    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.
