ERV FAN SETTINGS
ERV Fan Setting
The ERV fans are factory set to default position. It is recommended to perform an air balance to determine required
fan speeds - Low and High. The potentiometers located on the ERV board controls the Low and High fan speeds.
These speeds are controlled using a PWM signal from 0% to 95% Torque. The range of the potentiometer is 8
o’clock to 4 o’clock.

Notes:
• All airflow ratings are taken at lowest voltage rating of dual rating (ie. 208 volt).
• ERV external static setting is based on exhaust duct run.
• ESP capability shown per fan.
• Recommended ERV fan speeds are field set to match duct static. Default factory settings may not match site conditions and
requirements.
• Watts includes both ERV fans.
• Internal Manual OA Slider Damper may be used to control OA introduction in the event of variable OA conditions (i.e. wind stack
effect)
