Increasing Fan Speed
External Static Pressure
If external static pressure is too great(due to long extension of ducts, for
example), the air flow volume may drop too low at each air outlet. This
problem can be solved by increasing the fan speed using the following
procedure.
Remove the screw on the electrical component box and remove the
cover plate.
1
Adjust the DIP switch(SW05) on the main PCB to the “OFF” position.
2
Re-install the cover plate and join the removed screw.
