Did you install the system? Did you change any data?
Was it installed from the factory?
Did you replace a control unit?
Do you have a control module list? Do you have fault codes recorded on the network?

Everything was prepared (cable), just had to add the PTC heater, but I wonder where to activate it?

Is the PTC heater to heat the seats? Check the HVAC module. If you don't have a physical button for that things might get tricky.

PTC heaters usually are used to pre-heat the air for the cabin if the engine is not warm enough. Early Mk7/Mk7.5 models came with one as the engine was not hot enough quickly (especially the diesels). Don't know about the Mk8 though. On the Mk7/7.5 it's enabled by setting the PTC heater in the IPC/BCM main configuration.

it's run from the HVAC module. So the code for it is in there somewhere. No idea which bit though. You'd have to make some comparisons.
Unlike some other Fords where it's CAN controlled, the Fiesta has 2 relays which power it and just get signals from the HVAC module to power them. I think one relay runs half power the other full power or something like that
