Unit Overview
Basic Unit
The unit is prewired such that when a call for outside air
is made (via field-supplied 24 VAC control signal wired
to unit control center), the supply and exhaust fans are
energized and optional motorized dampers open. The
unit is normally interlocked (24 volt) to the rooftop air
handler. When the rooftop air handler starts, the auxiliary
contactor in the air handler closes to start the unit.
Summer Operation
Outdoor air is preconditioned (temperature and moisture
levels are decreased) by the transfer of energy from the
cooler, drier return air through the energy recovery core.
The preconditioned air is typically mixed with return air
going back to the air handler for final conditioning.
Winter Operation
Outdoor air is preconditioned (temperature and moisture
levels are increased) by the transfer of energy from
the warmer, more humid return air through the energy
recovery core. The preconditioned air is typically mixed
with return air going back to the air handler for final
conditioning.
