This will avoid the necessity to relocate the FCM. Some time in the future when the system behaves well, I can convert the controller to V3 if you return the controller back to me. I don't charge for doing this, but you have to pay the return shipping.

Sure, I can solder a little bit so if you could send me the instructions. This is a temperature related issues it seems. Runs normal during cooler times and starts acting up up when it is hotter outside.
