Re: Systemair chiller code
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

Re: Systemair chiller code
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.
