How to set and display the values on Linea PID

[@genericgymvlogsph9739]

Hello do all Linea Classics have this PID controller?

[@Kyle900t]

Older ones don't.

[@krissadasaelim9985]

Pls let me know this PID measures the boiler temp or groupheads temp?

[@alihamidi2883]

PID measures for groupheads temperature.

Hi how do you default the PID controller to factory default settings ?

Hi Mervin, send an email over to [e-mail] our After Sales department. They will be happy to take you through the steps.
