Type 1255 does allow the user to connect a time-varying zone air 
temperature.  If you're getting strange results I'm guessing you have 
something connected wrong or have made a mistake creating the soil data 
file.  I'd check there first.  We use 1255 quite a bit and it produces 
reasonable results for the soil and surface temperatures...
