Tip: Start by setting the Economic
mode and if you find that you are
not getting enough hot water,
increase it to
Normal , and so on.
!
Tip: Set the time about one hour
earlier than when you need the hot
water as it may take some time to
heat.
9.3 DHW
You use this to set the DHW comfort level you want and
extra DHW.
Temperature
You set the values for this option which apply to the heat
pump’s normal operation. There are three modes:
Economic – Small hot water requirement.
(Factory-set DHW tank temperature: 50 °C )
Normal – Normal hot water requirement.
(Factory-set DHW tank temperature: 55 °C )
Comfort - Large DHW requirement.
(Factory-set DHW tank temperature: 60 °C )
Extra hot water
Select this option if you want to activate the Extra DHW
function. When the function is activated (by setting the
number of hours) the heat pump immediately starts
to produce extra DHW. You also have the option to
schedule hot water production for certain times using
the Weekly program function (recommended).
The temperature is also determined by how the setting
has been performed in the Installer/Settings/Upper tank/
Extra DHW stop temp ºC menu.
The example above shows that
Extra DHW
is
On
for 3.5 hours.
9.3.1 Weekly program DHW
You can use this menu to schedule periods during
weekdays when you want extra hot water. This schedule
is repeated every week. The picture shows factory
settings that can be changed. If you want an additional
period some day, e.g. in the evening, you can program
recurring times.
Options for the weekly program are Off or Day by day.
Off
No scheduled hot water production.
Day by day
A weekly schedule which you program yourself. This
is used if you always know when you repeatedly need
extra hot water, for instance in the morning and evening.
On Monday morning at 6 am the system starts producing more
hot water until 9 am when the temperature returns to normal
again. There is a further increase between 6 pm and 9 pm.
