tsttm I saw another post of yours
here.
I took the time to review all your posts.From what I saw...
and correct me (please) if I am wrong. You live in an apartment, and you have one troubled module... which is due to a phase issue. Your currently looking to resolve the issue (maybe with a passive phase coupler... such as the dryer plug... except you don't have one). And your also an AHP user.
Normally... I encourage everyone to completely resolve phase issues.... but its not always the best method. You might find its cheaper, faster and easier to find a work around. One way could be the use of a
RR501.. also called a
polite transceiver. Similar to the TM751 transceiver... except it will wait and not step on other PLCs (like those from your CM15A). It also has a selection for local control switching of ether the 1 or 9 unit code... of whatever house code it is set to. By setting your CM15A to send the RF signal for that H/U code... you should do OK.
