INTRODUCTION

Energy metering and monitoring are at the heart of energy management, understanding when and where
your energy is consumed is key to saving money.

Efergy Energy Meters show 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 monitor can
help you reduce your energy costs.

SAFETY INFORMATION

WARNING! Your electric panel contains energized parts. This device must be installed by a
qualified electrician, unless otherwise permitted by local regulations.

It is important that you take some simple precautions before using this product. Incorrect use or
poor safety practices can result in injury or fatality. Whenever possible, turn off the main breaker
outside your home feeding power to your electricity panel.

When installing the Efergy Energy Meter you should find that everything is straight-forward. However,
there are a number of important health and safety issues which you need to be aware of:

 The current sensors clip onto the supply cables inside the main electrical panel, which delivers
power to your home.

 Do not touch any metallic connections during the installation of the sensors. Do not carry out
this installation if under the influence of alcohol or drugs.

 Remember the device is not intrusive and does not require rewiring; no wires or cables need to
be cut, removed or modified to perform this installation. 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 electric wires in the service panel or where the sensor is to be
attached, stop immediately and report the findings to your supply company.

4

 Efergy energy monitoring systems are considered plug and play devices that meet all regulatory
requirements for installation in the United States and Canada.

 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 throughout 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.

 Even with the main breaker in the off position, the connection lugs where the main wires
terminate at the main breaker may still be live with potentially lethal voltage. Stay clear of these
connections during the installation of the sensors.

 The sensors are insulated so do not be concerned if they slide down the main wires to the
breaker after being secured around the insulated wires. A plastic tie wrap (with 5cm of the tie not
cut off) secured to the main wire under the desired location for each sensor may be used to keep
them from sliding down the wires.

 Millions of these systems have been installed world wide without incident but please follow safe
working practices as outlined during the installation.

HARDWARE INSTALLATION

Efergy Energy Meters are installed by clipping the sensors around the feed wires of your electric panel.
In Canada and the United States, the residential voltage is 120V for small appliances and lighting and
240V for major appliances and equipment, such as central air conditioner, electric water heater and oven.
The AC/AC adaptor also needs to be installed on your service panel, this accurately measures the voltage
of your residence and powers the transmitter. Take care to follow the instructions within this guide during
the installation and call a qualified electrician if you have any doubts during this process.

Note: For a 120/240V panel (typical residential electric panel) power is measured using two XL sensors.
Set the reference point voltage during Monitor Setup to 120V or 130V for most rural installations. For
professional installation please consult the Technical notes for electrician section (see page 26).

7

Monitor installation considerations

The meter can be wall-mounted at a convenient location or taken throughout your home to determine
how much different electrical loads consume. Efergy Energy Meters update every 10 seconds, so you
can apply any new load and watch for the change in the reading on your display.

Find the main feed wires

__________________________________________________________

Locate your electrical panel

Hardware installation follows the same steps in
this case as with an 120/240V panel.

You can normally find your main electrical panel
inside your home on the other side of the wall
from your electric utility meter. You may also
follow the conduit from your utility meter. In many
cases it is located in the garage, utility room,
laundry room or hallway inside your home. If you
live in an apartment, it may be in the kitchen, a
utility closet or hallway. Also in the case of an
apartment, your voltage may be 120/208V.

Find the main feed wires for your home

Remove the outside cover from your electrical
panel and locate the main feed wires. You should
find up to four feed wires entering your main
electrical panel: two black wires, one white wire
and one green wire (there may not always be a
green or bare ground wire). The two black wires
(or sometimes one black and one red) are the live
wires feeding the panel, these are the wires used
to measure the power being used in your home
or business.

Install the AC/AC adaptor

__________________________________________________________

Step 1 - remove a knock out

Either wear proper protective leather gloves or turn off the power to carry
out this installation. Carefully remove a standard ½” knock out in the sub
portion of your service panel. Remove the locknut from the AC/AC
adaptor and pass the wires through the knock out as shown.

Run the locknut over the black and white leads of the AC/AC adaptor as
shown.

Step 2 - Screw the locknut

Screw the locknut onto the threaded hub of the AC/AC adaptor securing
the adaptor in place through the wall of the service panel as shown.

Note: The AC/AC adaptor is only to be used for powering the Efergy True
Power Meter Transmitter.

