After doing further testing with e+ 8.9, it turns out that the dx heating coil (Coil:Heating:DX:SingleSpeed) can actually operate below -20 DegC. The limitation is then not in e+. My original testing for this was done using OpenStudio which always sets a minimum value of -20 DegC on the the minimum outdoor temperature for compressor operation. This was last verified with OS v 2.6.
