• Min Ventilation Heat Setpoint: The minimum airflow that the damper tries to achieve<br />
when heating (overrides minimum ventilation setpoint during heating only). To enable<br />
this setpoint, one of the outputs must be set to “Duct Heater” (see p.20).<br />
Units MIN MAX Default<br />
Cubic feet per<br />
minute (cfm)<br />
0 2000 120<br />
2.1.7.2 Duct Setup<br />
• Duct Diameter: The diameter of the duct in which the flow sensor is installed.<br />
Units MIN MAX Default<br />
Inches 0 20 8<br />
• K Factor: Multiplication factor induced by the airflow sensor (specified by the<br />
manufacturer).<br />
Units MIN MAX Default<br />
N/A 1 300 2.39<br />
• Sensor Type: The type of flow sensor used.<br />
• Low Velocity: Up to 1200 fpm.<br />
• High Velocity: Up to 2200 fpm.<br />
2.1.7.3 Sensitivity<br />
• Sensor Differential: The airflow must change by half of this amount before the damper<br />
will attempt to compensate for the change in airflow.<br />
Units MIN MAX Default<br />
Cubic feet per<br />
minute (cfm)<br />
0 1000 40<br />
• Damper Speed: The speed at which the damper will move to reach the desired airflow.<br />
Slow this down for increased stability. 1=slow, 5=fast (3 is the default).<br />
