wiring of switches & pairing

Cyril Crook May 02, 2014 01:34PM EDT

getting zwave dongle to pair with switch. in a 2 wire light switch how do you wire a lsm-15?

It seems I can get dongle to do as it says with hsm100-3 and door lock which have buttons to push. When doing a switch do you just turn the switch on or off?

The LSM-15 is wired in the same fashion as a conventional digital switch – it requires a minimum of 3 wires to operate:

Black – represents the line input, 120VAC
White – represents the neutral
Blue – represents the load (switch leg)

The switch also has a green wire which serves as the ground. While there is a yellow wire present, it is not needed and should be cut and capped with either electrical tape or a wire nut.

In the case of a 3-way or 4-way circuit, traveler wires are not used when building an Evolve network. Instead, an LSM-15 may be used in conjunction with an LTM-5 to create a wireless, “virtual” 3-way. See LTM-5 for further details.

Ensure the LSM-15 is wired correctly. There is a small LED on the device, which illuminates when the circuit is OFF. To include the node in your network, double tap the light switch up or down while in inclusion mode.

To remove the module from your network the process is the same. Double tap either up or down and the device will be removed from the network.

The dimmer I'm replacing only has a ground, neutral and hot wire. Similarly, the outlet only has a ground, neutral and hot wire. To which wire do I connect the blue load wire?

On closer examination, my original dimmer only has two black wires and a ground: One black wire that attaches to the hot and the other to the load. There is no neutral. Will I not be able to use the LRM-AS dimmer?

Unfortunately, you need to have a neutral to use our switch (and most z-wave switches). I have the same problem at my house, the power goes through the light, then two hots to the switch. If you check out this diagram, you can see how it’s setup.

I would double check the back of the gang box for the switch. Sometimes there is a third wire tucked back which would likely be your neutral. If the house is old enough however, it is possible to not have a neutral return. If that’s the case, you won’t be able to use the switch.
