Lossnay
®
core at all times.
Bypass – no exchange – bypass damper open.
Automatic – energy exchange or bypass as
determined by present temperature sensor in inlet
and discharge airstreams.
Balanced Ventilation
A ventiliation strategy using both an exhaust air
blower and a supply or make-up air blower provid-
