New Durasport G2 Owner With Some Questions

Hello All!

My name is Jason and I am new to the forum. I live in Greenbackville, VA and I work with the NASA Wallops Flight Facility. I am also a first-time spa owner as of yesterday.

I have a few questions about my spa and I am hoping that someone else on the forum already has a G2 and can point out that I am just blind and not seeing the obvious.

1. I am right now connected to 110V, but I plan to make the switch to 240V as soon as I can get the electrician over to run 240V to that side of the house. However, in the meantime I want to use the spa. I plugged it in last night around 6PM. The water temp was right at 70F. I set the temp to the max of 104F. By 10PM that night, it had only gone up to 74F. By this morning, around 7AM, it was at 95F. Is this typical of a 110V system? I knew it would be slow at 110V, but it seems to be really taking a long time.

2. I noticed that after a couple of hours last night, the "cool" button lit up and it didn't appear to be heating anywhere beyond the 74F mark. I ended up having to push the heat button a couple of times and turning the jets on and then off to get it out of the "cool" mode. At least I think it was in a cooling mode. When I checked it this morning, it was at the 95F mark, but the "cool" was lit up again. Has any other G2 owners seen this? Is this a sign of a problem?

3. This morning, I was reading about the modes that are offered and it dawned on me that it might be in economy mode. The manual states to press either the cool or heat button, followed by the light button to confirm the mode. Pressing the cool or heat button just results in changing the temp setting and pressing the light button either does nothing at all or turns on the light. I think I am missing something in the button sequence, but I am not sure what. I would assume they would make this so any idiot could operate/program it (so it should be right up my alley :D ), but I can't seem to get it going to at least check what mode it's in.

Thanks for any help/advice in advance!

Jason

My 220 tub I had installed yesterday gained 10 degrees an hour with a 4000w heater. With a 1000w heater it seems it would take 4 times as long so id guess at 65 degree water it would take about 16 hours to heat. Just my guess.

OK, that makes sense. I understand that it was going to take much longer, I was just hoping that by the time I got up this morning it would be close to the 104F mark. I think the fact that "cool" turns on at some point automatically is contributing to why I'm not seeing it get up to temp. I left it running all day while I am here at work, so I'll check it when I get home. I am still very curious about the mode and how to get into that menu option in the controller. The panel is very simple with only four buttons and a small 4 -6 character LCD....

That brings up another question. Is there any way to upgrade the controller to some kind of aftermarket or do they tend to be so specific to the tub that it's hard to replace it?

I just got off the phone with a Durasport tech and he was able to really set me straight:

1. The "cool" LED lighting up is ACTUALLY an indication that the heater is ON. This is a bit confusing, since the LED is right under the "cool" button. However, the heat button does not have an LED under it, so they use the LED under the "cool" button to indicate this.

2. The temp sensor is actually only good to about the 70F mark. When I put in the fresh, cold water, I was assuming the temp reading was accurate at about the 70F mark. In reality, it was just reading the bottom number until the water's actual temp rose to 70F and above. Once it reached this 70F threshold, it started to display the actual water temp.

3. At 110V, the heater is running at 1000 watts. He said the temp rise is roughly 1 degree per hour at that rate. Once I switch to 220V, I'll see a quadruple to 4000 watts of heating. Also, when the spa is in 110V mode, you cannot change the mode, you can't even get into the menu. Once I have 220V connected and the DIP switches are re-configured for this, I'll have access to these advanced menus.

I hope this info will help any future G2 owners.
