For some reason the temperature sensor on my Paddock Aquatouch no longer reads the correct temperature. It thinks my pool water temperature is in the range of 30F despite the fact that it is actually about 85F. As a result, it keeps needlessly turning on my pump filter every 5 minutes! How can I disable this? I've Googled for my control system model but it is pretty old and all the results show newer models which have controls mine doesn't. I assume there's a temp sensor somewhere I can disable it from listening to maybe? How?
By playing around a bit with the buttons in all the combinations I could think of I did find that when I press "Program, Enter" I get the following message:
Press devices to activate for freeze protection - press enter when finished
Unfortunately, just hitting enter informed me that the filter pump was protected. I tried adding and removing a couple other pumps, but while I was able to add them, I wasn't able to remove them! When I hit enter it says:
Devices allocated to freeze protection are: Pump Aux7 Pool Htr Spa Htr Freeze protection is enabled
Implying there is a way to disable it. But I haven't been able to find a combination to do that.
The circuit board (A Jandy Aqua Link 5574C) is shown here. I have circled in red where the temperature sensor wires appear to connect. However, there are 4 wires instead of the expected two: green, yellow, red and black.
I have ohmed out these 4 wires with no power:
black and red: 1.2 ohms
black and green: 1.5k ohms
yellow and green: 1.5k ohms
Update: After I closed up the box and turned power back on after taking the bottom picture, the temperature reading went as high as 84F before dropping first to 75F and then 49F.
