The Nano 2 Relay Tree is a compact module with 2 relay outputs, controlled via the Loxone Tree Technology.
The two relay outputs can either be configured separately or are used together as shading actuators. They are volt-free and therefore suitable for different voltages. The outputs share a common contact.

Mounting↑
Install the device in a suitable installation box.
Connect the power supply (orange/white terminal) and Tree communication wires (green/white terminals). Shortly after power-up, the status LED will blink orange if the wiring is correct (connection to Tree Extension and Miniserver is established).
Commissioning↑
Then follow the pairing procedure

| Summary | Description |
|---|---|
| Current Flow | Input is active when current flows through the relay outputs |
Actuators↑
| Summary | Description |
|---|---|
| Up | Digital relay output 1 |

Diagnostic Inputs↑
| Summary | Description | Unit | Value Range |
|---|---|---|---|
| Online Status Nano 2 Relay Tree | Digital | - | |
| System temperature | ° | ∞ | |
| Temperature Shutdown | If the CPU temperature reaches a critical point, the outputs of the device are switched off. This can be due to short-circuits, overloaded switching loads or too high an ambient temperature. | Digital | - |
Properties↑
| Summary | Description | Default Value |
|---|---|---|
| Monitor Online Status | When selected, you will be notified via System Status or the Cloud Mailer if the device is no longer available or goes offline. | - |
| Serial Number | Specifies the serial number of the device. For Extensions: 'Auto' may only be used if only one Extension of this type is being used. |
- |
| Device type | Tree device type | - |
| Application | Specifies the intended use of the actuators. Universal: Outputs can be used freely Automatic Blinds: Auto-Configuration will create a Automatic Blinds function block |
- |
| Automatically set drive times | Automatically learn travel times for complete trips (shading factor when used). This is not possible for motors with low power (less than 23W). In this case, this option should be deactivated and the travel times entered manually at Tu and Td in the automatic blinds. |
- |
| Inverted Direction | Invert direction. Required when Up/Down connection is made the wrong way round. | - |
| Threshold for current detection [mA] | If a current greater than the set threshold is detected the Current Detected output is activated. The current of Relay 1 and 2 are added up. - Used as universal actuator: Current detection can be used as digital input in the project - Other use: Current detection is used internally |
