[EnergyPlus_Support] Heat Recovery Option for Compact HVAC: Unitary apprears to not work

["jim_mcnally" <jim_mcnally@xxxxxxxxx>]

Hi,
I have been trying to simulate a unitary HVAC device with a heat 
recovery module. I am using the Compact:Unitary equipment simulation. 
The heat recovery option does not materially change the energy use 
results.
A one zone building with one rooftop unit is my quick running test 
model. The compact unitary part is given below.

Am I missing something?
Regards,
Jim McNally
