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.

Heat-Pump was Leaking

Written on 1/15/2019 by Guest

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.

Were these instructions helpful?
