I'm unfamiliar with load management controls. I'm in a similar
situation, trying to mimic a boiler on a gshp loop.<br>
<br>
How can I control the boiler based on outdoor air temperature?<br>
<br>
Thanks in advance,<br>

<p class="MsoNormal"><span style="color:#1F497D">You can go to
the circulation
loop attached to the GHEX and create an artificial boiler
load under the
“Process/DHW Loads” tab. You’ll have to account
for your fuel consumption separately but you’ll at least be
able to see
how the artificial boiler loads impact the ground loop
temperature. <o:p></o:p></span></p>
