I'm having an issue with a newly installed Raypak digital propane heater (406btu) that replaced an old Pentair model. Unit installed last week by company recommended on Rheem site (not on Raypak which I found out today) as I wanted to ensure the year warranty was honored. Issue is the heater reads about 6-8 degrees hotter than actual pool/spa temp. I have a manual thermometer in spa and Jandy temp sensor inline with pool automation that gives temp readout. Both manual and inline temp read the same. Installer replaced the inline temp sensor yesterday, but this made it worse (meaning now a 6-7 pt differential vs previous 5-6F difference). Called Raypak to file warranty claim at advice of installer. After 45 min wait, got info conveying a different warranty station from the one I used to install (which surprised to hear different than Rheem as they are now same company). They then forwarded me over to tech support. Told it could be faulty temp sensor, board, or some type of "clog in uniform governor" causing heat sensor to read higher? Who knows....but frustrated with this experience as Raypak unit thus far has been a big disappointment.
Temp readings taken were:
- pool temp 56F, manual thermometer 56F, Raypak unit 62F (no heat)
- pool 84, manual therm 85, Raypak 91F (heating in Remote mode)
- pool 90, manual 90, Raypak 98F
We did set max setpoints for pool and spa to 107 per manual, but at around 99F, the unit shuts off the propane with "no demand". Upon inspection, the Raypak reads 107F as water temp, while manual and inline readings read 99. So I can get it to 99F with no issue. Of note, upon first firing of heater, I did get a "high temp limit 2" where water reading on Raypak listed 102F, while spa was only at 97F. Hi limit fault has not been encountered again. I did have some luck with getting it slightly above 100F when I took it out of Remote mode and manually heated spa. But only to 100 or 101. Anything else to look for or that I should convey to service tech? Anyone experience this kind of water temp calibration issue?
