    Jandy rs temperature sensor

    Does anyone know is there an aftermarket temp sensor replacement for part# 7786. This is a 50' sensor for air/water/solar by Jandy? Thanks

    I haven't seen any.

    A word of caution: When working with gas and electrical you might want to consider a licensed contractor. Consider the value of your life and others around you.

    I believe all temp sensors are a standard 10k ohm thermistor and you can add as much wire to it as you want. You can use a Pentair sensor. And probably any other brand.

    Edit: see post below for further information.

    I just ordered one off of Amazon. I think I searched for Pool temperature sensor or something similar. There are a bunch. The main thing is to make sure the one you order is curved to match the pipe.

    Re: Jandy rs temperature sensor

    Pooldv, you are incorrect they tend to all be 10K sensors, but some have different curves so while they all read 10Kohms at 77 degrees F, the farther the temperature is away from that the more they may read wrong. This can be a big problem when it comes to freeze protection as it can shift the readout temperature by about 15-20 degrees one way or the other depending on which curve the individual product expects.


    p.s. this is usually a minor issue if dealing with swim temperature measurements as the difference is only a degree or two at typical 85-90 degree swim temperatures.
