NOTE: Pressure sensing ports are provided on both sides of the
ERV wheel for testing and balancing.
UNITS WITH EZERV CONTROL OPTION — With
the EzERV option, the LCD display will change to show the
amount of air moving through the cabinet in cubic feet per
minute (cfm). The screen is divided into two columns: The left
column showing the amount of outside air (Osa/CFM) and the
right column showing the exhaust air (Ext/CFM). To adjust the
fan speeds, remove the small panel next to the control panel
cover to access the user input controls. See Fig. 16.
Fig. 16 — LCD Display
Balanced Air Option — Press the push button once to bring
up the ERV cfm screen. Turn the knob clockwise to increase or
counterclockwise to decrease the amount of outside air coming
into the building. See Fig. 17. The exhaust airflow will auto-
matically adjust to equal the supply airflow. Press the button
again to return to the main screen. Replace the user control
cover.

Press the push button again to bring up the exhaust air offset
screen. A negative exhaust air offset would equate to a smaller
amount of air being exhausted from the building when com-
pared to the outside air being supplied to the building. Adjust
the knob clockwise to increase and counterclockwise to de-
crease the exhaust offset cfm level. See Fig. 19. Press the
