The Arctic Spa Pack integrates completely with the Arctic Heat Pump. As soon as you turn the temperature down below the tubs current temperature, the LCD display will switch and show “Chilling.” The Spa Pack will then send a signal to the heat pump to open its four-way reversing valve and in minutes will be chilling the tub.
Automatic Mode – simply set it and forget it. If the weather turns too hot, your spa will always remain at the temperature you set it to. If you want to have a cold chill tub but don’t want your spa to freeze during the cold season, the Northern Lights Arctic Spa system will add heat when needed to keep your tub from freezing and should the weather suddenly get warm, the system will start to chill.
