The frost guard ensures continuous filtration when the temperature falls below a predetermined value.
The device will start (forced) filtration when the air temperature is below the setpoint (adjustable).
This makes the frost guard the ideal addition to any hot tub. The frost guard ensures that the filter pump runs regularly, thus circulating the water. This prevents it from freezing in winter, even at sub-zero temperatures.
This way you can use your hot tub all year round. Or simply go on a skiing holiday.
