Ok, tech came out, tossed three thermometers into the spa. Spa's holding temp at 103-104, but display is reading 98. He says the "intake" water is the temp on the display. I say BS, fix the display. He doesn't know if he can, he will "call the manufacturer". I also asked him to leave me one of those thermometers so I can check it next time I'm in. Also got the regular yadda yadda about how the temp will drop since it's so cold outside - yes, I know this. Any other HS owners have this issue? I think it's ridiculous that I can't/don't know the spa temp via the friggin' display (which reflects an avg 5 deg difference!). Thx in advance.
