Sorry Eddy, I didn’t asked properly.

My question was meant, how is runaway protection implemented in the Klipper code?

I’m a safety nazi, better save than sorry! Means, avoid fire risk in the first place and electrical risk second (that’ll probably hurt just me)!  
Living in an apartment house, I try very hard to make sure not to start a fire!  
Hurting anyone with my hobby would also be fatal for me. I guess, I couldn’t continue to live.  
Before starting FDM printing, I build this, use it and check it every 3 month.

Your link didn’t help answering my question.

Again, my question was about how the runaway protection of Klipper works.

I guess this is a starting point to understand that.  
[Configuration reference - Klipper documentation](https://www.klipper3d.org/Config_Reference.html) Search [verify\_heater].  
And of course the min\_temp and max\_temp settings.
