Enter the area of the measurement point in square feet.
The input value must be in the range from 1 to 999.9 square feet. Factory default is
1 square foot.
Sensor Flow Coeff. --
Enter the Sensor Flow Coefficient (SFC) for the type of
differential pressure generating device being used. Following is a list a standard
Tek-Air products and their respective SFC;
Generic Pitot
1.00
TFP-5000 or 6000
0.754
TPS-6000
0.624
IAQ-TEK Probe
0.762 (Factory Default)
Altitude --
Enter the altitude in feet above or below sea level for the location of the
probe. Default is 0 ft.
Low Flow Alarm Stpt --
Enter the desired value for the Low Flow Alarm set point in
CFM. Default is 0 CFM.
Analog Out Flow FS --
Enter the full-scale range in CFM for the analog output
scaling. Default is 20,000 CFM.
Alarm Delay Period --
Several of the IAQ-TEK alarm conditions have their initiation
inhibited for a delay period. This period is utilized to create a delay between the
actual occurrence of an alarm and the reporting of the alarm either at the display,
through the contact output, the digital outputs, or through communications. The
Alarm Delay Period is adjustable between 5 and 60 seconds. The default time is 20
seconds. The IAQ-TEK alarms are non-latching type, meaning that the alarm will
automatically clear when the alarm condition clears.
