Raypak heat pump(8350TI) showing 58 degrees when it is 85 degrees in pool?

[gullzway]

My raypak 6350TI heat pump just started showing that the water temp is 58 degrees, when it has been set to 85 all summer. I installed it in May and have had no problems until now. I shut the breaker off for about 10 minutes, but it goes right back to reading 58 degrees when powered back on. The water is definitely 85 degrees, according to several thermometers and me swimming in it.

Wondering if there is something else I can reset, or if the temp probes can go bad on these that quick. Any help is appreciated.

Are you sure you're not reading it upside-down?

Temp probe is likely gone bad. If you just installed it this year I would think it would be replaced under warranty.

Solved: I contacted Raypak and they sent me instructions for reprogramming the main digital board, included in the main board replacement kit.
I did this and it is working again, showing 86°.

Though I cannot find this information mentioned anywhere online, including Raypaks website.

You won't find all information on things like reprogramming instructions. Most times they only provide that info to techs.

I just had to do this again today. Pool has been open 3 weeks with the heater set at 85 running great. Checked it today and it was reading 56. I dug up the Raypak email from last year and reprogrammed it and it's working fine again. Is this very uncommon?
Here are the instructions in case anyone else has this problem.
