Operation Manual

 Operation status

The light alarm code from the screen of SET TEMP. will appear and remind the user that the ambience

temperature does not meet the operation conditions of the heat pump unit (beyond the range of -7 ~ 43°C). The

user can switch the Economy Mode to E-heating Mode to ensure enough volume of hot water according to

needs. The appliance will return to operation pre-status automatically, when the ambience temperature meets

the operation conditions of heat pump mode and the error light alarm will disappear at the same time so the

screen display will become normal.

In case of continuous 20 hours when the season ambient temperature does not meet the heat pump

operation requirements (beyond the range of -7 ~ 43°C), “LA” error code will be displayed at TEMP SET

window and the ALARM indicator will flash simultaneously signing that the temperature does not meet the

heat pump performance. This time, only E-heating Mode can be set under these circumstances. Please switch

to E-heating Mode manually to ensure that the quantity and temperature of hot water supplied should be

adequate. When this is the case, the error code disappears and indicator alarm stops flashing and everything sets

back to normal operation

Error shooting

If some error happens, the buzzer will buzz 3 times every other minute and the ALARM indicator will glitter

fast. Press CANCEL for several seconds to stop the buzzer but the light will keep glittering.
