This came with a package deal when I needed a new PR511. I was able to change the house code to mine without problem. Since the new PR511 was set to Unit Code 1 and the default for the first On/Off pair is 1, you can guess what the first test was. Success! It turned my new PR511 on and off smartly.
But, I really wanted to use it to flip on the living room lamp when arriving home from a trip after dark, so I needed to change the unit code to 8. I followed the instructions precisely, but no joy. It would not control the lamp, which works just fine from my other RF controller and Mini Timer. They I tried to change it back to control the PR511, Unit Code 1, but was not successful. Now, it controls nothing at all. What am I missing?
TIA
