This is the Frost Stat, a frost protection thermostat controller which switches the pump on when water falls below the set temperature. Forcing the pump on will move the water around, increasing pressure in the pipes which will lower the freezing point.
DHG-2 is a device designed to protect the pool water against frost while forcing the filtration pump to run when there is a danger of freezing due to the outside temperature.
Forcing the pump will move the water around and increase the pressure in the pipes which lowers the freezing point. Water suction from the main drain will pump the warmer water from the bottom and warm the water on the surface.
This device can't protect the pipes against frost when outside temperatures are very low and freezing lasts steadily over days. Users of DHG-2 will not be dispensed from other protection measures like pipes insulation, wintering floats, even pipes draining.
To effectively check the temperature of the pool, the Frost Stat features a digital display of temperature and is equipped with a temperature probe. Low and high set points are adjustable.
