<p>A device (1) for managing an electrical user comprises at least one electronic clock defined by a first programmable logic (3), interface means (4) connected to the electronic clock to transmit input and output data into and out of the electronic clock, a management relay (6) controlled by the electronic clock and connectable to an electrical load (2) and a second programmable logic (7), interconnected with the first programmable logic (3) and provided with at least one connection (8) to external control devices (9) to receive control signals of the management relay (6), so that, at pre-determined times, the first logic (3) acts on the management relay (6) and/or on the second logic (7) to cancel or modify the effect of the control devices (9), as a function of the settings received through the interface means (4) and of a remote control. In known devices, the clocks are connected to an electrical switchboard whereto are connected the management devices and any logic of the clock cannot change the effects of the control devices.</p> |
