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)
