A time switch, including means to adjust a valve temporarily assigned (3, 7, 8) give initiation command (13), decompose the assigned valve and transmit a signal (15, 17) at the end of the cycle, has a means (3, 8) to inhibit unauthorised adjustment of the assigned valve. The inhibition means (3, 8) has a means (8) to memorise an authorisation codes, means (21) to capture a coder and a comparator (3) allowing valve adjustment on correct code input.
