Part # ECS0275
Water Temperature Sensor replacement Kit - ECS0275
I am ready to install the ECS0275 replacement temp sensor. It looks a straightforward job. I'm certain that the sensor to the pipe in this photo is the one that needs replaced. Can you confirm? Thanks.
That is the correct pipe where you need to place the new sensor. You will leave the original in place & tap a hole above or below the coupling.

I have the aqua cal t115 as well and the picture matches my temp sensors. My temp reading has been off the whole summer by10+ degrees. Today it shutdown with the overheat error. Assuming the temp sensor is shot. Question I have is you mention drilling a new whole for this sensor. Are there specific instructions (drill bit size) with this purchase. Or do I have to take a guess and hope I get it correct? Any help appreciated.

Use 11/32″ or 3/8″ drill bit to tap into water inlet line.

I shut off my whole system and electrical breakers. Then I opened the front panel on my heat-pump and saw the leak was coming from the temperature sensor on the heat exchanger. I shut flow to the heater off and turned the system back on, then I ordered the sensor from Inyo pools and installed it back. I turned the heater back on and it’s working just fine.

I have a AquaCal 115AHDSBPH Heater. The water temp reading kept creeping up and up, preventing the heater from turning on so I decided to try this part. If you are going to replace this part, PLEASE BE SURE TO TURN OFF THE ELECTRICAL BREAKER FOR THE HEATER BEFORE STARTING. Double check on the control panel that the unit is off. Then remove the 10 or so screws on the front plastic cover and take it off. Finding all the screws and digging the rocks out from around the bottom of my heater was the most difficult part of the whole project. Once you get the plastic off, remove the 4 screws from the metal electrical panel cover to access the part you need to replace. The main board is on the left side and there are a bunch of wires connected to terminals in a row. There is a wiring diagram on the back of the electrical panel so please confirm what I say to be sure your board is laid out the same. It should be labeled as "WATER TEMP SENSOR" or similar on the diagram. Starting from the RIGHT side, disconnect the first connection on the top and bottom which are for the water temp sensor. These two wires will lead to the sensor mounted on the inlet pipe by your right knee if you're kneeling in front of the unit. It should look just like the one you bought from Inyo Pools. If it doesn't, you might be better off to leave that one alone and drill a new hole in the inlet pipe near-by to mount your new sensor. After you remove the clamp holding the old sensor in place, pull out the old sensor. Mine made a hissing sound from the pressure built up in the system but no water came shooting out. Next replace the new sensor back into the pipe using the new hose clamp provided with the kit. Run the wires through the loom and back through the grommet like original and plug the wires back in. Often times with a sensor or switch like this it won't matter which wire is connected to which terminal. I do not know for sure if that is the case here, but I plugged one wire into each terminal and the unit is working so I left it at that. Replace the covers, turn on the breaker and you should be back in business.
