We're trying to change a TIU address from three blinks to one blink (from ID 3 to ID 1)
Even with the TIU off the layout and the remote tethered, after changing the ID to 1 the TIU still comes up blinking 3 times when powered up.
Looking at it in the remote it thinks it's 1, but the TIU thinks it's 3 .... by the blinks.
Any idea what is going on?
Is the TIU "bad" and needs to go to a TIU Doctor?
