1.4.3 DOmESTIC HOT WATER FUNCTION (DHW)
The hot water function will also be mentioned as
DHW
.
The production of hot water takes place in a direct and instantaneous way: you will never be without hot water as long
as electric power, water and gas are guaranteed.
The appliance is equipped with a sensor that keeps the temperature of the supplied water under control: this is source
of high comfort and extreme safety for every type of user.
It is always possible to activate the heating mode, during the hot water supply: this function will not be activated until
the production of domestic hot water is completed.
It is possible to keep both CH and DHW functions activated but
the boiler always gives priority to the use of DHW
mode with respect to CH
.
Hot water temperature setting
To activate and set the hot water temperature follow the procedure:
•
Press once the hot water mode button (
1
):
a ‘beep’ is heard and the icon
lights up; on the display the
previously selected temperature value is flashing;
by opening a tap, the boiler fires and the display shows the icon
as soon as the burner is on; the color of the hot water function
button’s led turns to orange.
•
Rotate the adjusting dial (
2
) to modify the desired temperature.
To deactivate the DHW function of the boiler follow the procedure:
•
Press once the hot water function button (
1
):
a ‘beep’ is heard and the icon
stops; the display does not show anymore the hot water temperature value.
The selectable temperatures may vary between 35°C and 60°C.
For safety reasons, all the taps must be closed before a higher value than 55°C is set. Hot water
must not be used during the operation.
In order to reduce gas consumption and to extend the water heater’s life, Rinnai suggests to set
the device’s temperature on the minimum which is more suitable for the intended use. Use hot
water on the pre-set temperature, so there is no need to mix it with cold water.
