[color=#353c41]I got a ten year old used Aquaterra hot tub recently. I set the temperature to 90F, thinking I’d raise it before I use it every couple of days, but the temperature always hovers around 95-96F. -- I don't think it's a bad temp sensor, because a separate floating digital thermometer shows the same temp. -- The temp setting is not drifting. It stays at 90F. -- It can't be the ambient temperature: it’s been 40F outside at night and 60F during the day. -- I don't think it's extra heat from an overly active filter cycle. It's set to "F1" (1 hour per day). I can hear the motor turn on regularly. I haven't timed it, but if I had to guess, I'd say it's turning on roughly every hour, for about 3 minutes each. What is making the tub heat the water hotter than the set temperature? Any ideas? Thank you.[/color]

Hopefully this is an easy question for an installer. I have an older thermospas swim spa. I have upgraded the spa controller to a bp2000g1 balboa and have installed a tp900 topside. It is set to mode 7. (2spd-1spd-1spd-1spd). All pumps are visible in priming mode and work correctly. Once out of priming mode, pumps 3 and 4 disappear. They are not in the “spa” tab where pump 1,2 and the light are controllable. Thoughts? thanks in advance, matt
