<i>heating only</i> mode to be doubled.  The PS-C/PS-H reports show the correct electrical energy but that value is doubled in the BEPU/PS-F/ES-D reports.  It is only the heating energy (cooling reports correctly) and only occurs when the loop-to-loop heat
 pump is in heating only mode with no assigned cooling load.  <o:p></o:p></span></p>
