LZW-35 Blue Fan Switch Behavior

[davidwilliams]

I have just installed a LZW-35 Blue Fan switch on my fireplace fan, replacing the speed selection dimmer that was in place (Hot and load only on previous dimmer - Neutral connected for LZW-35.) I have it set up as a multi-speed/ceiling fan since I know it can be dimmed based on the previous wall switch.

I’m seeing some odd behavior. When I have the fan set to 34-66%, allegedly medium, it runs at full. When I go to 67% and higher, it gets slightly slower, but not enough that it would be considered a different speed. At 33% and below the fan barely, and I mean almost inaudibly, runs. I’m concerned the fan is not getting enough power in this setting.

Is there a way to customize the amount of power being provided for each setting since every fan will respond differently? Or is this fan incompatible?

Thanks!

Verify the fan you’re connecting to can use a ceiling fan style speed selector. Especially if the old control was one of those “dial” style speed controllers then this switch can only work in exhaust mode, not as a speed controller. You can burn up a motor using the wrong kind of controller.
