7.Appendix1. Use for overheating protector
Overheating protector is used to prevent safety accident caused by water temperature inside the
tank too high in case that the heat pump controller is out of control. When the temperature inside the
tank reaches the action value of the protector, the power supply will be cut off. It has to be reset
manually so that the unit returns to normal. The operation in detail is as following:
Press the red button to reset
Protection cover of the protector
Be careful of electric shock when you press red button.
