Binding LCD paanel to processor

Which type of Unison processor do you have?

It will either be the older Unison processor with a two-line text LCD on it, or the newer Unison Paradigm with a multi-line LCD.

If it's the newer Paradigm processor, you will also need to check the firmware version of both processor and LCD:

• Paradigm Processor:
  3 digits bottom-right of the home screen, or all six digits in "About" > "Version Info" > "Paradigm ACP App"
• Paradigm LCD:
  Touch "Setup", and it says the "firmware" version in the "About" tab.
