Description
TIMER
The unit starts and stops as the timer setting.
Once setup, this function works circularly every day.
RAPID
The electrical heater is started to prepare hot water rapidly to meet
the urgent need for hot water.This function is available only when
the water tank equipped with the auxiliary electrical heater.
I-KNOW
The unit
simulates the user’s habitual operation by collecting and
analyzing water data in some period and then realizes the automatic
operation. And it will remain medium water temperature when the
user does not require large amount of hot water.
CYCLE
The water pipe is preheated duly to ensure that hot water is
provided any time. Provision of hot water does not require
exhausting of cold water in the water pipe, which is different from
conventional water heaters.
STERILIZE
Water is heated to 70°C or higher (when the temperature can be set
to be higher than 70°C), to sterilize the water tank.
SUNFLOWER
By detecting the ambient temperature around a day, the water
heater enables the unit to run when the ambient temperature is
relatively high, which enables higher efficiency of the unit. At a lower
ambient temperature, the water temperature is kept at medium level
to meet users’ basic requirements.
ABSENCE
This function can be adopted when the user is absent for a short
time. This prevents frequent start-up of the unit and saves heat and
electricity.
VACATION
During the vacation set by the user, the unit keeps the water
temperature at a relatively low level to save heat and electricity. The
STERILIZE function is started one day before the vacation is over
and hot water is prepared by advance.
ONCE
The unit stops automatically after heating a tank of water. This
saves energy to the most extent when a tank of hot water is
available to the user.
