@jtp10181 , the driver works perfectly...awesome work sir 
I tested out the Zen54 Zooz zWave 0-10V dimmer on an AC Infinity 4" CloudLine EC fan and it works a treat. Here is how it is wired. The Zooz dimmer is small enough to fit into the Cloudline Fan housing if you remove a bit of the corner bracing plastic inside the housing.
If connecting a dumb switch to toggle the fan on/off you would connect the blue wire (SW) from the relay to one side of the switch (instead of directly to ground as I have it shown), and connect the other side of the switch back to the grey (ground) wire.
NOTE, the ground leads from the Zen54 should go to the AC Infinity black, not the white as shown!!

The Zen54 dimmer does a better job with these fans with respect to voltages, particularly at the the lower speeds where granularity under 1 volt makes a difference on finer fan speed control.
