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 potention-
meters 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.
