<div>Let me re-direct my question regarding reheating:</div>
<div> </div>
<div>How do I make my reheating (electric) work only(mainly) for cooling mode? <br></div>

<div>If I understand correctly, reheat Delta T, which was to specify max reheat coil capacity.</div>

<div>What I want is to switch reheat source from 'how water' to 'ectricity', while the heating source for </div>

<p class="MsoNormal"><span style="COLOR: navy; FONT-SIZE: 10pt">I need to model a VAV system with chilled water coil and hot water coil, and also with Electric Reheating.</span><u></u><u></u></p></div>

<p class="MsoNormal"><span style="COLOR: navy; FONT-SIZE: 10pt">As a start, I selected 'VAV with HW Reheat' system.</span><u></u><u></u></p></div>

<p class="MsoNormal"><span style="COLOR: navy; FONT-SIZE: 10pt">However, I've realized that the system only generates a reheating coil without a main hot water coil(heating coil).</span><u></u><u></u></p></div>

<div>
<p class="MsoNormal"><span style="COLOR: navy; FONT-SIZE: 10pt">So I installed 'heating coil' in the detailed mode, and then,</span> <span style="COLOR: navy">I changed the zone heat source to be 'electric'.</span><u></u><u></u></p>
