EASY TO INSTALL Removable microSD

software and export
data (not supplied).
Energy Manager for the home is a sophisticated but low-cost, mains
powered integrated energy, heat and water monitoring package that
saves money by helping you reduce your energy consumption.
It is easy to install in new homes or retrot into existing properties.
The heart of the system is the NetThings measurement unit,
which is normally installed close to the home consumer unit, with
a mains power supply. The Unit can be wired with up to 6 sensors
for in-coming mains electricity, gas and water supplies or to monitor
the electrical output from solar PV systems, or the heat /cooling
output from solar thermal systems or district heating schemes.
CT (current transducer) clips are used for the electricity supplies,
pulse connectors for the gas, water meters and heat meters,
which are all wired in directly to NetThings.
On-going energy consumption and costs are stored continually
within the NetThings unit and can also be downloaded to a
removable microSD card (not supplied). Built-in WiFi allows Energy
Manager to communicate real-time monetary values of your energy
use directly with a local display in the home without requiring an
existing broadband internet connection. During the summer of 2015
NetThings will be launching their cloud service, where data will be
viewable from anywhere in the world via an internet browser.
The NetThings monitor and 5” local display screen qualify
for 2 credits under the Code for Sustainable Homes.

8 STEPS TO A SUCCESSFUL INSTALLATION
1. Please choose a suitable location for the display and Energy Manager.*
2. Ensure that a 13A power supply is available at these chosen locations.
3. If your chosen location for the Energy Manager is not adjacent to the services you
require monitored then run cabling between these during your rst x installation.
4. Fix Energy Manager and display in their nal position and make connections.
5. Make connections to the service you require to be monitored.**
6. Pair the display to the Energy manager.
7. Use energy on systems that you have connected to and check that this registers on your display.
8. Leave information with the end user for them to gain maximum usage of this product.
*As this product communicates with WiFi frequencies the signal from the Energy Manager should easily reach the display
within modern houses but solid walls and obstructions can affect this. If you are in doubt about the effectiveness of the
signal strength please check before installation. ** Additional equipment may be needed to connect to other manufacturer’s
products. Please contact NetThings if in doubt.
IMPORTANT ALL WIRING SHOULD BE CARRIED
OUT BY A COMPETENT INSTALLER OR ELECTRICIAN.
QUALIFIED TO WORK WITH MAINS ELECTRICITY AND
BE IN ACCORDANCE WITH IEE & BUILDING REGULATIONS
AND IN SOME CASES, NOTIFIABLE TO BUILDING CONTROL.
DO NOT CARRY OUT THIS INSTALLATION IF UNDER
THE INFLUENCE OF ALCOHOL OR DRUGS.
CAN CONNECT UP TO 3 PULSE O/P UTILITY METERS.
PULSE INPUTS ARE AT LOW VOLTAGE.
If you have any questions about installing
this product please contact NetThings or

WATER METERS
Water meters need to be specied as pulse enabled. Polarity
of pulse is not critical as pulses are mechanically generated.
GAS METERS
Ensure gas meters are pulse enabled and tted with the
appropriate pulse block. As there are several different types
please ensure that the correct pulse block is ordered.
If unsure check our support website for further information.
www.netthings.co.uk/support
ELECTRIC METERS
If monitoring solar PV systems then t an import export
meter and connect Energy Manager via pulse cables. Polarity
of connection is important here as it is an electronically
generated pulse. Observe pulse polarity when connecting.
HEAT METERS
Heat meters require to be pulse enabled and with a low
pulse setting i.e. 1 pulse per watt hour of energy.
