Can anyone help out with this problem? I have the Monster AVL300 remote and have a 3-way (actually 4-way) set of light switches in a room. I purchased an Intermatic 3-way Z-Wave dimmer switch on Amazon and was told that I could simply swap out one of my existing 3-way switches for the dimmer.
After I do that, the dimmer works. I can increase and dim the lights. The problem is that the lights can ONLY be turned on from the new Intermatic dimmer, not from any of my other switches. So basically all of my other switches do nothing but turn lights off (i.e., rather than being able to turn them on).
Not sure about Z-wave, but similar switches usually come with auxiliary switches designed to work with the primary in some kind of set or kit. Without those, I don't think it will work. If that's not the case, then make sure your hot and travelers aren't mixed up.
Carefully read the instructions and try to understand Adidas' post. In my case I was able to use the existing 3-way switch as the accessory switch so there isn't anything you will need to buy. However, I'm not sure about a 4-way connection.
With Z-Wave, it's a mixed bag. For 3-way use, most dimmers require a specialized companion switch; the exception would be the Intermatic (or Wayne Dalton) HA14 and the Intermatic HA20. These are designed to be used with standard 3-way switches with traveler wires. Note: The older Intermatic HA06 dimmer is not designed for this type of 3-way use.
One alternative to consider: If your 3-way locations are powered with hot and neutral wires, you can install a Z-Wave controller at those locations and simply associate that with the load carrying switch. A relatively low cost option for this would be the ACT ZTW103.
