Thanks mate. I have no problem with Gain/Offset settings at this stage. Regulating the cooling in Maxim DL is the issue.

It goes up and down the full range from ambient down to maximum cooling then does it again and again even when I start the warm up sequence at the end. It reaches ambient then the TEC kicks in again full blast. This is very very weird. I don't know if it's a software issue at this stage or a hardware problem with the QHY9.

Power supply is a steady regulated 12.2V input from a lab power supply at the moment.
