<body class='hmmessage'><div dir='ltr'>Hello,<br><br>When I choose VAV system type in HAP, I get 3 options which are VAV, 1 Fan Dual Duct VAV and 2 Fan Dual Duct VAV.<br><br>I want to design a VAV system but with central cooling AND heating. When I use VAV, it doesn't give me the option to use central heating and I'm forced to use a VAV box with reheat instead. Is there any work around this?<br><br>Can I add the total of the terminal heating coil for each zone and just place a central heating coil with the same amount?<br><br>Thanks in advance.<br> </div></body>
