<div dir="ltr">I also have a follow up question. Is there any system type that I can use which will allow me to select heat pump as the heating source and also be controlled by the supply air temperature? It appears that constant temp control would be available for PMZS but I cannot use heat pump heat with this type of system.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Apr 18, 2016 at 9:37 AM, Michael Campbell <span dir="ltr"><<a href="mailto:mcamp1206@gmail.com" target="_blank">mcamp1206@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div>Hello,<br><br></div>I'm trying to use a PSZ system as a DOAS. The system I'm trying to model uses and ERV tied to a heat pump to supply fresh air to common areas and dwelling units. There are then separate VRF systems for space conditioning. The DOAS is designed to supply a constant temperature outside air (73F when heating, 75F when cooling). How can I make the PSZ system in equest supply a constant temperature supply air?<br><br></div>Thank you<br></div>
