SOURCE: Have a 3.5 year old Jandy Aqualink RS 4 --- the

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
adam

SOURCE: Have an Aqualink RS4 and the freezing protection

There is a freeze guard sensor that is attached to the RS4 system. Over time, these sensors do fail. The "field test" for our technicians is to take the sensor (see picture below) and place the coils in a cup of ice water. The sensor "should" turn the pump on and leave the pump on until the coils are removed from the ice water and warm back up above their setting. You also need to make sure that the temperature sensors on your panel are reading correctly. Since the Aqualink has air and water temperature sensors, there is a possibility that the temp sensors are incorrectly reading the temperatures and conflicting with your freeze guard. Check your pool water with a standard pool thermometer and match that temperature against your panel reading and then do the same with the air temperature. More than likely, the freeze guard sensor has failed and needs to be replaced. We see this commonly at the beginning of each year as the temperatures change. Its always a good maintenance item to check your sensor (ideally 1 time a week) once a month with the simple ice water test listed above.
As far as changing these sensors, they are relatively easy to replace. The contacts are 2 wires that plug directly into the RS4 board.
The freeze protection replacement should run you anywhere from $130 - $180 though the MSRP is much higher: Part number:

SOURCE: On Jandy Aqualink RS display it says 6700 Rev C

6700 REV C is usually the control boards and in rare cases the wiring between the two. Here is a post to troubleshoot http://goo.gl/4Hp7k. It also points to www.fixyourboard.com. Bottom line, don't buy new, get them fixed.

I've got a Jandy PDA, PS4. How can I set the Freeze Protect below 34 degrees?


It doesn't set below the freezing point. That is exactly the point of the minimum setting of 34 degrees - just above the freeze point. If it would set below that temperature it would freeze.

Connecting problems


Installation
The scripts communicate with the Jandy system through a USB Serial Adaptor (e.g. the Keyspan USA-19HS USB Serial Adapter) connected to the Jandy Aqualink RS Serial Adaptor.

In order to use these scripts with SerialX, you will need to separately download and install SerialX as a Scripting Addition. As currently written, you will also need to determine the exact name of your serial connection and edit the following statement in both scripts:

property SerialConnectionName : "/dev/cu.USA19H47P1.1" -- Replace "dev/cu.USA19H47P1.1" with the name of your USB Serial Adaptor.

After editing, drag the Jandy Aqualink attachment script into the folder: /Library/Application Support/Perceptive Automation/Indigo 4/Scripts/Attachments
and the Jandy Aqualink background sync script into the folder: /Library/Application Support/Perceptive Automation/Indigo 4/Scripts/Background Tasks
Initiating use of the background script is typically accomplished by establishing a Trigger Action that activates on Indigo Server restart.

Usage
Assumes a Jandy Aqualink RS-4 or RS-8 Pool/Spa combination with auxiliary 1 set for pool light and auxiliary 2 set for spa light.

Unlike the previous version, the background script will now automatically execute periodically after being initiated (typically with a Trigger Action that activates on Indigo startup), will create variables as needed, and will update the status of those variables. By default the updates occur every 30 sec for most items using a single "#LEDS?" command, and every 30 min for the temperatures, with error detection if something does not update correctly. If the Spa is heating, temperature updates default to every 2 min. Variables created include AirTemp, ErrorFree, NextTempUpdate, PoolHeatEna, PoolHeatOn, PoolLightOn, PoolPumpOn, PoolSetPoint, PoolStateOn, PoolTemp, SpaHeatEna, SpaHeatOn, SpaLightOn, SpaSetPoint, SpaStateOn, SpaTemp.

Is it common for the blower motor to come on during freeze protection?


No. The program for the various pool systems has been incorrectly set.

Aqualink RS4 Water temperature reads 120 - obviously wrong.


No but this sensor is easy to replace. Just pull the sensor from the pipe by loosening the staniless steel clamp that holds it in the pipe. Then follow the wire back into the Aqualink box and unplug. Get a new one at your local store and replace. It's a common problem and you should be able to do it with ease.
