Hi guys - I have a duct fan that traditionally uses an old-school variable speed fan control like this one: http://amzn.com/B0087486N4 . When you turn this control from off to the lowest setting it runs the fan at its lowest setting, and as you increase it slowly it slowly increases the fan speed until it reaches the max.
I am looking for a Z-Wave device that will do the same thing. The GE 12730 Smart Fan Control http://amzn.com/B00PYMGVVQ will NOT work like this, because it does not really have a smooth, variable speed control. Instead all settings below a certain point are considered slow, then after that point all settings until the highest point are considered medium, and past that point all settings are considered high. So the fan only operates at slow, medium or high. Whereas I am looking to get the full variability that an old-school speed control would provide.
Does anything like this exist for Z-Wave? If not, is there some creative way to combine Z-Wave devices with old-school electronics to effectively make the same thing happen? For example Z-Wave could send one of say 5 signals to an old-school electronics project which would then sent one of 5 voltages (which are preset, but at least they are preset by me and there are 5 instead of 3 like the GE control) to the fan?
