Oh, one other thing..
If I want to dim pot lighting, would I run into the same issue with the Ws12a? I just noticed the WS13a doesn't dim.. *sigh* so confused.. I need
- to control low voltage track and Pot lighting
- Dimming capability
I did notice there is an X10 pro version XPDI3, that is rated for everything (including low voltage), and dims. Will this work with the TM751 Transceiver?
The XPDI3 should work for an inductive load (i.e transformers, ceiling fans, etc) so if your low voltage track lights use a transformer, you should be fine. If the track lights use a switching power supply, the XPDI3 will work if the track light instructions say the track can be dimmed. My guess is; because of your noise problem, you do have a switching supply for the track.
The WS13 will also work for the track lights but you will not have dimming. Both the WS13 and the XPDI3 requires a neutral line.
Assuming your "pot" lights (high hats?) use 120V incandescent bulbs, the WS12 or a WS467 (both are two wire switches which do not require a neutral) will work. They will not work with CFLs or LED bulbs as they draw their operational power through the incandescent bulb's filament. Neither LEDs nor CFLs pass this power when in the OFF state.
Noise can be filtered by X10 noise filters and many times noise can be overridden with a high output repeater such as the XTB IIR. If you intend on expanding your X10 system through out the house, a repeater is a worth while investment.
