It is very easy. The whole unit adopts automatic intelligent control system. The user only needs to turn on the power supply for the first time, and fully realize the automatic operation in the later use process. When the water temperature reaches the user's specified temperature, the system automatically starts up and runs when the water temperature is lower than the user's specified water temperature, so that hot water can be available 24 hours a day without waiting. 2.Whether the heat pump unit can operate normally in winter with low temperature? Yes. Air source heat pump unit has intelligent defrosting function to ensure stable operation of the unit in low temperature environment. It can automatically enter and exit defrosting according to multiple parameters such as outdoor environment temperature, evaporator fin temperature and unit operation time.
