Does anyone know if it is possible to set up a sleep timer action with any of the Prontos. I am pretty sure you cannot do it with a TSU 2000 or 6000. What I am looking to do is create a button that will execute a series of commands (macro) after a 15,30 or 60 minute delay.

not really:

All Prontos and Marantz

1) Create a button called sleep timer with 15,30 or 60 min delay and then off.

con while the macro is running the remote is useless, but you can stop the macro by pressing the button again

pro is what you want

on the 1000/2000/6000

2) create a timer that ends at the same time every day (let's say 3AM)

Pro easy to do and does not create problems like the delay

con not what you want, might want to run it latter some days

3) like 2 but edit the timer every day

Pro you can make it for any time/day you want,

con editing time is a pain

4) create a panel on the macro side full of buttons with timers set on to be at X:00 and off to be at X:30 with action turn equipment off. And don't set any days. Then when you want it off all you need is to click the day

Proalmost what you want, easier to use then 3

con need to be in edit mode makes it a bit more complex.
