Summer Bypass Summer Bypass is designed to operate during hot periods where
fresh air can be vented straight into the property without being
preheated by the extracted stale air. Summer Bypass operation is
automatically controlled. The Summer Bypass mechanism diverts
the stale air being extracted from the dwelling around the heat
cell so that its heat energy is not transferred to the fresh air being
supplied to the property.
