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

1 Answer

The display on the Jandy RS8 says "AIR TEMP SHORT" The sensor is reading the same resistance as the water sensor, (interchangeable) When reading resistance across pin 5&6 it is not the same as reading pin 7&8? Is it a bad board?

If you replace the sensor and get the same code,there is only one option before replacing the board...This only works on a board with one (4 pin ) red connector terminal. If you have two it won't work. On the back of the board, directly behind the "air temp" wire terminals, there is a small black diode with a silver stripe.This is a redundant circuit and isn't necessary. AFTER you turn off the power to the board, you can cut this diode off with some dykes.

New heater was left dry for 4 weeks while spa pump was replaced. turned back on with error code Fault-shorted H20 Sensor. is it truly in need of replacement or can it be cleaned after sitting and rusting?

You can put an ohm meter on the two wires of the temp sensor and see how much resistance you get. I can't find the chart right now but you should read about 15,000 ohms at a water temp of 88 degrees. Resistance drops as temp rises. A "short" will give you the same result as just holding the two test leads together.

Having the heater idle for a few weeks should not have affected anything. The temp sensor isn't too hard to change yourself if needed.

This code menad that the water temperature sensor has gone bad. These will cost around $60-80 retail, unless you buy Jandy OEM, then you will be paying well over a $100.00. But you can also use a Jandy, Goldline, or Pentair sensor and it is a fairly simple repair.

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.
