You are looking for words like scheduled, automatic and periodically. You can use a thesarus to find alternatives to these words, but here are some examples:

  • "You can schedule times for programs and services to run" (or "You can schedule the times at which programs and services run.")
  • "The program offers many built in commands such as (X, Y, Z) that can be scheduled to run automatically"
  • "The program will periodically check your dynamic IP address and send an email notification each time it changes."

The word you are looking for might be periodically. Swap it in your sentences, and it seems to make sense.
