The following menu items allow the curtain to open proportionately to fans set up for proportional control. You must
use a static pressure sensor (even if you don’t plan on using one with the controller) to set up the curtain openings
for each stage of fan ventilation. Measure the static pressure while one fan group is running and adjust the curtain
opening until the static pressure is at the correct level. Record the curtain opening size. Next, measure the static
pressure while two fan groups are running and adjust the curtain opening until the static pressure is at the correct
level. Repeat the process until all of the fan groups are running.
Side Curtain Settings - continued
Stop Sooner
The curtain immediately stops opening or closing when the temperature returns to between the Open Temp and
Close Temp.
Abort Pause Time
The controller aborts the open or close pause time if the opposite movement temperature is reached during the
pause time. This reduces drastic temperature changes inside the building especially in winter when rapid cooling
can occur.
Skip a Movement (double the pause time)
Natural Mode Operation
There are three conditions that can cause natural curtains to react differently than described above.
Proportional Control (Tunnel Modes Only)
