When it comes to convenience, almost nothing beats the controls on a Sundance spa (except, perhaps, those recliners with a pocket on the side for the TV remote). Sundance gives you the power to easily change functions on an 850 Series: water circulation, hydrotherapy, aromatherapy, filtration, purification, temperature and lights. Customize water and air pressure, select jets, and control the most commonly used operations with just the touch of a button. All controls are easy to use and understand. You may also program the filtration and temperature settings to conserve energy, without using much of your own, of course.

Set the temperature or customize filtration cycles with precise results.

The digital 850 Series Sentry™ Command Control Panel displays a clear and legible readout, so it's easy to see the current water temperature. You can also flip the display around to read it right side up from inside or outside of the hot tub. All readings are accurate, as microprocessors check all functions 60 times per second, 24 hours a day, and redundant sensors ensure that the water temperature readout is accurate to within +/- 0.5 degree F.

Safety starts at the factory, where all electronics are tested and sealed to ensure they are waterproof. Circuit boards and touch pads are tested five times by five different inspectors. Primary touch pads have backlit, tactile buttons so you can operate the spa in the dark. Therapy jets are programmed for automatic shut-off after 20 minutes. A security code locks the control panel to prevent children or others from changing programmed settings.
