When the minimum ambient operating température is reached. it automatically opens so that a minimum quantity of water may flow toward the drain, enabtmg a small continuous inflow of water; this prevents water from freezing inside the pipe. When the ambient température mereases or in the event of contact with warmer water. the opposite action occurs. causmg the device to shut off and circuit normal operating conditions to be restored.
