EV-Series Premium
ERV
1.0 OVERVIEW
1.1 DESCRIPTION
1.2 OPERATING MODES
The EV Premium ERVs are multi-speed air-to-air energy recovery ventilators that are designed
for residential application and have multiple installation options. They can be suspended from
floor joists, or they can be mounted on a wall or other object. Each type of installation can be
accomplished by a single person. The EV Premium has an integral line cord, ready to be plugged
into a standard 120 VAC receptacle.
The ERV exhausts stale room air (RA) while transferring both latent and sensible energy
between an incoming fresh outdoor airstream (FA). Energy recovery is accomplished by a static
plate heat exchanger core. Each airstream has a 120 V EC fan, which provides airflow from 30
to 225 CFM for the EV Premium M and from 30 to 280 CFM for the EV Premium L.
The airflow rate can be changed from Continuous to Boost at any time, using many different
optional sensors or control devices.
The unit may operate with balanced or unbalanced airflow. However, balanced airflow provides
the best energy recovery. Airflow can be adjusted using the motor potentiometers and the
values read via the door pressure taps.
The hinged door has an opening for viewing and access to the potentiometers. The entire
cabinet is lined with foil-backed 1" thick foam insulation.

energy is often

energy is often

The EV Premium has two different operating modes: Continuous and Boost. Continuous mode
should be set to provide the minimum ventilation requirement. Boost mode can be used to
supply and exhaust a greater volume of air, up to 225 CFM for the EV Premium M or 280 CFM
for the EV Premium L.
The two operating modes are selectable and controlled independently so that different
controlling methods can be used to switch back and forth. Example: an IAQ sensor could be
used to switch the unit to Boost mode.
