Abstract:
1. A method of operation of an installation (INS) comprising: applying an AC electric voltage to at least one actuator (ACT) to drive a movable element (LD) equipping a building, in a first direction when the AC electric voltage is applied between a neutral conductor (AC-N) and a first phase conductor (COND detecting an item of information at a level of the actuator; initiating, in response to the detection of the item of information, a sequence of one or more switching operations at the level of the actuator, said sequence including at least one switching making a direct contact between the first phase conductor and the second phase conductor or one switching breaking the direct contact between the first phase conductor and the second phase conductor.
