Using analog inputs:
At .5 VDC the fan starts at the pre-set analog RPM valve (ALM1 setting in the ECM board).
At 10 VDC the fan is at the high speed analog setting (AHM1 setting in the ECM board).
From .5 VDC to 10 VDC the fan ramps linear to the maximum RPM setting (AHM1).
No start command is necessary when using 0-10 VDC input. The analog floor is .5 VDC. Any signal under that value the fan is off. That "floor value" is adjustable in the ECM board.
