Use a temporary lamp that is on the same
circuit as the controller or tranceiver you
are using to program it. You have 30 seconds
after the power is applied to the module to
program it. So turn ON the power and send an
ON to the address you want it on three
times. Like if you wanted P16. Turn on the
AC to the module and send P10 ON three times.
Verify it works and move it to the place you
want it. What controller or tranceiver are
you using?
