Welcome to our forum.
Well, we've had our Optima for one month and we are very happy with our purchase. Here's my review
A while back I posted a Q about using ozone with an indoor spa, and caused quite the debate. In my case it has turned out to be a complete non-issue.
"Also Sundance's "summer logic mode" which turns off all circulation and ozonator if the water temp goes 2 degrees above the setting. Nowadays, a cheapo programmable thermostat one can buy at their local Home depot has more processing brains then this. Sundance needs to add an outdoor sensor compensates for this."I don't get what processing information you are looking for and what an outdoor sensor would do. It is a very easy concept.Pump adds waste heat to water. Water heats above desired temperature. Pump shuts off. I am not trying to be condescending. If you could elaborate on what you would like to see, that would be helpfull. Thanks.
