Question about Jandy Aqualink - Rs24 One Touch Pool / Spa Combination Control System

1 Answer

Jandy Hand held reads the wrong wrong pool temperatrure

The air temp is correct the pool reads 171 but if you press the temp button on the Jandy Control panel outside it gives the correct pool temp. Solar heater won't come on hand held says enabled and spa heater won't come on it says enabled. does the panel pull its temp from a different probe or from the chlorine generator's sensor?

The chlorine generator is giving you a correct readout of your pool temp. however, your water temp sensor is bad. if you look at your filter pump, follow the pipe coming from the top of the pipe, until you see a metal clamp. withthe system off, remove the clamp and pul out the sensor from the pipe and replace with a new 10k ohm temp sensor. NOTE: Older Jandy systems used black temp sensors, the new sensor may be slightly larger. use a masonry drill bit to bevel the old hole out for the new sensor, and replace the wires.

    youll need a cordless drill and a drillbit to match the same size as the new sensor. Drill very slowly and very carefully, so you dont go through both sides of the pipe, just the top. I prefer to use masonry drill bits. There are 2 ways to rewire the sensor, the first would be to splice into the wire close to the sensor, using waterproof connectors, connect the red to the red and the black to the black. The 2nd way to rewire the new sensor in, would be to remove the front panel on the outdoor control box, then trace the wires back to their place on the green bar and replace them with a small flathead screwdriver.

SOURCE: I have Jandy RS4 system with 4-button poolside

Pull the cover off the control panel. You will probably find a button which would be accessible from outside the panel with a paper clip or pencil but is unlabeled. On the board itself by the button, in small letters it should say "reset". Push the button and see what happens.

Have a 3.5 year old Jandy Aqualink RS 4 --- the air temp is reading correctly (78 F) but the pool temp is reading (201 F). What could this issue be? Pool sensor gone bad? If so, how do I repair or replace...


It is most likely not a bad reading on the on the display.

One culprit of a false temp reading could be:
If the temperature sensor is installed after the heater and the circulation pump is clogged or failing, this would allow super heated water to reach the temperature sensor and give you that reading. However, most pool/spa heaters have a high limit switch that would shut down the heater @ 150 degrees F. So this is also unlikely.

The most reasonable answer is to replace the temperature sensor.

If you refer to page 22 in this manual http://www.jandy-downloads.com/pdfs/Allbutton_manual.pdf
you will see that the temperature sensor is installed on terminals 5 and 6.
Trace these wires. They will goto a thermowell (which holds the temperature sensor) either in the pool plumbing, or to a temperature sensor in the heater itself. Temperature sensors when in the heater are located typically above the inlet/outlet header. There will be some disassembling required to access it in this case.
If it is in the heater and you need more help, e-mail me @ adamh@newconceptchem.com

Please take the time to give me a positive rating on this post if I have helped.

Thanks

Jandy aqualin rs air temp malfunction


Check this by swapping your air sensor with your water sensor. (Just swap the plugs) if it still reads off then you may need a new board, if this reads ok then the new sensor may be bad. Good luck.
