How to over-ride a timer using X10

[Xringer]

These directions are for programmable timers with battery backup.
The over-ride is only for turning the load off..


First you need the X10 remote transmitter.




Then you need the X10 appliance module.



Plug the timer into the X10 module and then plug the load into the timer.
Then, plug the X10 into the 120vac outlet.



Using the remote, I've just turned off the X10. At 8AM tomorrow morning, the forecast calls for rain.
I don't want moist air coming in..

So when the timer switches on at 8AM, there won't be any power to run the ventilation blower.

Anyways, I can't by-pass the timer's programming and run the blower using the remote.
For that, I have to run down to the basement and press a button on the timer.
Putting the timer manual ON mode, or Auto ON mode so it will start running the programed schedule again.


Funny story. When I first set this up, I just had the timer in the AC socket.
When I decided to add-on the X10 over-ride module, I just plugged it into the timer.

It worked okay, until I tried to turn off the blower, while the timer was off.
The timer was blocking the X10 signals (& AC power), so the X10 failed to operate!
So, now they are plugged in, in the correct order! The X10 now sees every command..


This is going to be so much simpler when I get the micro controller running things..
It will check the temperature and humidity and send the right X10 command..
Might even get rid of the timer..
