different seasons:

z Operation in summer: Because the water temperature of tap water in summer is relatively higher (around

28℃). During the bathing period, you can directly select the prompt heating mode to heat the water, which

will save time while saving energy.

z Operation in spring, autumn and winter: During these three seasons, the temperature of tap water is relatively

lower, while the demand of hot water is relative higher during the bathing process, you can adjust the water

heater to “medium-temperature heat preservation” of “water storage type” or “preservation” mode to preheat

water. When the temperature of hot water is at a range of 35℃～40℃, you can use the “prompt/storage”

button to adjust the working mode of this unit to prompt heating mode to take your bath, thusly meeting your

demand of hot water while greatly shortening waiting time of your bath.

In addition, when there are many people to take bath, you also can adjust the water heater to “water storage

type” mode to preheat water, and then start the prompt heating mode to take a bath.

z Note: At the initial stage after the startup of prompt heating mode (the first 1～2min), the temperature of

outlet water will have minor variations. Please firstly adjust the water to the proper temperature and then take

bath in order to ensure the comfortableness of your bath.

 Conversion Method of Prompt Heating Mode

Under any water storage type of startup status, press the “prompt/storage” button to enter prompt heating mode,

“prompt heating type” will be illuminated, the time will count down with the limitation of 30 minutes, and the

display panel will indicate the decrease in the range of 30:00～00:00. If the system detects that the water flow is

greater than or equal to 2L/min, this unit will execute heating in the implied power of 3000W, and the “heating”

symbol will be illuminated. Within the working time period of prompt heating (30min), if the system hasn’t

detected water flow (e.g., the outlet valve is closed) or if the water flow is less than 2L/min, the working of the

heating tube shall be immediately stopped, and this unit will be under heat preservation status, the “heat

preservation” symbol will be illuminated, the count-down will continue. After the finish of the count down, it will

return to the previous working status (some water storage type prior to entrance of prompt heating mode. You can

use the “prompt/storage” button to re-enter into prompt heating mode.

3. Temperature Setting

Under status of startup (the display screen has no any digital flashing indication), press ∧ or ∨ to enter

temperature setting status to set the temperature (digital readout flashing quickly). The temperature value is

varied within the range of 35～75℃ with intervals of 5℃. Under standard mode, you can directly use ∧ or

∨ to adjust and set temperature; and under medium-temperature heat preservation mode, the implied

maximum heating temperature of this unit is 40℃, which can’t be adjusted.

Under water storage mode after the startup of this unit, refer to the method mentioned in the second clause,

continuously press the mode button, the unit will enter the working mode of night power (indicating the night

power symbol). If you want to use hot water in the morning, you can adjust the working mode of this unit to night

power, the unit will conduct heating/heat preservation at its default time period (startup at 00:00 and power off at

06:00), and the maximum heating temperature can be set and adjusted manually. In the mode, pressing the setting

button can be used to adjust theclock.

In addition, according to the provision of electricity consumption regulation at some areas, the electric rate at

nighttime is less than that of daytime. The selection of night power working mode will be more convenient and

economical.

Note: When you select the night power function, you should adjust the time of the water heater to local time. If the

time is inaccurate, it may result in the increased usage of electricity during peak times. (This clause only applies to

such areas practicing variable electricity rates)

For example: In water storage mode after the startup of this unit, press the mode button to select night power

working mode. When the clock on the computer panel indicates 00:00, this unit will automatically start heating,

and will enter into heat preservation status after the set temperature is reached, and the unit will conduct automatic

thermostatic control during the period from 00:00 to 06:00. (As shown in Fig. 13)

8. Intelligent Heating Function

When using the intelligent heating function, the system will conduct an analysis, processing and recording water

usage habits of the user during one week, and the system will conduct advance heating according to the recorded

water use time. In water storage type mode after the startup of this unit, continuously press the mode button to

enter intelligent working mode, the intelligent symbol will be illuminated, the system will enter into heating status

with the event of the first heating time after the current time, and the maximum heating temperature can be set

manually. During non-heating periods, the system will be in standby status, the clock and intelligent symbols will

be illuminated, and the unit will automatically start heating after the heating time is reached. If you want to leave

intelligent heating mode to enter other modes, you can activate the interface through any button on the control

panel, and use the mode button to toggle the modes.

Notes:

1) Under water storage type mode after the startup of this unit, intelligent heating function will automatically

memorize your water use habit. If you have taken bath during one week, the system will analyze and

memorize your habits of water usage, and will conduct advance heating before the same period of the next

week.

2) Only in the intelligent mode, can the intelligent functions be executed.

9. Reservation Time Setting

Reservation means that the system will automatically calculate the required time to heat to the setting temperature

according to default heating power of 2000W/1500W (40L and 50L units), and determine the starting time of

heating of this unit, and it will automatically heat to the set temperature before the set time of water use. Two

sections of reservation (reservation 1 + reservation 2) mean that the unit will conduct heating two times according

to setting requirements. The unit can manually set two levels of reservation times of water use, and the setting

time is based on the clock time on the computer panel. This unit will imply the reservation 1 of water use at 06:00,

and the reservation 2 of water use at 17:00.

Under water storage type mode after the startup of this unit, continuously press the mode button to enter the

working mode of reservation 1, the reservation symbol and figure will be illuminated simultaneously, press setting

button to enter the hour setting status of reservation 1, the hour digit of reservation 1 will flash, and press ∧ or ∨

to adjust to 10:00. Press setting button to confirm the setting and enter into the minute setting status of reservation

1. Press ∧ or ∨ to adjust the value to 10:30. At this moment you can press setting button to confirm the current

setting, or this unit will conduct automatic confirmation and exit the setting about six seconds after non-operation.

The time setting process of reservation 2 is similar to that of reservation 1, namely use mode button to adjust the

working mode of this unit to the working mode of reservation 2, and use setting button to conduct the time setting

of reservation 2.

Note: If this unit is under reservation status, and a large amount of hot water is demanded after the heating of

water has started, it will result failure reach to setting temperature after the water heater reaches the reservation

time. The unit will automatically delay the heating for half an hour and it will stop after that. If the actual water

temperature has reached setting temperature before the reservation time, and meanwhile it hasn’t reached

reservation time after the actual water temperature is reduced, this unit will conduct the calculation of heating time

again, and determine if it needs to conduct heating again. In like manner, if the voltage of electric network is too

low, the heating power of water heater will not reach 2000W/1500W, and it will result failure to reach the set

temperature value after the water heater has reached reservation time, this unit will automatically delay the

heating for half an hour and it will stop after that.

10. Standby

When bathing is finished, directly press the ON/OFF button to enter into standby status.

 Warming Hints:

A. Under a specific mode after the startup of this unit, press setting button to set ON/OFF time of each mode,

and adjust the time through ∧ or ∨. If it is in prompt heating mode, you can press setting button to adjust

hour and minute of clock; and under reservation mode, you can press the setting button to set the reservation

time. The setting button is disabled under medium-temperature/heat preservation and intelligent modes.

B. This unit has many safety protection devices, such as electricity leakage protection, over-temperature

protection, and short-circuit and open-circuit protection sensors, and it can realize full-circuit disconnection

and indicate fault codes. All fault protections are irrecoverable protection, and you must contact the after-sales

service department.

C. This electric water heater has a power-failure memory function, there is no need to reset heating power,

heating temperature, clock, and working mode after a power failure, and it will directly enter the same

working status of water storage type before the power failure.

D. In intelligent non-heating status, this unit is under standby status, and you can activate the interface through

any button on the control panel.
