I trying to model a ground source heat pump system using
Type557-a and Type927. I would like to control the outlet
temperature of the load. However, as I was reading in old posts
and testing in TRNSYS, Type927 has a constant speed compressor.
I was trying couple of control strategies but none of them was
able to control the outlet temperature of the load.</div>

Is there any water-to-water heat pump type which I can control
the outlet load temperature or any control strategy?</div>
