A month ago, PTV stopped regulating the temperature.
When the temperature is set to 250⁰С , it actually shows 60⁰С when measured.
It is possible that the factory settings in the PTV configuration have been reset.
In the attachment there is a photo of the PTV inlet configuration.
I Looking for an installation guide for a PTV inlet for GC 8890 and how configurated heater parameters in service mode.
Please help with solving this problem.
