<p>The control device is for a group of electrical loads (2,2A,2B,2C) typically lighting or rolling shutters which have an overall control box (3) and individual electronic units (A) at each load. The group has a common electricity supply (4) controlled in each electronic unit (A) by a switch (5) (COM). The electronic units (A) also have a processor (8) (UT) with a memory (13) and a domestic interface (9) (INT DOM) which may consist of a carrier current or infra red system to provide communication between loads. The operation of a load (2) adjacent to the control box (3) may be made conditional on the correct operation of the other loads in the group.</p> |
