I have just swapped out a single speed A.O.Smith 2HP Pool Motor for a 2 Speed Energy -Efficient A.O.Smith Pool Motor (Same HP).
The old motor had 3 terminals in back - L1 (Common) L2 and a Ground Wire.
The new 2 Speed has 4 terminals - L1 (Common) L2 (Hi Speed) "A" (Low Speed) and Ground Wire.
I suspect that I need to run an additional wire from the control panel to the "A" (Low Speed) terminal.
Problem is, I have no idea how to do that. The pump runs and water is moving, but it's constantly on High Speed, thus negating the energy efficiency. Any assistance would be gratefully accepted.
You will need a two speed time clock to really take advantage of real energy efficiency savings. Intermatic makes one that fits in place of the original t104 time clock. You will need to run an additional wire to the pump as well. You will have the ground. Then one common wire that is always hot whether or not you are on high speed or low speed. You could make this a white wire. Then a black wire for your high speed that is energized in high speed and a red wire for the low speed. It is important that the high and low speeds not be energized at the same time, otherwise you will hear a very unpleasant sound coming from the motor, and failure and shortened life of the motor will be realized.

I do not know the Sol very well, although i have heard of it. It is not common in my neck of the woods (so. california). However, most automation systems have some specific way of controlling a two speed pump. Jandy for example, probably the most popular automation system, requires the additon of a special 2-speed pump relay. Unless your comfortaable working with electricity and understanding electrical schematics, you might want to consider farming out the installation. Aqua Logic controllers, another popular controller, do not require the additon of another seperate relay, but require the controller to by wired a certain way and configured to recognize the installation of a 2 speed pump. In all instances, if you are going from a single speed to a two speed, you will need to add another high voltage connection from the controller to the pump. You should condult the installation manual that came with the Sol when you purchased it. I am not sure if that unit is still manufactured, however, you should at least be able to download an installation manual if you cannot find yours. Good Luck.

I have a Polaris Sol 1000 Control Panel, so I presume I would need some additional components for that panel?
