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 12min), 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

“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 30:0000:00. 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.

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.

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.
