4. A To avoid unit ON OFF frequently unit will activate heat source only when bottom tank temperature is lower than setting temperature or max temperature for at least 5 C Q Why sometimes the temperature shown on the display will decreased dramatically A Because tank is pressure bearable type if there is massive hot demand hot water will quickly tapped out from upper part of tank as well as cold water will quickly tapped into bottom part of bank if the cold water surface emerge the upper temperature sensor temperature shown on the display will decreased dramatically Q Why sometimes the temperature shown on the display is decreased a lot but there is still a mount of hot water can be tapped A Because the upper water sensor is located on the upper 1 4 tank when display temperature starts falling down quickly it means there is at least 1 4 tank of hot water available Q Why sometimes unit shows LA on display A The heat pump available running ambient range is 7 43 C if ambient temperature is out of range system will show above mentioned signal to let user notice it Why something there is nothing shown on the display To maintain display screen lifespan within along term when there is no button operation for 30 sec it will extinguwish the display except the LED indicator gt Q Why sometimes the buttons are unavailable A If there is no operation on panel for 1 min unit will lock the panel shows
