(1) “ ” key: Repeatedly operate this key and the system will enter power-on-wait.
(2) “ ” key: repeatedly operate this key to enter and exit the “Smart” mode in the
power-on state.
(3) “ ” key and “ ” key: in the power-on state, touch this key to adjust the set
temperature.One time increases or decreases 5 (ie 30-35-40-45...80-30), long
press is invalid. “ ” for Decrease, “ ” means increase.
(4) After the power is turned on, the actual temperature of the display (constantly
bright)/set water temperature (flashing), when setting the appointment time
(flashing display). A fault code is displayed when a fault occurs.
(5) “Smart ” light: In the “Smart ” working mode, it flashes during the statistical data
period, and is always on after the statistical data is completed.
(6) “Heating” light: the light is on in normal heating state, flashes at 1Hz in antifreeze
heating in shutdown state, and goes out in non-heating state.
2. Function description:
a. Immediate heating: in the power-on state, the water heater directly heats, when
the water heater reaches the set temperature, it stops heating and enters the
heat preservation state. After that, if the water temperature drops below the set
temperature by 8 degrees, it will be reheated, and so on. The heating light is on
when heating.
b. “Smart ”mode: In this working mode, the system analyzes, processes and
memorizes the user's water usage habits for a week, and then the system will
heat in advance according to the memorized water usage time.
c. Antifreeze: After the system is powered on (regardless of whether it is turned on
or not), as long as T≤5℃, the electric heating tube will automatically start to enter
the heating state, and when T=10℃, it will automatically exit the antifreeze
heating state.
d. Power-off memory: When the system is powered off, all parameters and working
modes are saved. After the power is restored, the parameters before power-off
are still entered into the real-time working mode.
e. Fault code display: When the system self-check fails, the two-digit digital tube
flashes to display the corresponding fault code. Among them: the dry burning
fault is E2, the sensor fault is E3, and the over-temperature fault is E4.
