I have an IBS-P01RS remote pool thermometer. For some reason the sensor turned to Celsius and won’t go back to Fahrenheit. I have a one-button model. When I press it for 5 seconds or 10 seconds nothing happens.

The receiver is working okay.

Any ideas how to get this to change?

Hello,  
Is the IBS-P01R-O transmitter connected to the IBS-P01R-I receiver?  
If not, please connect the IBS-P01R-O transmitter to the IBS-P01R-I receiver and then switch the temperature unit via the CF button.

Thank you. I thought I tried that. It’s back to reading Fahrenheit now. 🙂
