TECHNICAL INFORMATION

Energy metering and monitoring are at the heart of energy management, understanding when

and where your energy is consumed is key to 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 monitor device, switching appliances

on and off, to see the difference that each one makes. With a few small changes in your

consumption behaviour the e2 can help you reduce your energy costs.

IMPORTANT SAFETY INFORMATION

IMPORTANT: 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.

IN THE BOX

Your e2 Pack contains the following elements:

1 x mini CT Sensors

1 x Transmitter

1 x e2 Wireless Energy Monitor

You will need to attach the sensor to the live

feed cable which connects the meter to the

monitor. Any power you use in your home will

pass through this cable. The clip on sensor acts

as a CT sensor, and relays the amount of current

being drawn in the home to the transmitter.

From there it is sent wirelessly to the energy

monitor, which shows how much power is being

consumed.

You can upload your energy data from your e2

monitor onto your PC/Mac using elink software.

It also includes:

1 x USB Cable

1 x elink Software CD

1 x elink Software Guide

Locate Your Electrical Panel

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 Main Feed Wires for Your Home

You should ﬁnd four cables exiting the meter (see both

Fig. 1 and Fig. 2). The feed cable (cable 4) is the live

cable exiting from the meter to the fuse box. Connect

the mini CT sensor to cable 4. Some installations will

have cable 1 and cable 2 covered or partially covered

to prevent any tampering with the supply (see Fig. 2). In

this case you will still attach the sensor to cable 4.

MOUNTING INDIVIDUAL OR MULTIPLE CIRCUITS MOUNTING INDIVIDUAL OR MULTIPLE CIRCUITS CONTINUED

Dual Tariff Meters

Dual Tariff meters (shown in Fig. 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 mini CT 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.

Auxilary Cable

HARDWARE INSTALLATION

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.

Remove a standard 1cm knock out from the meter box. Feed the mini CT sensor lead from

inside the box out through the raw knock out hole. Open and place the mini CT sensor around

the live feed cable 4 (Fig.5).

Mounting the Transmitter

Insert the jack on the end of the mini CT sensor wire into any of the three input sockets on the

transmitter. The mini CT sensor acts as a current sensor and relays the current being drawn

into the home to the transmitter. Mount the transmitter on the wall next to or above the meter

box. This will make it easier to replace the batteries (although the batteries will last for a long

time). If the panel is in a ﬁnished area, you may mount the transmitter inside the meter box.

This may reduce transmission distance. Replace the panel cover(s) when ﬁnished installing the

mini CT sensors.

INSTALLING THE MINI CT SENSOR

Fig. 4 Fig. 5

1. Pull the release clip to open the

mini CT sensor (Fig. 4)

2. Select the correct feed cable, and

then place the sensor around it

3. Push the clasp to close around

the feed cable securely (Fig. 5)

MONITOR SETUP

Step 1 - Ensure three AA batteries are inserted in the transmitter

FAQS

1716

If I remove the batteries will I lose the information on the display?

The display has an internal memory, so if you need to change or remove the batteries

the information stored on the display will not be lost.

How do I reset the display (clear the data and start again)?

Press time period and unit set 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 230ft/40m within the home. The 433.5MHz range is

well suited for home use. This can cover three ﬂoors, and also well suited to buildings

where electricity meters are outside the main building.

I have 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. The LED backlight will be activated

from 18:00Hrs to 6:00Hrs.
