Frozen protection: Green LED fhashes
When water inside the pump reaches freezing temperatures, it makes pump operated

The pump automatically stops after 10seconds when driving with no water inside the
pump. Automatically return to operation after 10 minutes.(Continuous dry running 10
seconds/10 minutes repeat when dry running continues.
Or the pump automatically stops when the temperature sensor is over 65 degree and
automatically return to running when temperature is less than 65 degree (for the first
time, it takes about 10 minutes operating and 20 minutes stop. After that, operating 1
minute / stop 5 minutes repeat).
It is possible to occur the dry running protection at maximum flow point. Thus, if the dry
