work. Make sure that the left LED is green before
proceeding.

1.
Remove power from the controller.
2.
Press and hold the REX button.
3.
Apply power to the unit with the REX button pressed.
4.
Release the REX button.
5.
You now have 15 seconds to program a new programming
code into the unit using the initial default code before the
controller reverts to the existing code.
The deafult code depends on the PIN length selected (see
Table 2).
