TM751 fixed Phase problem.
« on: June 22, 2008, 07:36:26 AM »

It was too easy, and too cheap.  Turns out I do have a phase issue in this townhouse - Curiously, troubleshooting while the 220v clothes dryer didn't reveal it?

I've been fortunate that most of the locations I've wanted modules are all on the same phase.  But there was one in the garage, and one in the house that wouldn't work.  I solved the garage problem (SuperSocket) by putting a TM751 in the bottom and setting it to the same HC as the SS.  Turns out, if I address the other non-working modules to the garage's HC, they work also!

Of course, I have to have AHP send RF commands, but hey - it works!

Crap!  I just realized a paradox  (not uncommon with X10  ;D)  - In the garage, I have a standard floodlight (D5) plugged into the upper socket of the Supersocket, and the TM751 in the lower socket HC=D.

If I use a palmpad, the floodlight responds to D5's On/Off.   And it responds to macros from AHP.  If I unplug the TM751, D5 responds to NOTHING.  However AHP is sending PLC's not RF to D5 - Why do PLC's work?  My newest lamp module in a used-to-be-non-working location (D8) now works, but only on RF, not PLC's, and if I unplug the TM751, it doesn't work at all.

Don't ya just love it!!!! :)%

May also have been just a distance issue or even both the distance and phase.
If your Townhouse is in a community setting. The power company may have supplied the complex with three phase Wye connected. Each unit maybe fed from two of the three phases and then you would have closer to 208 volts on the higher power devices.

Actually if you have the TM751 configured correctly, in AHP as a Transceiver(RF), it does send RF to that HC! ;)

Whoaaaaaa!   :o

Huh...what???  I am really feeling stoopid on this one.   I can't figure out what you mean.  I (just now) added the TM751 (from the Appliances module set) and addressed it as "D".  O.k., if I plug something into it AHP will turn it off & on - but what do you mean it (the TM751?) sends RF to that HC?

Sorry for the confusion!
The TM751 only sends out PLC. It is AHP that sends RF out to the TM751s HC automatic if the TM751 is configured right!
Since you didn't have the TM751 configured in AHP your findings are even more puzzling ::)
