the keypad is operated to select a target level, the control device causes the appliance to assume the selected target level if that level is different from its current level. If the appliance is switched on and the “off” key is operated, the processor unit switches off the appliance.
