Abstract
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 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 off and the “off” key is operated, the processor unit leaves the appliance off. If the appliance is on and the keypad is operated to select a target level, the processor unit causes the appliance to assume the selected target level if that level is different from its current level. If the appliance is on and the “off” key is operated, the processor unit switches off the appliance.
