For the parameter table file I'm using to identify the height parameter, use 
HGHT rather
than HGT (I'm actually using the GEMPAK $GEMTBL/grid/g2* tables).

The NMAP2 configuration file for the defined plots is: $GEMTBL/nmap/mod_res.tbl
In this file you will find that the 850mb_THTAE_ADVECTION plot uses the .nts 
format
restore file: $NMAP_RESTORE/stnd/850mb_thtae_advection

The GDPFUN line for that plot is:
GDPFUN  adv(thte,wind)!sm5s(hght)!thte//te!te!te!kntv(wnd)
based on that, you need:
TMPK and RELH for THTE
UREL and VREL for WND, 
HGHT for HGHT

The CONDUIT data stream contains ".status" files with an inventory of every 
product inserted for
a data file. Eg:
% notifyme -v -l - -o 3600 -f CONDUIT -h idd.unidata.ucar.edu -p 
".status.*0p5deg"
.status./afs/.nwstg.nws.noaa.gov/ftp/SL.us008001/ST.opnt/MT.gfs_CY.12/RD.20060412/PT.grid_DF.gr2/fh.0024_tl.press_gr.0p5deg
 000293

If you broaden your request line to include "(0p5deg 
.*/(HGHT|otherparms)/|.status.*0p5deg)" you
will receive the status files which are text, and detail every level/parm 
available. I post the
.status file contents as a check for our data reception at:
