First, as a preliminary comment, I am impressed with the level of sophistication of some of the posters here. You guys really know your stuff.
To answer your questions:
1) No, the timer and pump are on different circuits. I purchased a variable speed pump (the Pentair) that is wired directly to the 220 V power without any timer between. The pump itself has its own timer. Thus, I no longer need the 1353ME timer to run the pump. However, I do need the timer to control an actuator. Both items are connected to two different 220 V breakers.
I think it well help if I explain my setup and what I am trying to achieve. You see, I have two inputs into the pump, coming from the skimmer and a pool cleaner, controlled by a three way valve. To save money, I want to run the pool cleaner for about an hour a day at 25 gal/min, then turn the valve with the actuator and run the pump at lower output to take advantage of the cost savings. To do this, I will have to synchronize the 1353 timer to turn the actuator and the Pentair pump to change the pump output/ speed.
2) FYI the timer did turn on my old pump correctly. When I test it now, it will open and close the circuit as it should. This aspect of the timer works just fine. But the story does not end here !!!
3) However, the timer will NOT turn off the P4243ME. In fact, when you test terminals 3 and 4 with a voltmeter, turning Circuit 1 on and off, there is never any interuption of the power, stays at 220V. Same for circuit 2 (terminals 5 and 6) and circuit 3 (terminals 7 and 8), as the same thing occurs.
3) I have the jumpers on the P4243 in the right position.
Confusing as heck, isn't it? However, I think (and hope) I have worked this out. I have an older version of the P1353 timer that apparently can't control this type of valve/pump switch. Remember, the power input to the transformer of the 4243ME and also the timer are derived from the same circuit. However, if the timer was working properly, it should be able to "segregate" the power input to the 4243 transformaer from the black/white switching wires of the 4243ME that are connected to the same input from the breaker (i.e. the two limbs of the 220 V input from the breaker are connected to terminals 1 and 2, the red wire from the 4243 transformer and a black/white switching wire are connected to terminal 1, there is a jumper from termional 2 to terminal 3, and the other black/white wire is connected to terminal 4).
Apparently this older model can't do this. (I'm sure there is a more articulate way to explain this, but best I can do). You statement "There is nothing wrong with P1353ME if it opens and closes circuits." is actually not correct here.
Sorry for this difficult explanation but I am not an electrician. Intermatics is sending me a new P1353 that should remedy this problem. I had hoped that maybe someone on the forum had experienced this problem to save me a lot of time and hassle that it took to elucidate the above.
When I get the new 1353 timer and set it up, I'll post my results !!!
