Replacement SD1000 / SD1800 Controller circuit board aka Simtech

Remote control codes can be set to your original code by matching the 8 small white coding switches of your original circuit board.

Note: These sliding gate openers were also shipped with a different remote control receiver and don't have the 8 small white switches to set the code (remotes shown below). In this case you will need new remotes to work with this new control board. We can supply these if required.
