Enraf 854 - Vito 762 Setup Codes

To configure a Enraf 854 for a Vito 762 temperature system, via either ENSITE or PET, what two character codes do I need to "implement".

I have compared to one other already operational on-site - and all codes or "items" shown below are the same, however for read only items such as MU (test resistance) and U0-U8 I only read default values on the new instrument and actual real life values on the existing.

I currently have: MN=16 ; MT=TPL ; TU=T ; TD=C ; TE=PT100 (same on both instrments).

Is there some step that I am missing in setting up the 2nd/new unit?

Thanks
