This is a Jandy Pro Series salt, temperature and flow sensor for Program B. I had been using this sensor for a couple of years with no problems in Program A but then started getting "no flow" in the display which means control board does not send power to the chlorinator.
My control board is for Program A only but the sensor indicator module automatically goes to Program B so my control board will no longer work with it.
The sensor displays salt , temperature but I have no way to test it since my control board is for Program A. if you have a Program B control board it should also display flow in addition to salt and temperature. buyer responsible for pickup
