To adjust the airflow ventilation rate (NO CO2
CONTROL/NON-MODULATING) , determine the "FLOW
INDEX" needed for the intake and exhaust blowers for
1.> Locate two 0-10Vdc Motor Control Boards in control panel
2.> On intake Motor Control Board, observing "GREEN STATUS
LIGHT", turn manual adjust potentiometer (with a small phillips-head
screwdriver) "CCW" to increase "FLOW INDEX" or CW to reduce
"FLOW INDEX" to match desired setting. (NOTE: After long pause,
the green status light will blink long-blinks for the "TEN COUNT" of
the "FLOW RATE INDEX", which then is immediately followed by
fast blinks which indicate the second digit. For example, a Flow
Index of 23 would be two long blinks, followed by 3 fast blinks of
