The following features on eProWallbox can be configured via Bluetooth.

DPM:
- DPM enabling
- DPM Pmax
DPM 2.0:
- Electrical Installation
- Configuration
- Transformer ratio KI
- DPM Type selection
Load Unbalance
- Load unbalance enabling
- Load unbalance current

During the installation always refer to the meter installation manual included in the package.

Place the Power Meter provided after the main utility meter and before the split power
For the three-phase or single-phase electrical connection, refer to the dedicated meter installation manual included in the Power Meter package.
Feed the Modbus communication cables through the wallbox box sheath (C). Suggested cable: STP class 5E, 0.5 mm2 section.
If included connect the Current Transformers as indicated in the meter installation manual, paying attention to drawn through the clamp the line according to the direction indicated on the sensor. The neutral cable must not be drawn through the clamp.
Use the following order for connecting the communication cables from the PowerMeter to the Wallbox. Starting from left on the wallbox RS485 output port CN12
EM330

EM111

The preliminary steps for the next operations are the following:

Download and Install the application nRF Connect on your smartphone. F2meS suggests using an Android operating system
Open nRF Connect and Set a filter (e.g. “ePro”) in order to see only eProWallboxes in the homepage
Select Scan on the top right corner to identify the eProwallbox to be connected via Bluetooth through its Bluetooth name
Once connected to the desired eProwallbox, select Unknown Services to begin with the configuration
The Unknown Services contains all the parameters that can be written and read through Bluetooth

When powering up the Power Meter for the first time, tap&hold for 1.5 second, the central display button, at the bottom, until the display shows the page where to insert the password, initially set to 0000. You can edit each value using left or right display button and confirm each time by tap&holding the central display button.
For the three-phase Power Meter only, the system mode: 3Pn
To configure the Power Meter, tap&hold the left display button and set:
- Modbus address: 1
- BaudRate: 38.4 kbps
- Parity bit: Even
Set the model of Power Meter installed on nRF Connect app:
Parameter: DPM_TYPE
This field allows to select the Power Meter model installed
UUID : f0f924f8-34ce-4f1d-9791-b1b19ff3ffe4
TYPE: Uint8, select UINT8 on the app
VALUE:
- 00 → FINDER 3ph (212)
- 01 → FINDER 1ph (210)
- 02 → GAVAZZI EM330DINAV53HS1X
- 03 → GAVAZZI EM111DINAV51XS1X
If installed, set the Transformer Ratio KI on nRF Connect app:
Parameter: TRANSFORMER_RATIO_KI
This value allows to set the Current Transformer ratio according to the installed sensors. The value on the app is expressed in Hexadecimal
UUID: 0c8d04fc-247c-4119-ab10-77ad3779310c
TYPE: Uint32, select UINT32 on the app
VALUE: Set the Transformer Ratio KI according to the values printed on the sensor.
- E.g. 100/5 → KI = 20 (Hex value → 14)
- 150/5 → KI = 30 (Hex value → 1E)

TYPE: Uint32, select UINT32 on the app
VALUE: min value 0, max value 70000
Identify the UUID of the DPM Pmax parameter
Click on the up arrow next to the Unknow characteristic
Select UINT32
In “New value” field insert the contractual power value, expressed in Watt, from 0 to 70000. Then click SEND
The new value will appear on the main page, expressed in bytes

Parameter: DPM_ENABLED
This feature enable the DPM functionality
UUID: 9b5732b1-b557-40f7-ab72-fb00a3696 132
TYPE: Boolean, select BYTE on the app
VALUE: 01 enabling, 00 disabling
At the end of the process, to make the changes effective, restart the wallbox
Identify the UUID of the DPM Enabling parameter
Click on the up arrow next to the Unknow characteristic
Select BYTE
. In “New value” field insert: 01 to ENABLE 00 to DISABLE Then click SEND
The new value will appear on the main page

Parameter: LOAD_UNBALANCE_ENABLED
This function enables the load unbalance settings
UUID: aa29e099-f9dc-40a4-8612-afbb78c612df
TYPE: boolean, select BYTE on the app
VALUE:
- 00 → FALSE, disabled
- 01 → TRUE, enabled
Load unbalance current
Parameter: LOAD_UNBALANCE_CURRENT
This value defines the max allowable phases current unbalance expressed in mA
UUID: f9217d22-b703-4a2a-a565-38662afc1a9c
TYPE: Uint32, select UINT32 on the app
VALUE:
- 0 → Min value
- 32000 → Max value, in mA
