I have a unique system I'm trying to setup in Equest and was wondering if it
is possible, and if so, what the trick is.

I would like to couple a VAV system to water-to-water geothermal heat pumps.
So essentially I will have a VAV system on the terminal side and the heating
and cooling plants will be geothermal water-to-water heat pumps. One will
feed the chilled water coil in the air handler, and another the reheat coils
at the VAV boxes.

I can set up a heat pump chiller that feeds the air handler with a
geothermal condensing loop. But I'm having problems attaching a heat pump
to the hot water loop, and the hot water loop to the geothermal condensing
loop.

Thanks for any insight you might have. Hope everyone has a nice holiday!
