i just received 5 of the lutron MRFA-600m-urc dimmers and after 1 hour of messing around with the URC downloaded controls and programming the dimmers, let me be the first to say i had a heck of a time getting them to work.

more than 50% of the time after pressing the button on the remote the dimmer fails to receive the command, and you have to hold down the button for it to work. The scenes dont program the way they advertise.

i tried to control them thru a mx3000 and a kp-900....same results both time.

After considerable time with URC technical support, i found that i have to install macros under every button, adding time delays and repeat functions under every comand line to get it to work properly. sometimes adding 5 repeat comands for every macro. but now it is working properly.

man. i love the control i get, but the programming is a real nitemare IMO.
