If you don't know how to write the code why not just split the wall into smaller sections in the geometry so you can define the temperature for each small section individually. You may end up with alot of small sections but its a work around solution to save having to figure out how to program a UDF

You can create a text file (.PROF) and read it (File-Read-Profile). This profile file needs certain format. You can find it in documentation. For ready reference I am giving a specimen for two data points referred by you. x, y in meters and temp in K.

((airinlet point 2) (x 370 370 ) (y 0 50 ) (temp 873 923 ) )
