Chinook RV

Does anyone have one of these shown in the photos?
I have a 1997 Chinook that has an additional box with a circuit board inside. It has a button that when pressed shown a display code of LL. It is hooked into the thermostat. I have no idea what it is. Everything works as it should but I am just wondering what it is for.

Never see one before. Does it has any identification or name on the unit?

Here are 2 more photos. showing the readout that it has when I press the button. and the circuit board with the only information on the little white tag.

This is going to e difficult unless someone have seem one before. Without identification, I can't really help you. The white label is for quality control purpose. Sorry. Hopefully someone can help you out.

Maybe post the picture on facebook group and see if there is anyone there that have one of these. Good luck.

Just a guess....Is it upside down? 77 degrees?
It also appears that it requires a 9 volt battery?

I think you are getting something there, RLB. My wild guess is that it will display "LL" if the battery is missing.... but more importantly, what does it do? Maybe beeingbill can send the module to you, and you can give us the schematic as well as a manual.

Put in a new battery but it still displays LL and it's not an upside down 77. Still don't know what it's for but everything works O.K. so i am not going to worry about it.

I guess the battery is for backup in case the coach is turn off from 12 VDC? A mystery that we may have to live with.

I been in my current house for more than 8 yrs, and I still can not figure out what a circuit breaker do.... have been flipped it to off for years, and as far as I know, everything in the house works... It is 50A too, so not a small load.
