    I currently have a DLT key programmed as a timer and want to retrigger the timer from a PIR that controls a different group.
    Do I simply programme one of the PIRs spare virtual keys with "function" as retrigger and "group" as the GA that I wish to retrigger the timer on.
    Thanks.

    Yes, I think that should work.

    The retrigger micro functions works as follows:

    If the group is off, do nothing
    if the group is on:
    1/if the timer is currently not running (in that device) Issue a ramp to level at the current level of the ga.
    2/ Start the timer.

    The DLT will turn on the group and start a timer.
    When the pir triggers, the group is on , so the retrigger will activate.
    Since the timer isn't currently running in the pir, It will send out a ramp to ON since that is the current state of the ga.
    This will cancel the timer in the DLT.
    The pir will then start it's own timer.

    You would then just need to set the expiry function to turn the group off.
