Z offset using Bltouch

My printer has the Z min endStop assigned to the zmax pin and the bltouch connected to the zmin pin.
Can you help me set the Z offset? Please, I can not understand, it’s driving me crazy …I’m a Marlin user and, believe it or no, the Z offset settings was, in it’s own very hard way, much simpler for me.

With the following startup gcode of the Simplify3d profile to print a model, the printer tests the bed and works well, but the problem is that when it is supposed to start printing at a certain height (the height I am setting in the G30 command Zxxx in the start code) the printer ignores it and starts printing by hitting the bed with the nozzle, regardless of the value you are setting in the G30 command …

This is the startup gcode:
