Efergy E2 User manual

INTRODUCTION
CONTENTS
Energy metering and monitoring are at the heart of energy management: you need the
information to tell where and when you’re saving money.
The e2 wireless electricity monitor 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, to see the diffrence that each one 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 a number of important health and safety issues which
you need to be aware of.
Please read and act upon the important information on the following pages. Remember
the device is not intrusive and does not require rewiring.
In some countries (i.e Australia) the live cable can only be accessed by a qualified
electrician.
If you notice anything unusual about the electricity supply such as loose wires, exposed
cabling, burn marks, holes in the insulating materials or damage to the meter, stop
immediately and report the findings to your supply company.
Do not force or bend the cables at any point during 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.

Your e2 Pack contains the following
elements
1 x Sensor
1 x Transmitter
1 x Display Unit
You will need to attach the sensor to the live feed
cable which connects the meter to the 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,
which shows how much power is being
consumed.
It also includes
-1 x USB cable
-1 x Energy saving guide
-1 x elink software
-1 x Instruction manual for the monitor
-1 x Instructions manual for the software

FIND THE FEED CABLE
54
The e2 monitor is installed by clipping the sensor around the feed
cable of your electricity meter.
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 stair case, 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 generally 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 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.

UNDER NO CIRCUMSTANCES SHOULD
YOU TRY TO ATTACH THE SENSOR IF
THERE IS ANY DAMAGE TO THE ELECTRIC

BE CUT. DO NOT CUT ANY CABLES.

ABOUT CLIPPING THE SENSOR ONTO THE
CORRECT CABLE.

Link Button
Learn Button
If the LINK is COMPLETED
you will see the
transmission signal
If the LINK is NOT
COMPLETED you will see
dashes on the display
transmission signal
1. Ensure three AA batteries are inserted in the transmitter and
three AAA batteries inserted in the display unit.
2. Push the Link Button on the reverse of the display unit for 2 or
3 seconds. The transmission signal symbol will flash for one
minute.
3. While the transmission signal in the display flashes push the
Learn Button in the transmitter and wait until the transmission
signal symbol becomes solid.
Note: The default value for the transmission frequency is six
seconds. This means the transmitter is sending information
every six seconds. You can change the frequency from 6s (red
flashing light) to 12s (orange flashing light) and to 18s (green
light) pushing and holding the transmitter button.
1. Fit The Sensor
The sensor needs to be fitted to the live feed cable. Sensors are suitable for cables up to
12mm in diameter. You should not force the cable to fit. The sensor should fit loosely around
the cable and there should be no packing used.
2. Plug The Sensor Cable Into The Transmitter
Insert the jack on the end of the white wire into any of the three input sockets on the
transmitter. The clip-on sensor acts as a current sensor and relays the current being drawn into
the home to the transmitter.
If your cables are too big for the sensor you can order XL-sensors at www.efergy.com
1. Push the release cap
to open the sensor.
2. Select the correct feed
cable, then place the feed
cable into the top of the
sensor.
3. Close the sensor.
The sensor is secure
when a “click” is heard.

FAQS
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 Date Buttons simultaneously and hold for two seconds ‘clr’ will be
displayed on the screen.
How far does the device transmit?
Transmitters work up to around 40 meters within the home. The 433MHz range is well suited
for in home use. This can cover three floors, and also well suited to buildings 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.
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, when any buttons are pressed.
