Balboa Spa Controller Question
Posted 02 September 2008 - 07:50 PM
I noticed the temp was 104°F while I was explaining the spa controls.
He accidentally put the Balboa into economy mode and closed up the spa.
When I went out today for a soak I saw the temp was 108°F. The water had never before gone above 105°F.
I put the Balboa back to standard mode and its OK now, but why would the h2o get so hot if it was in economy mode, which is supposed to only adjust the temp during occasional filter cycles? I would've thought the water, if anything, would end up cooler than the set temp.
The air temp was about 75-80°F.

I have the M7 pack with the two probes.
When I saw the high temp I checked the heat LED, it was off.
After I put it into standard mode the temp started decreasing.

Pesky economy mode.

That was it. Not only did my friend manage to get the spa into economy mode, he put it on an 8-hour filter cycle.
In case anyone finds this thread while having similar issues, here's the info for getting into those menus, which are way too easy to get into and change accidentally.

The heater doesn't go on when the water temperature is 104°F or higher.
The water pump creates heat as it moves water. For filtering, the pump is supposed to be on for two hours a day, which heats the spa shell with just enough heat to push the water temperature up by a degree or so. (This added heat is a pleasant side effect while people are in the tub enjoying the jets.)
When the pump is on for eight hours at a time it produces heat for a longer period, eventually overheating the water.

But on my Vanguard, if you put your foot near the circulation pump outlet, not only do you see the ozone bubbles coming out, the water is hot!
At first I thought something was wrong and my heater was stuck on, even though the tub was maintaining temperature perfectly.
So I checked my electric meter and it was barely turning, then I cranked the temp up to turn on the heater, and yep, it started spinning like a top! So just running the circulation pump supplies that much heat. I dug through the H/S owners manual, and they even state that the circulation pump will supply heat and help limit the need for the 6k watt heater, even though it takes less than 40 watts to run the pump. In fact, in summer mode, the circulation pump turns off for 8 hour cycles, just to help keep the water cooler....
Surprising, and it seems like a very good concept, but it does seem to work...now I wonder how hot the water is coming out of the pump when the heater is on? I have not tried that intentionally yet,,,,but I will in my soak tonight!
