Trying to understand TSB, CTL, TSS values

[Valerun]

Hello there!
I 've just bought a new Suunto Peak pro watch and I have a little difficulty understanding the functions TSB, CTL, TSS… The values are not represented in cents, and I cannot understand the meaning of the numbers going from - 10/20 to 300/400…for me they are just random numbers… And also the difference between TSB, CTL, TSS… The manual didn’t seem so clear to me about it… anyone has an easy explanation?
thank you all!
Valentjna
