security and repeat

[VBX10]

I recently started with Active Home with Smart macro's.
I can't find any information regarding the repeat and security buttons in the timers.
What is their use and what are they doing?

Welcome to the forum and AHP.

Here's a Wiki article on your question (far better explained than anything I could provide): X10 Knowledgebase

Thanks
