The red LED only flashes in teach mode, otherwise it is off. What were you doing with the white wire?
We tested it wrong, now that I see the wiring diagram. We thought the white was the common for the analog output. We wired the resistors between white and black, now I see we should have done, black and blue.

Will test again on Monday and Post results, and what values of resistors we used for divider.
