Replacing an Aqualink with an IntelliCenter

The only thing that might be different (but probably isn't) is the polarity of the voltage to drive the LED.

Turn the SPA on (which should light the LED) and then check the voltage between pins 1 & 2.

On the Jandy controls the "common" black wire on pin2 is at ~+10.5V.

Thanks. I will check that.

This is the Pentair IS-4 wiring....



So the wire color mapping is...

	JANDY	PENTAIR
COMMON	BLACK	BLACK
LED	RED	ORANGE
1	GREEN	RED
2	WHITE	YELLOW
3	BROWN	GREEN
4	BLUE	BLUE

Yes that is correct. And on the Jandy system the Black (common) wire is positive relative to the Red LED wire when the LED is on. (If you are old enough to remember cars with "Positive Ground" this is similar).

Well I am happy to report that the Jandy Spa Side remote works on an IntelliCenter. The four buttons control whatever circuits you set it up for.

I did not connect the red/orange wire for the LED. I tried measuring voltage on the black and orange screws when in SPA mode and got nothing. I did not want to risk the circuitry so I left it unconnected.

I am very happy I did not have to spend hundreds on a Pentair IS-4 that is hugely overpriced and go through the effort of pulling wires.

Thanks to @flynwill for showing me enough to get me comfortable giving it a try. I have been thinking for a while this should work.

Allen,

I though the light was an indication that the heater was on??? But, I don't have a spa nor an iS4...

Thanks,

Jim R.

On the Jandy Aqualink the LED is solid on when the spa is on and then changes to blinking when the spa heat is on.

I was wondering if the LED on the Pentair IS-4 only lights with spa heat on. Next time I am in the panel I will see if there is voltage with that condition.
