Andy,

I'll admit that when I first looked at this that I thought you had just 
simply screwed something up - but you are 100% correct.  I traced the 
error back to the Units.lab file which is located in the Exe directory.  
Somehow, at some point, the leading + signs were stripped from the unit 
conversions in this file.  I've updated the file and we'll release it 
with the next TRNSYS release but if you want to fix it now it's pretty 
simple.

For each of the conversions in the file simply add a leading + to each 
numerical value.  So

TE2=øF           1.80000E+00   3.20000E+01

becomes

TE2=øF           +1.80000E+00   +3.20000E+01

There should be seventeen characters before the first + sign, a 
12-character number (including the + sign), 3 spaces, and then another 
12-character number (including the + sign).  Make the fix for all of the 
units in the file.  Or simply e-mail me and I'll send out the file to 
anyone that wants it.
