The controller lets you emulate a number of DIP switch settings directly in the display (in older versions of the controller you had to open the cabinet a physically flip the switches.) A DIP switch can be either open or closed, and the TWC NV behavior changes according to these settings. Each DIP switch concerns a specific setting area - the table below explains which DIP switches can be toggled, the setting area they concern, and what the different settings mean.

Note: Changing the settings for DIP switches 1-5 has no effect on the controller.

1. Place the controller in SETUP mode.

2. Scroll to 6 Switch Settings (if you have already changed switch no. 10 to "Closed" it will read 7 Switch Settings instead) and press the ENTER button. The display will look similar to this: 

The top row of numbers (2109 8765 4321) represents the 12 switches. The 2 is short for 12, 1 for 11 and 0 for 10.


3. Use the item selectors to toggle between "O" for Open and "C" for Closed. Press the ENTER button to advance to the next switch setting. After saving the setting for switch number 5, you will exit the menu, as switches 1-4 cannot be edited.

4. If you made any changes to the switch settings you will be prompted to reboot the controller. 

5. Press the ENTER button to restart the controller or the CANCEL button to cancel. If you accept the restart, the controller will restart in about 30 seconds.
