Sensors - Jandy AquaLink RS Troubleshooting Manual

Sensor
There is only one AquaLink RS temperature sensor. It is used for reading water, air and solar temperatures. The sensor is
described as a 10K RTD (10,000 Ohms - Resistive Temperature Detector) sensor, although the actual resistance will vary
with temperature. Below is a chart which shows how resistance changes as temperature changes.

When measuring resistance across the sensor leads you must remove the sensor from the circuit.
Either disconnect both wires from the terminal bar or remove the terminal bar from the PCB. Then, to test
the Sensor, "0" out your meter and take reading across the sensor.
If a sensor fails, the Controller display will scroll on that sensor "Shorted" (i.e., little or no resistance), or "Open"
(i.e., no continuity).
NOTE: Temperature sensors from other Jandy Control Models cannot be used with the AquaLink RS.
