INSTALLATION OVERVIEW
8 STEPS TO A SUCCESSFUL INSTALLATION
1Choose suitable locations for the Energy Manager and Display, ensuring that the data ports on the
bottom of the Energy Manager are easily accessible for the end user. This product uses WiFi
technology to link the controller to the display. The signal from the Energy Manager should reach
the Display within modern houses but solid walls and obstructions can affect this. To ensure best
performance the distance between the Display and Energy Manager should not exceed 5
metres. If you are in doubt about the effectiveness of the signal strength please check before
installation.
2Ensure a mains power supply is available at these locations.
If your chosen location for the Energy Manager is not adjacent to the services you require to be
monitored then run cabling between these positions during your first fix installation.
3
Fix the Energy Manager and Display in their final positions and make power supply connections.
Make connections to the service you require to be monitored. Note: Additional equipment may
be required to connect to other manufacturer’s products. Please contact NetThings if in doubt.
Pair the Display to the Energy manager, complete the channel setup, and remove the yellow
commissioning warning banner.
Use energy on systems that you have connected to and check that this registers on your display.

SETTING UP M-BUS CHANNELS (only available on M-Bus supported Energy Managers)
The M-Bus functionality is only available on hardware that supports M-Bus communication. If the Energy
Manager supports M-Bus, a menu item for M-bus will be available in the Configuration page.
APPENDIX 1 –M-BUS CHANNEL SETUP
•Press M-Bus Configuration to start using the M-Bus
functionality.
•Once in the M-Bus Menu, turn the state from OFF to ON.
•In order to prevent any damage to equipment, when using
M-Bus mode, no pulse meters should be connected to
Channel 5-6. Confirm this is correct and press OK,
otherwise Cancel and connect Channels 5-6 to the M-Bus
communicating meters.
•The Energy Manger will now scan and search for M-Bus
enabled devices.

The scan results will show all meters that been discovered, however a maximum of 3 will have a channel
assigned.
When starting from an empty list, the order in which meters are found and allocated channels is dependant
on the sequence in which the devices communicate to the Energy Manager. On subsequent refreshes, if the
meters found are the same serial number and model, then the order is preserved.
The list of supported meters can be found on the ‘Installation Connections’ pages in this guide. Supported
meters will be correctly identified by type during the scan and should require no further setup. Unsupported
meters that at are discovered on the scan may need further setup to define the correct M-Bus records to report
on. The scan will try and find a record appropriate for the type of meter found, for example, on a Heatmeter, a
record containing a multiple of kWh will be sought. Further detail can be found below.