Step 3 - Install the white wire

Remove sufficient insulation from the end of the white wire, exposing the
bare conductor. Secure the exposed bare wire under a screw on the
neutral buss bar of the service panel. Typically, this will be an open solid
buss bar within the panel that will have many wires with white installation
secured to a common buss.

10

Step 4 - Install the black wire

Remove sufficient insulation from the end of the black wire, exposing the
bare conductor. Turn off any 15A single pole breaker and secure the
exposed bare wire under the breaker attachment screw. If all breakers
are in use, do not place two wires under the screw on the breaker.
Pig-tail the wires together into an approved wiring connector and
connect a single wire to the breaker.

Install the sensors

__________________________________________________________

Install a bushing

Locate a circular knockout and install a rubber bushing
(not included) on the top, side or bottom of the service
panel box that is convenient for routing the sensor wires.

Attach the sensors

Place the sensors around the feed wires of your electric
panel. Pull the clasp to open the sensor, place it around
the feed cable and push the clasp to shut.
The bushing is then pushed on to the sensor wires
outside the panel and then snapped into the hole.
Replace the panel cover(s) when finished installing the
sensors.

11

Connect to the the transmitter

________________________________________________________

Insert 3 AA batteries into the
back of the transmitter.

Plug the sensor lead with the “L” into the left port on the
transmitter, the sensor lead “R” into the centre port on the
transmitter, and the power supply lead into the square right port
on the transmitter. Turn on the circuit breaker used for the
AC/AC adaptor.
Then mount the transmitter on the wall next to or above the
electric panel. This will make it easier to replace the batteries.
If the panel is in a finished area, you may mount the transmitter
inside the electrical panel. This may reduce transmission
distance.

Replace the panel cover(s) when finished installing the the

adaptor and sensors.

 Programming the tariffs

Your monitor is pre-programmed so this process may not apply for you.

Your monitor has been pre-programmed from the factory in
accordance with the standardized Ontario time of use tariffs, including
weekends as off-peak. The display will also automatically change from
the ‘Summer Tariff Structure’ to the ‘Winter Tariff Structure’ in
accordance with your Ontario utility.
In the future, should any changes be required due to new tariff rates
or structures, your display may be easily re-programmed using the
following steps:

Program Design: The program has been divided into summer and
winter tariffs. Both summer and winter seasons are divided into 5
tariffs. Tariffs 1 through to 4 in both groups represent the 4 tariff
settings for weekdays (Monday-Friday) and tariff 5 is for weekends
(Saturday-Sunday). Keep in mind that tariff 5 is preset for weekends,
therefore you only need to set the tariff
cost using the off peak rate.

Start Programming: To start your manual programming press and
hold the MODE/SET button for 2 seconds. The currency symbol will
appear, this has by default been set to ‘$’, press the MODE/SET button
to go to the tariff and cost settings.

How can I reduce my energy use?

Efergy Energy Monitors show you how much energy you’re using, how much it costs, the average and
historic usage data.

 Once you’ve installed your energy monitor, walk around your home and switch off everything you
can, then walk around holding your energy monitor or app, and switch things back on as you go. You’ll
see the monitor reading increase when you switch on a new appliance.

 An energy monitor can help you to understand how much energy you’re using, which appliances are
costing you most, and how much you could save by switching items off, using them less or replacing
them.
According to the Energy Saving Trust, using an energy monitor could reduce your energy use by 5% ­15% in just a year. So if your annual electricity bill is £600, you could save between £30 and £90.

 Find out which appliances or rooms are costing you most, and use the information to help you
change habits and make cost-cutting decisions.

23

FAQs

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

The monitor has an internal memory, so if you need to change or remove the batteries and the
information stored on it will not be lost.

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

Press and hold the MODE/SET and HISTORY buttons simultaneously for two seconds.

How far does the device transmit?

The transmitter works up to around 130-230ft (40-70m) within the home. The 433.5MHz range is well
suited for in-home use. This can cover three floors and is also ideal for buildings where electricity meters
are situated outside.

I have dashes (- - - -) showing on the monitor. What does this mean?

If the dashes remain on the monitor this would indicate that the transmitter and receiver are not
communicating. Move the monitor closer to the transmitter and press the LINK button.

The backlight appears to work sometimes and then not others. Is it broken?

No, the backlight is on a timer to save battery life. The monitor should work at darker periods during the
day when any buttons are pressed. The LED backlight will be activated from 18:00 to 6:00 hours.
