The radio receiver comprises a second micro-controller with a second code memory, that at each signal being received with one of the codes of said second memory, generates a control signal for a control unit provided with a third memory that, upon reception of the control signal, starts the motor in one sense of rotation or in the opposite sense according to the identity of the push-button of the radio transmitter that is being pressed, and receives identification data of the angle of rotation from an encoder that is coupled to the motor, in order to allow the motor to rotate until it reaches a prefixed limit stop. The two micro-controllers and the control unit are programmed to allow the electronic setting of the position of the lifting and lowering limit stops of the roller shutter through a proper sequential depression of said push buttons. It is also possible to enable one transmitter to control a plurality of radio receivers.
