Control System Notes
This ventilation package is capable of being set to
meet the current ASHRAE specifications for minimum
occupied airflow rates.
On/Off Operation
Energizing the A terminal in the low voltage connection
box during occupied conditions will drive the fresh
air damper to the fixed position selected as shown in
Figure 14 on page 7.
Blade Adjustment for Desired
Ventilator Air
The amount of ventilation air supplied by the
commercial room ventilator is dependant on four
factors.
1. Return air duct static pressure drop.
2. Supply air duct static pressure drop.
3. Indoor blower motor speed.
4. Damper blade open position setting.
Refer to the appropriate graph on pages 9 and 10 to
determine the blade setting necessary to achieve the
ventilation air required.
