I am trying to simulate a heat-recovery system in DOE2.1. 

If I choose a SZRH system with 65% heat-recovery, I get the expected mixed
air temperature values:
-9°F outside air
72°F return air
64°F mixed air

If I then replace the SZRH with a RHFS, the heat-recovery then doesn't seem
to work:
-9°F outside air
72°F return air
51°F mixed air

Can anyone help explain this anomaly?
