Q: Why compressor can’t start immediately after setting?
A: Until will wait for 3 min. to balance the pressure of system before start compressor again; it’s a
self protection on unit .
D: Why sometimes the temperature shown on the display panel decrease while unit is running?
R: When the upper tank temperature is much higher than the bottom part, upper part of hot water
will be mixed by the bottom cold water wich is continually flow from inlet tap water so that will
decrease the upper part temperature.
D: Why sometimes the temperature shown the display panel decrease but unit still keep closed?
R: To avoid unit ON/OFF frequently, unit will activate heate source only when bottom tank
temperature is lower than setting temperature for at least 5°C.
D: Why sometimes the temperature shown the display panel decrease dramatically?
R: Because tank is pressure-bearable type, if there is massive hot demand, hot water will quikly
tapped out from upper part of tank as well as cold water will quikly tapped into bottom part of
tank. If the cold water surface emerge the upper temperature sensor, temperature shown on the
display will decreased dramatically.
D: Why sometimes the temperature shown the display panel decrease a lot but there is still a mount
of hot water that can be tapped?
R: Because the upper water sensor is located on the upper ¼ of tank; when tapping hot water out,
it means there is at least ¼ tank of hot water available.
D: Why sometimes unit shows “LA” on display?
R: The heat pump available running ambient range is -7°C ~ 43°C; if ambient temperature is out of
range, system will show above mentioned signal to let user notice it.
D: Why sometimes there is nothing shown on the display?
R: To mantain display screen lifespan within along term, when there is no button operation for 30
sec. it will extinguish the display except LED indicator.
D: Why sometimes the buttons are unavailable?
R: If there is no operation on panel for 1 min. unit will lock the panel and shows “ ” ; to unlock
the panel, please press “ENTER” button for 3 sec.
D: Why sometimes there is some water flowed from drainage pipe of PT valve?
R: Because the tank is pressure-bearable one; when water is heated inside the tank, water will
expand, so the pressure inside of tank will increase. If pressure goes up more than 1 MPa (10atm),
PT valve will activate to relief the pressure and hot water drop will be discharged correspondingly.
If water drop is continually discharged from PT valve drainage pipe, it is abnormal; please contact
qualified stuff to repair
