LOR1600 Controller won't retain ID number

I am having a little problem with 1 GFCI tripping. When it does, one of my LOR1600 controllers (#6) resets to ID #2. I reset the ID in the Hardware utility and all is fine for a couple of days untill it rains and then the GFCI sometimes trips, and the controller resets to #2 again.

The internal rotary switch is in position #6. I have rotated the switch (in case there might be a dirty connection inside the switch) and it still goes to the wrong ID#.

This happens whether or not the GFCI trips or it is simply unplugged. Whenever it loses power it resets.

Any ideas are appreciated. Is there a firmware update for the LOR1600 controller? I don't see it listed in the firmware list of files. Or would it it be as a different name?

Thanks in advance for any ideas. I am running fine-except for this little issue.

Any time it powers up, it will try reading the switch.. It sounds like the #4 switch is not working, resulting in the setting of 2. To get the hardware utility set address to stick, try this:

Remove power.
Set the id dials to 00
Put a jumper on the second row of pins from the top of the header
power up, and verify the ID with the hardware utility. Set if necessary, then test the ability to retain through power cycle.

As for firmware, note the color of the circuit card. Then look for firmware for a CTB16D controller of that color. If the unit is less than a year and a half old, it will likely have 4.40, and will not run any other version currently available..

I have heard of something like this. Not sure if this is the same thing or not. Do you have a dual row of pins? About 9 x 2. And is there a jumper on the 2nd pair down? If so, remove the jumper and rotate both rotary switches to zero and power up for a couple seconds. Power down and then rotate the switches to what address you want. I believe that it is 06 per what you wrote. Then power up and see if it is now unit #6.

Hope this is what the problem is. On units that have rotary switches that set the addressing. From what I understand is that the jumper is for setting the address via the hardware utility.
