How does one disable the local sense functionality of the X10 XPR-W receptacle?
-
The XPR-W has no local functionality. It's a duplex X10 outlet. If you plug a pair of lights into it and turn either lamp on by it's switch, if the XPR-W has been installed in AHP, AHP will not show the XPR-W as on.
-
For reasons X10Pro [X10's is the same way] may know. The XPR Wall receptacle has a Local Control Sensing circuit in it. It will turn on if you cycle the loads local switch from on to off and back to on. As Dan said it is not two way and if locally turned on it will not be known to other controllers. I have not seen any modifications for disabling this sensing. Other than our add a 4 watt incandescent night light to the circuit, which may stop the sensing.

My idea is to control a series of outside downstream receptacles with one of these XPR-W receptacles. The idea being no outside receptacles will work as long as the XPR is off (people I don't want using these outside receptacles are doing so while I am away). This will keep me from having to do any real re-wiring while still having interior receptacles which are inside the house and on the same circuit as the outside receptacles. The problem, you might imagine, is if someone walks up and plugs a load into one of the outside receptacles or turns a load off/on which is plugged into one of the outside receptacles and kicks on the outside power anyway.
So, you mean there is none of this taking the thing apart and clipping a diode or a trace like in the case of an appliance module?
What kind of current are we trying to defeat here?
Appliance modules allegedly go after 50 mA or higher to know a load is present and below 50 mA to know if a load is not present (this is correct, isn't it?). That would require a 6 or 7 W night light load, correct?

On another note, what is the largest motor which could be run off of one of these XPR-W receptacles?

You Cannot use either a XPR-W or a SR227 to control anything that can't be plugged into it. It's a X10 controllable outlet!!!

The X10Pro XPR has a blue switched line lead; that you maybe able to tie to the downstream outlets. The X10 SR227 does not have the added switched line wire to control downstream outlets and is an X10Pro PA011. 15 Amp one outlet controlled. The XPR is a 20 Amp both outlets controlled and a controlled output to go to outlets downstream.
I have not seen any mods to disable the local control on either module. We also have seen many of the X10 and X10Pro modules being redesigned to use more readily available parts. In the process older mods don't match the present module's ::) and some new features [soft start etc] where added. ???
I have not seen the ratings for either module in the printed install manuals. Should be on the label physically on the module.

Hi,
I've managed to follow these instructions http://www.x10community.com/marko/2006/06/disabling_the_local_control_fe.html (http://www.x10community.com/marko/2006/06/disabling_the_local_control_fe.html) to disable the local control and sense current on appliance modules and SR227's but I'm stuck on the XPR-W....
Anybody had any luck managing o turn off local control and sense current with the XPR?
Thanks

http://www.x10pro.com/pro/pdf/xpr.pdf
20Amp X 120V equals 2400W. One HP is about 750W.
But what is the size of the breaker feeding this circuit?
