I set the minimum OSA in all zones to zero, with no economizer my annual
energy is 836,000 kWh annually.
With the economizer selected the kWh went up to 844,000 kWh annually.
Climate is CZ06 and the area is a Basement. in the detailed reports the
difference in temperature between outside and inside is -10+ and there is no
OSA flow at all.
no matter what i do I cannot get any benfit from economizer
