Wallbox 22kW 32A Tree

The LOXONE Wallbox is a charging station which enables dynamic three-phase charging from 4.1 kW to 22 kW for electric vehicles.

With the robust Tree Interface, the device is integrated into the LOXONE system and provides all the freedom for energy management.

A LOXONE Energy Meter 3-Phase Tree is built into the device ex works and is MID compliant, so the charged energy is recorded from the first charge — nothing to mount, nothing to wire.

Optionally, products like the NFC Code Touch, Touch Pure Flex, ... can be connected directly to set the charging mode or execute any other control.

Mounting↑

Attach the Wallbox vertically by screwing it onto a solid, even and closed surface.
Select screws and fastening material according to the surface.
Make sure that the mounting frame rests flush on the surface without any gaps.

For 1-phase operation, connect the phase conductor to L1. Phase switching is not supported.

After mounting, the supply voltage (mains voltage and 24V) is switched on, the Wallbox flashes orange after a short time if the connection to the Miniserver is successful and is ready for pairing.

Note: Do not install the Wallbox using magnets or place it near magnetic sources (closer than 0.5 meters). Magnetic fields may interfere with the internal residual current device, potentially affecting the charging functionality.

Commissioning↑

Then follow the pairing procedure on the Tree Interface.

After pairing the Wallbox, right-click on the device and select "Show installed meter" to view the serial number of the associated energy meter:

The pre-installed energy meter can now be paired via serial number or Tree device search.

Programming↑

The LOXONE Wallbox is programmed and set up using the Wallbox function block in LOXONE Config:

After pairing the meter, the Meter Type "Wallbox" and the Wiring direction "Inverted (Top = Out)" must be selected.
The meter can then be dragged onto the Wallbox function block to link it:

When a new vehicle is detected at the Wallbox, it can be assigned to a user in LOXONE Config via the "Learn Vehicle" button or directly in the LOXONE App via the Wallbox function block.

LED Status↑

Status LED	Description
	Device has just been paired or has restarted and is now online.
	Connection to the Miniserver is okay, but the device has not been paired.
	Device cannot connect to the Miniserver via the Tree interface.
	Device was selected in LOXONE Config and is identifying.
	Vehicle pairing mode is active.
	The connected vehicle is not known to the Wallbox.
	Charging started.
	Charging paused.
	Charging Error.

For detailed information about error codes, see Wallbox – Error Codes.

Charging Cable↑

The charging cable may only be replaced with the original LOXONE replacement part. Other cable types or lengths must not be used.

Limiting charging power↑

The LOXONE Wallbox is able to limit the charging power by transmitting the permitted maximum current to the vehicle.

Depending on the electrical connection, the Wallbox operates in either 3-phase or 1-phase mode. Switching between the two is not supported.

3-phase charging

1-phase charging

For 1-phase operation, connect the phase conductor to L1. Phase switching is not supported.

The actual charging power depends on the vehicle, supply voltage, and battery level, and may be above or significantly below the target charging power (Tp).

Summary	Description	Default Value
Monitor Online Status	If checked, you will be notified via System Status or the Mailer if the device is no longer available or goes offline.	-
Serial Number	Specifies the serial number of the device. Enter 'Auto' to automatically pair a Tree device with unknown serial number. This can only be used if there is only one Tree device of the same type on a standalone Miniserver (not in a Client-Gateway setup). Save in the Miniserver to pair the Tree device. Afterwards the program must be loaded from the Miniserver to transfer the actual serial number of the Tree device into the program.	-

Safety Instructions↑

Installation must be carried out by a qualified electrician in accordance with the applicable regulations.

Only mount on a solid, even and closed surface.

The selection of conductor cross-sections and associated overcurrent protection devices is dictated by national and international standards and installation guidelines. This requires choosing a conductor cross-section suitable for the loads rated current, as well as considering the insulation material of the cable, method of installation, and ambient temperature.
