HOW TO SET-UP YOUR EFERGY MONITOR
Energy metering and monitoring are at the heart of energy management: you need the
information to tell when and where you’re saving money.
The Efergy monitor is an Electricity Display Device or EDD that shows the amount of
energy that a household is consuming at the time the display is read. The display can
also give the user a reading showing usage in financial terms. You can walk around the
home with your display device, switching appliances on and off, and see the difference
that this makes.

IT IS IMPORTANT THAT YOU OBSERVE SOME SIMPLE PRECAUTIONS BEFORE USING THIS
When installing the Efergy monitor you should find that everything is relatively straight-forward.
However, there are number of important health and safety issues which you need to be aware of.
If you are in the UK or Ireland it is possible to carry out the installation yourself by installing the
device at your main electricity meter.
In other areas recommended that you contact a qualified electrician to carry out the installation.
The sensor clip fits onto the internal live feed cable inside the electricity meter or fuse box, which
delivers the live supply to your home. In some countries (i.e. Australia) the live cable can only be
accesed by a qualified electrician. Contact Efergy to find out if it’s mandatory for you to use a
qualified electrician in your country.
Please read and act upon the important information on the following pages. Remember the device
is not intrusive and does not require any rewiring.
If you notice anything unusual about the electricity supply or the fuse box, such as loose wires,
exposed cabling, burn marks, holes in the insulating materials or damage to themeter, then stop
immediately and report the findings to your supply company.
Do not force or bend the cables at any point during the installation.

Your Efergy Pack includes:
1x Display Unit
2x Velcro Pads
You will need to fit the sensor to the live
feed cable which connects the meter
to the fuse box (consumer unit). Any
power you use in your home will pass
through this cable.
The clip-on sensor acts as a current
sensor, and relays the amount of current
being drawn in the home to the
transmitter. From there it is sent
wirelessly to the monitor display unit,

The user does not need to remove the sensor through the working life of the unit. Battery changes
are performed on the transmitter and on the display. There are no batteries to change in the sensor.
FIND THE FEED CABLE IN YOUR ELECTRICITY METER
The Efergy monitor is installed by clipping the sensor around the feed cable of your
LOCATE YOUR ELECTRICITY METER
Locate your electricity meter and determine its type. You can
normally find this on an outside wall, in the garage, basement or
utility room. If you live in a flat, it can often be found outside your
front door, in the communal staircase, or in the basement. Ensure
there is enough of accessible cable coming from the bottom of
your electricity meter.
Modern office blocks and apartments may have safety panels to
protect wires entering the meter. It is recommended that professional
electricians be contacted where this is the case.
FIND THE FEED CABLE
You should find four cables exiting the meter. The feed cable (Cable
4) is the live cable exiting from the meter to the fuse box. Connect
the sensor to Cable 4 (Cable 4 will always be on the right hand
end of the meter, see Diagram 1).
Some installations will have Cable 1 and Cable 2 covered, or
partially covered to prevent any tampering with the supply (see
Diagram 2). Attach the sensor to Cable 4 (far right cable).
Dual Tariff meters (Diagram 3) will often
have an Auxiliary cable running between
Cable 3 and Cable 4. Auxiliary cables will
be smaller in diameter than the feed
cables, and will run into an adjoining
Newer installations will normally have two
cables exiting from the bottom of the meter.
One is the earth cable, the other the live
feed cable. The sensor should be clipped
around the live feed cable (this is normally
If you have a three phase supply, or economy

sensors. These can be simply plugged into
the additional sockets at the base of the

FIT THE SENSOR
Ensure three AA batteries are inserted in the transmitter
and the display unit.
The sensor needs to be fitted to the live feed cable. Sensors are suitable
for cables up to 11mm in diameter. You should not force the cable to fit.

drawn in to the home to the transmitter.
HOW TO SET UP YOUR EFERGY MONITOR
kgCO2 - CO2 EMISSIONS
The next function setting shows CO2 emissions per kWh
of grid electricity used. The UK average is 0.43kgCO2 /
kWh. This has been pre-set as the default value. Press the
green efergy button again to move onto the cost function.
Remove all packaging, insert two AAA batteries into the
transmitter and two AAA batteries into the Efergy meter.
You need to input the correct settings into the monitor. There
are seven settings in all; (Voltage, kgCO2, £/kWh, Alarm
value in kW Alarm on/off, Time & Date). All of them can be
accessed in that order.
Hold down the green efergy button for two seconds,
this will enable you to enter the function setting mode.
V - Voltage
Hold down the green efergy button for two seconds to
access the function setting mode. The first setting, which
is the voltage setting, will flash. This value is pre-set to
230V, the average electricity mains voltage in the UK. Use
the left and right arrows to change the voltage value,
down or up. Press the green efergy button once more
to store the voltage setting you have selected. This will also
move you on to the next function setting.

£ - COST / kWh
Select the currency and push the green efergy button
again to move onto the tariff function. This is the cost per
kWh charged by your electricity supplier. This has been
pre-set to 0.11p/kWh. On your electricity bill you will find
two tariffs. One is a higher rate for a set number of units,
whilst the remainder of units consumed is charged at a
lower flat rate. However, for simplicity, we have taken the
average of these. Press the green efergy button to move
on to the Alarm function.
The Alarm is set at 5kW as a default value. At any time, if
the Alarm is on, and you are using more than 5kW, the
Alarm will sound. This value can be decreased / increased
using the left and right arrows. Press the green efergy
button to store the value, and then use the left and
right arrows to choose whether to have the Alarm ON
or OFF. When the Alarm is switched ON, an icon of a bell

MEMORY MODE DISPLAY
Access to memory information
Press the memory button to access daily
data. Press again for weekly data and again
for monthly data. To exit the memory function
you need to press the memory button again,
the “M” sign will disappear.
If I remove the batteries will I lose the information on the display?
If you need to change or remove the batteries, the display has an internal memory, so
information stored on the display will not be lost.
How do I reset the display (clear the data and start again)?
Press Memory and Efergy buttons simultaneusly and hold for two seconds.
How far does the device transmit?
Transmitter’s works over 40meters within the home. The 433MHz range is well suited for
in home use. This can cover three floors, and also well suited to builders where meters
are outside the main building.
I have four dashes (- - - -) showing on the display. What does this mean?
Move the display closer to the transmitter and press the link button. If the dashes remain
on the display this would indicate the transmitter and receiver are not communicating.
Please contact Moeller customer service to help locate the problem.
Backlight appears to work sometimes, and not other times. Is my display broken?
No. The backlight is on a timer to save battery life. The display should work at darker
periods of the day.
The transmitter and receiver do not seem to communicate with each other, what
should I do?
