CONTROLLER FOR THE AIR SOURCE HEAT PUMP WATER HEATER
EN
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 tempera
-
ture, 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 tem
-
perature at a relatively low level to save heat and electricity. The STE
-
RILIZE 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.
