Abstract
A method of controlling an electromechanical actuator (ACT) comprising a motor (MOT) for maneuvering a mobile appliance (LD) of a building in a first direction (DIR1) and in a second direction (DIR2) by way of a remote-control unit (RCU) and a unit (MCU) for driving the motor that are placed respectively one upstream of the other on an electrical power line energizing the motor with an alternating voltage, a command to maneuver in the first direction comprising a half-wave rectified signal of positive polarity and a command to maneuver in the second direction comprising a half-wave rectified signal of negative polarity, wherein the maneuver commands furthermore comprise an alternating voltage signal following the half-wave rectified signal.
