i,
The input to your EasyTouch looks to be 240 Volts AC..
And I suspect that the very bottom breaker feeds your IntelliFlo pump..
But it does not appear to me that you have any 240 volt breakers.. I am not sure about the bottom two (4) breakers, as I have not seen that style before.. I suspect they feed the IntelliFlo, but they are only 15 amps and normally the IntelliFlo is wired to a 20 amp breaker.
Can you tell if the 2nd conduit from the left goes to the IntelliFlo??
In general, if you have an EasyTouch system, you would need a Pentair IntelliChlor IC40 salt system, so that you could use the EasyTouch to control the SWCG and to display the salt reading from the cell.. You can use any SWCG system you want, but then the EasyTouch would only be able to turn it on or off.
Since your EasyTouch did not come with an internal SWCG power supply, you would have to buy a complete Salt system.. This would include a Power Center and the cell itself.
If you want your salt system to integrate with your EasyTouch, you will need the following..
If you don't care about the integration, then you are free to buy whatever SWCG system that floats your boat...
No matter what SWCG system you buy it will have to be connected to your pump/filter relay.. This relay in your EasyTouch is not being used now.. It will need to be connected to an input AC source (120 or 240 volts) and then the output of the relay connected to the SWCG system, which could be configured to accept either 120 or 240 volts..
Thanks,
Jim R.
