Normal Sudoku rules apply.
Standard Thermo Sudoku rules also apply (digits must increase along the thermometers from the bulb end).
I know it looks like a lot of them, but it is not as easy as it seems... hopefully.
Enjoy!
Solution code: The code is all the digits in the second box (starting from R1C4) in reading order.
