A friend of mine had a Sundance spa with fried electronics which he was about to throw away, so I got it for free. The air blower, heater and the circulation pump is still good. The two blower pumps, the panel and the control unit is not there anymore, because they were thrown away when my friend was going trough the system and throwing away what was fried.
My intention is to just use it as a outside hot tub with air blowers. But I need a control system! I have found systems like Gecko and United Spas, but I have no idea if one is better than the other. It needs to run 230v since I am in Europe.
What are my options? And could anyone recomend any of them?
