How to get wall boundary temperature?

I have a problem to get wall boundary temperature.
I used UDF.
If I use built-in function, it's fine.
That is, after calculation, if I want to know specific boundary temperature,
Report > Surface Integrals > Average area weighted(or others) > specific boundary check,
then, I know the boundary wall temperature.
But, when I use UDF, boundary wall temperature is differ from above result.
Of course, difference between two results is very small(approx. 1K), but this small difference occurs huge difference of results.
I would write my UDF Code.
Please tell me any idea.
Thread *thread = Lookup_Thread(domain, Surface_up); /* set up domain frost thickness, 12 for frost surface ID from B.C panel */
real x[ND_ND]; /* declaration the position variable */
F_CENTROID(x, face, thread);
temp += F_T(face, thread);
Temp_up = temp / 100; /* 100 is a number of cell along boundary */
