<p class="MsoNormal"><span style="color:#1F497D">Hi Damon,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Can you provide the Carrier product sheet for the unit? A packaged DX unit will generally be natural gas-fired, though it could have a hot water coil. It would be unusual to have both, but you could model it
that way in a single unit if needed. (You could model a gas-fired ‘Furnace’ preheat coil along with a Hot Water Loop for the main SYSTEM:HEAT-SOURCE for example.) But you say there is no HW loop, so why would it have a HW coil?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I suspect you should model this as a PSZ system (“Pkgd Single Zone”, which only comes with DX cooling) with FURNACE for HEAT-SOURCE. Your ZONE-HEAT-SOURCE should be “Not Installed” unless you have a reheat coil.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-ZA">This may seem like a simplistic question as I’m new to eQUEST.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-ZA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-ZA">I am familiar with different cooling systems but not so much heating systems.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-ZA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-ZA">I need to add in a combined single zone DX Coil package with natural gas used for heating, from the specs I have I assume it’s a furnace with a hot water coil.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-ZA">It’s a carrier.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-ZA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-ZA">However in Equest there isn’t a combined system so I added in two systems one for the Single Zone DX Coil Cooling only then added in a separate entry for the heating as a furnace with a hot water coil.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-ZA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-ZA">I ran the model but when going into the detailed model I don’t see the hot water coil, if I add it into the heating tab then I need to add a hot a water loop and there is none.<o:p></o:p></span></p>
