The XV Thermos (XV Series #3)

This is the third puzzle in my XV Series. Please double check the rules as these are NOT normal XV clues.

Rules:

• Where an ‘X’ exists between two thermos, the sums of the digits along those thermos have a DIFFERENCE of 10
• Where a ‘V’ exists between two thermos, the sums of the digits along those thermos have a DIFFERENCE of 5
• Normal thermo rules apply
• Normal sudoku rules apply
• No negative constraint

Example: If the digits along one thermo sum to 15, the digits along a thermo connected with an ‘X’, must sum to 5 or 25 to satisfy the sum difference of 10
