I did that last night and it went through the entire priming and resetting process but stayed at 95 degrees all night and through the morning

Did it used to go alot lower than that? I mean before or is this a fluke thing? Because if it is normal for it to only drop that much you should be happy. Down East is not known for being the most energy effecient. It would go down to 60 or 80 depending if it was in sleep or economy mode. I'll confirm about the thermostat later tonight (I get to work the evening shaft tonight)

I do turn it down to 80 during the week as I work long days and pretty much (unfortunately) only use it on the weekends. Also, this has not been an issue in the past where the tub would be pretty much equal with the ambient temperature and not 30-40 degree above when in either the sleep or economy mode and setting the temp at 80. You may want to consult the manual for your specific spa and see how they explain how their "sleep mode" is designed to function. Really though, if you've set the temp to be 80F, and it's actually 95 to 100F, you could have a bad thermostat in your spa. If your spa water temperatures were reaching ambient (50F?) while in sleep mode, it's not insulated very well. If it only shuts down the heating system for 6 to 8 hours, and drops from 80 to 50 even, the spa can't be very heavily insulated. If it has in fact been dropping that far in water temperature during its sleep mode, you're probably creating a higher electric bill than you need to. It's likely cheaper just to maintain a steady temperature than re-heat all that water every single morning when the spa kicks back on. Its never gotten below 60 in the sleep mode (Not clear writing on my part) I was just saying 50 since that was the outdoor temp but the spa is staying at 95-100. I will verify with a second thermometer if the water temp is the same as the spa thermostat to rule out the possible thermostat issue

I have a 2007 Down East Exeter and I went to check the levels yesterday morning and noticed the temp was at 95 degrees (temps were in the 50's overnight). The spa was set to sleep mode so should have gone a lot lower than that. I also used the spa last night (6 hours ago) and just checked and it is in sleep mode and the temp is at 100 while the out door temp is 51. Any suggestions on why it is not cooling down? Thanks
