Hi All,

Does anyone know how to set a loop to loop heat pump chiller control so that
the ground water return temperature stays above freezing? Even though I have
set constant flow everywhere I can find, the gound source flow is reducing
below the set value and the temperature is dropping below freezing. (This is
a pure water system, so I need to limit the winter chiller operation to the
ground loop's heating capacity.)

Any suggestions will be greatly appreciated.

Regards,
