Control unit that controls electrical loads designed for the management of absorbed power. In case of simultaneous startings of domestic appliances, the device prevents the disconnection of the general switch by disconnecting a not priority load if the power absorption is higher than the set value (setpoint), avoiding a blackout. It is coupled with one or more remote actuators RX.16A. Control unit and actuators communicate by radio-frequency signals, without having wire connections between the devices. The control unit PC RF8 can control maximum 8 remote actuators.
