Hi all,
I am using a self contained HVAC system, but I want to control the fan separately. The unit comes with a remote control that provides two fan speeds, so I want to be able to power and control the speed of the fan. The fan motor shows the wiring diagram below:
Sorry for the blurry picture. The right side wires show GND, Vcc, and Output, which I assume is the 208V/3ph feed into it. The capacitor is a 3μF/400V. I don't know what the P and the circle with the squiggle are but hopefully one of you can tell me.
Typically, we would use a 0-10V or 4-20mA output to control the fan speed, but I'm not sure what this fan uses and I don't want to mess with it before I know for sure. Can anyone shed some light as to what I can do to control the speed?
I called the manufacturer, but didn't get too far. Either they don't know or don't want to share their proprietary information.
Thanks for the help!
