Go Control Dimmer Module PD300z

Anyone used this before? I’m talking about the z-wave PD300z-2. I’m trying to use it with some string lights out on my screened porch. I can get it to pair but it won’t do much more than that. It paired as a z-wave dimmer switch generic. I’ve tried changing the device type to other ones that seem to fit but again those do nothing. I can’t seem to find a custom one for this device. Anyone have any advice or direction for me? Thanks for any help.


It’s a pretty standard Z wave dimmer module, but note that it is only spec’d to operate with incandescent lights. It won’t work with fluorescents or LEDs. And it requires at least a 20 W minimum load. What’s the brand and model of your light string?


300 W, for incandescent lamps only.
NOTE: A minimum of 20 watt load is recommended for the “Load Sense” feature and dimming capabilities of this product to operate properly.

Hi JD,
Thanks for the quick reply. Here are the lights I’m using. I have two sets plugged in together
Deneve Globe String Lights with G40 Bulbs (25ft.) - Connectable Outdoor Garden Party Patio Bistro Market Cafe Hanging Umbrella Lamp Backyard Lights 10 https://www.amazon.com/dp/B00TZRKE3M/ref=cm_sw_r_cp_apip_qcLyijLVgXDfg

They are 125w each and yes incandescent bulbs.

Nice lights!

One string should work fine with the gocontrol module, I’m not sure what happens when they are joined together.

Have you tried using it with just one string?

Thanks! Definitely cheaper than anything I could find at target and other places. They seem good so far. Both strings put it at 250w which is still under the 300w max so I don’t think it would make a difference but regardless it is showing up as unavailable now anyway and I can’t seem to get it fixed. Ugh

Have you run a zwave repair to see if that makes any difference?

Oh, the reason I suggested trying it with just one string is that particular dimmer module has a current sensing feature and I’m not sure that particular feature will work correctly if the string has been extended. Mostly it’s just something to try.

Ok cool. I’ll definitely give it a try with one string in the morning. I’m unfamiliar with a z wave repair. How do I do that?

One string didn’t have an effect unfortunately

OK. I guess my next suggestion would be to just try the dimmer module with a regular plug in lamp and see if that works. If not, it may just be a bad device, it happens. :disappointed_relieved:

Sending it back and getting a new one. Hoping it was just a defective device.
