Panasonic FV-10VEC2R Installation And Operating Instructions Manual Download Page 4

The Panasonic Energy Recovery Ventilator (ERV) uses 2 blower fans driven by 2 DC motors. 

The motor is designed to have an extended service life with reduced energy consumption. 

It also incorporates a thermal-cutoff for safety.

The exhaust air (EA) duct includes an electric damper to prevent backdrafting. The outside 

air (OA) duct includes an electric damper to prevent backdrafting.

Energy Recovery Introduction: Compared to an HRV (Heat Recovery Ventilator), the ERV can

also transfer humidity and recover energy from that humidity. The ERV can exchange energy

between the stale EA and the “fresh” OA, transferring heat and moisture into the incoming

cold air in a heating climate and pre-cooling and reducing the humidity of the incoming hot

air in a cooling climate. This tempering and treatment of the required ventilation air helps 

maintain a fresh environment even when the heating or cooling system is not operating.
