Any chance of neighbouring RF interference. Can the security feature be manually overridden. Maybe you could reset the MT14 to clear any possible conflicts.
thanks Peter A
SUre, I guess that's possible, but can RF cause an ON signal to appear? I do have a list, it's not extensive - 2 controllers (mt14 and CR13a palm pad).
I will try the isolations of the MT14 and the transceiver suggested above.
I just learned about the of the security feature on the mT14 or even where it's at. The word security, however, is not displayed on the screen,.
Quote from the MT14a sales blurb..............................The possibilities are limitless with this intelligent little timer and your array of X10 appliance & light modules.
You can even select the "security" mode and have lights turn on and off at different times of the day to simulate an occupied home when you are away.The fact that you have both RF and PLC in the same environment it opens up possible conflicts,Not sure if a neighbour's setup would be relevant to you but if your neighbour was using RF switching equipment on the same House Code as yourself his RF control could well be affecting yours. In fact with the proliferation of cheap RF electronics anything operating on the same band as your RF could cause interference.
A solution to this as mentioned above is to change your House Code.As you have two remotes listed you must have a transceiver plugged in to use them,Remove the transceiver from the power outlet and do your tests again. Finally, and highly unlikely make sure the buttons on your remotes are not pressed in the down position. possibly worn or something causing them to stick or something lying on top of them or someone sitting on them at that time of the day
Just remove the batteries to check that one.
