color:#1F497D'>The dictionary says the heat pump designation for heat source is
an electric air-to-air. So I had always thought to just make the heat
source be the hot water loop fed to the heat pumps. Although when I make
the heat source a hot water loop and zone heat source a heat pump I do not see
an electric load for space heating. I would also be interested in
learning more about this.<o:p></o:p></span></p>

<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Hi,</span> <br>
<span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>The system I am
trying to model in eQUEST is a series of heat pumps that are connected to a
ground loop heat exchanger. I set up the heat exchanger and water loop in the
water side tab. I selected the 'water loop heat pump' option on the air side
systems and assigned the ground loop to it. There is a place on the cooling side
to assign the loop to the condenser. However, I don't see anyplace on the
heating tab to assign the loop to the heating side of the heat pump. I am also
getting 46% of my heating hours outside the throttling range (guessing this is
because there is no loop attached to the HP). Is there a fix for this? Should I
be using a different system type?</span><o:p></o:p></p>
<p><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Will Climate
master's extension allow me to model this better?</span> <o:p></o:p></p>
