READING YOUR DISPLAY
Upper screen
There are two speedometers to give
you an up-to-date graphical view of
how much electricity and gas your
home is using right now.
The upper electricity speedometer
shows up to 22kW of power, updating
every three seconds.
The lower gas speedometer shows up
to 50kW of power, updating every 30
minutes. (This speedometer is only
shown if you have a gas smart meter.)
The two gauges can be scaled to suit
the size of property you live in - see
‘Usage Level’ on page 18.
Lower screen
The lower screen is used to show
historical usage and also for making
changes to your Duet II.
The function of each of the three
buttons at the bottom of the display is
shown directly above it.
In the example above, the middle
button will enter the main menu.
Top (Home) button
A short press of the top (home) button
reverts the display to the Home View.

Duet II |User manual
WHAT DOES IT MEAN?
See what you’re using
Your Duet II display makes your
electricity and gas consumption
visible, taking the guesswork out of
understanding how much your home
uses - both right now and historically.
The display is neatly divided in two -
the upper screen shows the current
rate of usage of electricity and gas (if
installed) - the lower screen provides
an insight in to performance against a
set budget and shows when and how
much has been used in the past.
It’s about now ...
In the same way your car shows how
fast your car is travelling, the two
gauges in the upper screen show how
much your home is consuming now.
The top gauge - or speedometer - is
for the rate of electricity and the
bottom gauge is for gas.
To make it even easier to understand
the hourly rates of consumption, the
top and bottom sets of numbers can
show the rate of consumption in cost
(£/€) and energy or power (kW).
For example, if the display says £0.15
for the rate of electricity consumption,
then this means that if the rate stayed
the same it would cost 15p for the
next hour.
The electricity speedometer is
updated every few seconds and the
gas speedometer every 30 minutes.
Less is more
The lower the hourly rate of
consumption, the less it will cost and
the more you can save.
It is typical of a medium sized house to
use around 250Wh or 4p per hour of
electricity - so see how low you can get
the speedometer.
If, when you have your lights o, your
house is using more than this rate,
have a look around the home and see
if any appliances can be turned o.
The gas speedometer should drop to
zero when your boiler and cooker are
not in use.

What does it mean?
11
What is normal?
Don’t worry if every now and again the
speedometers are high - this can be
perfectly normal.
The image below shows where the
electricity speedometer will typically be
when using certain appliances.
Typical ‘base load’
Boiling a kettle
Evening time
How can I use less?
Look for appliances around the home
that are not always being used and
can be switched o.
Often it’s items such as a games
console, sound system or even a clock
radio in the spare room. Experiment
with switching appliances o and see
what aect that has on your daily
usage.
Other ways to save include having
less water in the kettle (only boil
what you intend to use), lowering the
temperature on the washing machine
or raising the temperature of the
freezer (-18OC is cold enough).

PREPAYMENT
Prepay view
If you are on a prepayment plan with
your utility, then your Duet II will
automatically show your remaining
credit on the Home View.
If you have both electricity and gas
prepayment plans, then the Home
View will alternate with the credit
remaining for each fuel.
You will also see the Pre-pay option
in the main menu. This allows you add
credit and view any outstanding debt.

Prepayment
13
Adding credit
To add credit to your electricity or gas
prepay smart meter, you will need to
have a unique code from your utility or
approved payment partner.
The code, also known as a ‘vend code’,
is 20 numbers long and can only be
used once. It contains details about
your account, smart meter and the
amount of credit you have purchased.
To enter the new vend code, do the
following:
• Press the menu button and select
the Pre-pay
• Select either Electricity or
Gas, depending on what you
have purchased
• Select Add Vend Code
• Using the left and right buttons,
enter each of the 20 digits,
pressing next/del to move to
the next digit
• A long press of next/del will go
back one digit
Once all 20 digits have been entered,
your display will send the code to the
smart meter for verication.
It can take up to thirty minutes for the
code to be applied and you will receive
a notication on your Duet II to let you
know the credit has been applied.
If the vend code was entered
incorrectly, please try again.
Press back to return to the
prepayment menu.
For other prepayment features, please
see ‘Electricity & gas prepay’ on page
14.

Taris
The Tariffs screen shows details of
the electricity and gas taris provided
by your utility.
Select next to view further details on
the individual Electricity and gas tari.
Understanding your tari
Tari information includes the current
rate per kWh (also known as unit
charge). If you have dierent taris
during the day, then the next tari is
also shown.
If there is a standing charge (either
each day or month), then this is
shown.
All prices are inclusive of VAT.
Tari now and next
To see what tari you are on now and
when the next tari change will be, the
upper screen has two sets of three
tari indicators.
One iicon means the least expensive
electricity tari and iii means the
most expensive. The icons will ash
to indicate a rate change is due within
the next 30 minutes.
As an example, if you have three
electricity icons showing (iii) and the
left-most icon is ashing - this means
that within the next 30 minutes your
electricity tari will move from the
most expensive to the least expensive
rate.
The same principles apply with the j
icons for gas taris.
Press back to return to the main
menu.

Backlight
The backlight of the upper and lower
screens can be congured to be active
at certain times of the day.
By default, the display will be o
between 22:00 and 06:00. During this
time, pressing any button will switch
the display on so that you can use
your Duet II as normal.
All settings are congured in 24 hour
format, where 00:00 is midnight, 12:00

There are three modes for the
backlight level:
• Off
• Timed (default)
• Always
When in Off, the display will
automatically switch o 60 seconds
after the Duet II was last used.
Timed is the default mode and means
that the display is on between the
Day ON and Night OFF times.

Alerts
There are 3 alert settings.
Volume
Your Duet II can make a sound when
there is a new alert.
The volume can be set between:
• Quiet (default)
• Loud
Audible
This setting turns the alert sound
either on or o.
You will still receive alerts when this
setting is set to Off.
Visual
This setting allows you to prevent
alerts generated by your Duet II from
appearing. Don’t worry, important
alerts from you Smart Meter will still
appear.
Usage Level
The dials in the upper display can be
scaled to suit your size of house and
expected usage.
For example, if you live in a ve-
bedroom house and have four people
living there all the time, then you
should select High as the user type
so that the dials can show the typical
higher rates of consumption.
Conversely, if you live in a small at,
then select Low so that your display
can make full use of the dials.
This setting only aects the electricity
and gas dials and does not alter
your readings or history and can be
changed at any time.
The options are:
• Low
• Medium (default)
• High
