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.

SAFETY
IT IS IMPORTANT THAT YOU OBSERVE SOME SIMPLE PRECAUTIONS BEFORE USING
THIS PRODUCT.
When installing the Efergy monitor you should find that everything is relatively straightforward. However, there are number of important health and safety issues which you need
to be aware of.
It is 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 the
meter, then stop immediately and report the findings to your supply company.
IN THE BOX
Your Efergy Pack includes:
Sensor
Transmitter
1x Sensor
1x Transmitter
1x Display Unit
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.
Display Unit
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, which shows
how much power is being consumed.
Do not force or bend the cables at any point during the installation.
If you are worried or have any concerns about the installation, please contact a qualified
electrician immediately.
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 (UK)
The Efergy monitor is installed by clipping the sensor around the feed cable of your
electricity meter.
LOCATE YOUR ELECTRICITY METER
Diagram 1
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).

Diagram 2
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
metering device.
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
brown coloured).
If you have a three phase supply, or economy
7 meter, then you may require additional
sensors. These can be simply plugged into
the additional sockets at the base of the
transmitter. Please contact your supplier for
additional sensors.

FREQUENTLY ASKED QUESTIONS
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 mode and history 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 three 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 Efergy customer service to help locate the problem.
