Benoit,
 In addition to Stephan's comment, I had also written a Type some time 
ago that is a triggered version of the delayed inputs component 
(Type661, which is quite similar to standard Type93). The only 
difference is that it delays inputs (like schedules) by a certain number 
of timesteps only when the "trigger" input is set to 1. We plan to 
release it with the TESS Libraries 3 and TRNSYS 17.
Kind regards,
 David
