Another of my early settings
Normal sudoku rules apply.
The digits in the thermo must be strictly increasing in each cell from the bulb up the line.
All adjacent cells with two digits summing to 5 are marked by V, while those summing to 10 are marked by X. The cell edges which do not contain an X or a V cannot have digits summing to 5 or 10
Solution code: Row 8, Col 8
