2100 Controller: Procedure to replace the old analog + digital boards with a single board

1- Take pictures of the current board cable installation to use them as reference

to install the new board.

2- Remove the 3 screws from the old digital board (see picture below).

3- Detach the J1 connector from the analog board (see picture below).



4- Now proceed to remove the old analog board, 4 screws


5- Place the new controller board on the bath, and use the 4 screws from the old board to secure it to the bath’s frame. Please notice that all the connectors on the old and new controllers are located very much on the same areas.  So, you shouldn’t have any issues in connecting them to the new controller.
