have you got the evd interface? its been a while since i needed to use my interface but im sure you can set the superheat ect on that?

[TrickyRikki]

If you have the evd interface the 2 passwords you require is:

22 = Service level password
66 = Manufacturer password

Hopefully they will get you where you want/need to be

If you download the instructions for the eev they will give you the above codes.

Did you manage to sort the issue with them codes?

Default CAREL passwords will always be "1234" or "0000" - anything else and they've been configured by the OEM/Panel Builder in order to stop engineers interrogating set points without consulting them!

As above poster mentioned, you can use the EVD display (EVDIS00EN0) to adjust set points such as super heat.
