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.Air to water heat pump is heating faster? Air to water heat pump heating rate according to the water temperature and outdoor temperature Summer inlet water temperature and outdoor temperature are high,so heating faster. In winner inlet water and outdoor temperature are lower,so the heating is slow.
