  needs, the contents of this memory can be transferred to

  with the help of a button 26 in the RAM memory 19. Thanks to this

  25, the user can have a time switch

  preprogrammed while keeping the possibility of modifying its

  gram. The time switch according to the invention operates as follows:

  In the position represented by the cursor 14 on N (function

  normally) and for any position 1 to 8 of the cur-

  13, the bar 7 displays the daily program of the circuit

  considered for the current day and week. LEDs 12 cor-

  seven days of the week then indicate simultaneously

  for the week in question, the derogation profile of that week, while being switched on, off or flashing. the blinking of a light means that the normal program of the corresponding day has been, is, or will be replaced by the eighth daily program, a light on means that the replacement of the normal program of the corresponding day by the Sunday program has had or will have place, or that it is in progress, and a light extinguished corresponds to a

  the normal program of the corresponding day without any

  tion. The illumination of the indicator light 12 of the push buttons 10 and 11 signifies the advance or the delay of the one hour clock.

  during the week, these schedule changes being unique-

  carried out during the night from Saturday to Sunday.

  Actuation of one of the push buttons 15 or 16

  allows respectively the opening or closing of the cor-

  sponding; the following instruction will return said circuit in the

  position foreseen by the programming.

  The actuation of one of the push buttons 8 has the effect of lighting the lights 12 corresponding to the days affected by the same program as the selected day, and a display of said

  1 indicate the hours, minutes, and current day, which can be changed using the rotary knob

bidirectional 17.

  Holding cursor 14 on position N, and moving

2 2461972

  placing the cursor 13 on the position D, the numbers 2 and 3 of the display i indicate the number of the week whose profile of

  derogation is displayed by LEDs 12, and the profile of

  week, that is to say the weeks of which at least one day is assigned a derogation program, is displayed by 52 LEDs of the bar 7. The number of the week can be modified by means of the rotary knob bi By keeping the cursor 14 in the position indicated above, and by moving the cursor 13 to one of the positions 9 to 16, the numbers 2 and 3 of the display 1 indicate the number of the current week, and 52 LEDs of the bar 7 display the

  annual program of the selected circuit.

  When the cursor 14 is moved to the programming position P and the cursor 13 to one of the positions 1 to 8, the bar 7 displays the daily program. The bi-directional rotary knob 17 then allows, in combination with the buttons

  push buttons 15 and 16, programming or modification of the

  daily gram corresponding to the circuit selected by means of the cursor 13. The numbers 2 to 5 of the display 1 display the different set points selected in hours and minutes, and the pushbuttons 8 and 9 make it possible to assign the daily program considered to the days desired program, the eighth program may be identical to this daily program, which may, in addition, be assigned simultaneously to several days of

the week.

  Keeping the cursor 14 on P and moving the cursor

  13 at position D, the two digits 2 and 3 of the display 1 indicate the number of the week, which can be changed to

  button 17, and the pushbuttons 8 allow a

  derogation program, one button action

  pusher changing the state of derogation of the corresponding day.

  When the cursor 13 is moved on one of the positions

  9 to 16, the cursor 14 remaining on P, the bar 7 displays the annual program. The bidirectional rotary knob 17 allows

  then, in combination with the push buttons 15 and 16, the

  grammar or modification of the annual program corresponding to the circuits selected with cursor 13, and the two digits

  Finally, when the cursor 14 is moved to the position

  E, the switch according to the invention makes the recording

  programs, that is to say their storage in the

  RAM or RAM 19, and the display remains unchanged.

  Thanks to the invention, it is possible to realize a

  time switch allowing numerous possibilities of

  grammar and use with a small number of

  registration and order. Such a switch allows in particular the

  three annual derogations, namely, the allocation of

  to any day of any week of the year of the Sunday program for the eight circuits simultaneously, assignment to any day of any week

  an eighth daily program for the eight simul-

  at the same time, and keeping the circuits open one by one per whole week throughout the year, the latter derogation

having priority over others.

  Of course, the invention is not limited to the mode of

  embodiment described and shown in the accompanying drawings. Modifications

  cations remain possible, in particular by substituting equiva-

  slow techniques, without leaving the field of protection

of the invention.
