recovery system (Renee's email). I set the ERV type to 'enthalpy wheel', with
the make up air temp ctrl set to mixed air reset & capacity control to '
trim economizer's (the design engineer suggested this was the closest to the
designed system). </span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

on the electric side in fans (this I had foreseen from additional static
pressure needed to drive the air through the enthalpy wheel) & space
cooling (this was surprising - especially since the base system had humidity
controlled at 50%). The space heating was the only thing which showed
considerable savings.</span></font><o:p></o:p></p>
