I seem to have a Whole House Fan to GE Smart Fan Control, Z-Wave, In-Wall, 12730 wiring issue, or perhaps the Z-Wave device isn’t suited to run the whole house fan.
This is the Z-Wave device:
This is (or is at least very close to) the whole house fan:
The fan was originally connected to a High / Low switch (where the middle position = OFF), and worked fine. I replaced the High/Low switch with a GE Smart Fan Control, Z-Wave, In-Wall, 12730. There were separate wires to Low and High connecting to the original paddle switch. I only connected the “High” wire to the Z-Wave Smart Fan Control, and left the “Low” wire unconnected, as I only really need to turn the device on high. If it can be wired so the variable speed is an option, great, but if not, at least on/off at high setting.
The way it is currently wired, it used to start up, and seemed to work for the first <1/2 dozen times. Now, it turns on, you can hear the motor start, but it never gets enough power to even open the louvers.
I read other posts here where people used a Aeon Labs DSC18103-ZWUS behind a manual wall switch. I would still be confused as to proper wiring in that case.
Any help would be greatly appreciated.
