Sns On Display.
When I turn on the unit it will display RV1 and the temp for a couple of seconds and then display SNS and either Pool, Spa or OFF as I press the mode button. This is with the unit set to REM OFF. If I turn the unit to REM ON by holding down all three buttons for 5-7 then it just displays SNS OFF. The guide on the unit says SNS is a sensor error, but I don't know which sensor it is refering to.

I was able to download the manual from this site and found out that the SNS error refers to the temp sensor. It is the RAYPACK 009577F Temperature Senor. You can get a new one from Amazon.com for about $35. It's a pretty easy repair.
