Module for exchanging information by carrier currents and method for managing the operation of said module

The module (22, 24) which is used in order to control an electric portion (12, 14) and which exchanges information by the carrier current is equipped with 1st means (34A, 36A) to receive a communication-of-information signal. The 1st receiving means (34A, 36A) -- two states -- that is, a state and a non-operating state can be taken, respectively. A module (22, 24) is equipped with 2nd means (34B, 36B) that starts the 1st receiving means (34A, 36A), and can be switched to an operating state from a non-operating state again to receive a seizing signal.
