ZD-937 - Problem reading temperature

[mau80]

Hi,

I've a problem with this soldering station, it always shows TEMP 428°C, even if i detach the solder cable I get TEMP 428°C.
I've replaced the heating resistance and termocouple, the soldering iron temperature is hight, but it always display 428°C.

Let me know if I can provide other details to you.

Thank you very much to all!
