I thought this would be an easy switch over but my brain is fried.
I had a single speed max-e-pro and replaced it with a 2 speed of the same model P6RA6YF-206L. I have a Aqua Rite SWG and a Intermatic T104R.
1. I thought the new pump would have a toggle for high and low speed, but it doesn't.
2. The pump wiring instructions are crappy, combining 115v and 230v in the same diagram. However, I think it deals with four terminals:
A, L2, L1 and G. L2 gets line voltage all the time and the other line switched between A (low speed) and L1 (high speed).
3. The diagram shows the switching between A and L1 is done but a SPDT switch (which they don't mention whether it's included or not).
4. The Intermatic seems to be a SPDT switch, in that it seems to cut both line voltage wires when in the off position (so no power is sent to the existing motor). The screws are numbered 1,2,3,4 and it seems that line comes in on 1 and 3 and goes out on 2 and 4.
5. There is one weird thing on the pump. With the end cap removed, there seems to be plastic caps covering a set of electrical contacts, in a "Y" configuration. The old pump motor has the same contact configuration but there aren't any plastic caps. The look like they are something for shipping but the installation manual doesn't show the contacts, much less the plastic caps.
My plan was to run the SWG whether the pump is on high speed or low. If that's too tricky I'd just do it with low speed. It seems the easier thing would be to get a SPDT switch that switches the one line voltage wire from high speed to low speed. I don't see any need for a center off position because I can turn the motor off at the breaker box (which is located at the timer). If so, can someone point me to an inexpensive one? I've seen some toggle switches but they aren't enclosed at all. Levitron makes a lightswitch looking thing, but it's $50. Apparently intermatic has a T106 for use with a 2 speed, but that's $125.
Once I find this SPDT switch, I still need some help on wiring it. Breaker to Intermatic to SPDT to pump - maybe not in that order. And then where should the SWG connect? I understand that there might be power running all the time to the pump, but that's okay since I'll cut the breaker whenever I work on it (assuming having one line voltage line hooked up all the time doesn't hurt anything).
