Total Opening Time; Opening Display (Time / %) - Airstream ITA-6 User Manual

Total Opening Time

You must specify the exact time that is required for the actuator to reach
its maximum limit switch. The opening of the actuator will then be limited
by this opening time.
Set this parameter before
calibrating the inlets.
• Select "TOTAL OPENING TIME" using the function selector. The
time that is required to fully open the air inlet is displayed (in sec-
onds).
• Use the adjustment knob to set the total opening time to the de-
sired value.
• Proceed in similar fashion to set the total opening time on all
ITA-6 units.

Opening Display (Time / %)

The user must assign an inlet position to each ventilation stage. This posi-
tion can either be specified as a moving time of the actuator or as a per-
centage of the total run time. When the percentage method is used, the
controller converts the inlet's moving times into a percentage based on the
total run time of the inlet.
Choose the desired opening display method:
• Time value:
• %
Note that displaying the opening as a time value gives
a little more precision than the percentage display.
