Revision
• ERV
- Energy Recovery Ventilator.
• Defrost Mode
- to ensure reliable operation during cold weather, the ERV will automatically cycle through its defrost mode as
needed.
• Dehumidistat
- a control device that senses the amount of moisture in the air and activates high−speed ventilation when the air
moisture level exceeds the setpoint.
• Reset
- whenever resetting of the ERV is required, simply unplug the power cord for 30 seconds. The Self-Test will occur when
the ERV is reconnected.
• Self-Test
- each time the ERV is powered/energized, the self-test function will automatically initiate. During the self-test, the
ERV will cycle through all the speeds available (1 − 5), test the damper motor operation, and will default back to the previous
operational mode and speed selection. Total self-test duration is approximately 90 seconds.
• Standby Mode
- the ERV is powered/energized and waiting for fan operation to be initiated. For example, the ERV is set to
Continuous Ventilation Operation Mode at speed 0.
• Thermistor
- This is the temperature sensor that measures electrical resistance as outdoor temperatures fluctuate.
• HVI
- Home Ventilating Institute.
• HRAI
- Heating Refrigeration Air Conditioning Institute.
This equipment is designed to provide fresh air while exhausting an equal amount of stale air. The ERV unit is equipped with an
enthalpic core. The ERV unit transfers both sensible (temperature) and latent (moisture) between incoming fresh air and exhausting
stale air.
