My 1st choice was 4-pipe fan coil with no cooling. Then someone told me to run DX cooling with a hot water coil (again, cooling zeroed out).</div><div><br></div><div>The DX approach causes a heating increase of approximately double the energy. No pumping energy increase. Fans have airflow but zero HP.</div><div><br></div><div>What could be causing this?</div><div><br></div><div>Thanks.</div><div><br></div><div><div class="MsoNormal"><a name="_MailAutoSig" href=""><span style="mso-fareast-font-family:
