You can use 668 to model an air-to-water heat pump. The component
is documented in such a way that the "heating on" control signal
condition means that it should heat <i>air </i>and that the
"cooling on" control signal condition means that it should cool the
<i>air</i>. However, if you just interpret those signals the other
way such that "heating on" means that it should cool the <i>water </i>and
"cooling on" means that it should heat the <i>water </i>then
you're modeling an air-to-water instead of a water-to-air heatpump.<br>
I don't recall whether Type668 has any desuperheater or auxiliary
heater features but if it does then you should disable those I
think.<br>
