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 | Unit | Value Range |
|---|---|---|---|
| Online Status Nano 2 Relay Tree | Digital | 0/1 | |
| 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 | 0/1 |

|---|---|---|---|
| Monitor Online Status | When selected, 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. For Extensions: Enter 'Auto' to automatically pair an extension with unknown serial number. This can only be used if there is only one Extension of the same type. Save into the Miniserver, in order to pair the Extension. Afterwards the program must be loaded from the Miniserver to transfer the actual serial number of the Extension into the program. |

| Application | Specifies the intended use of the actuators. Universal: Outputs can be used freely Shading: Auto-Configuration will create a Automatic Shading function block |

| Automatically set drive times | Automatically learn travel durations for complete travels (Application: Shading). For learning, perform three uninterrupted complete travels to an end position. Open-close-open or close-open-close. This is not possible for motors with less than 100mA current consumption. In this case, please deactivate the option and set the travel durations in the Shading Block via the parameters (Opd) and (Cld). This function uses the current detection threshold. Set the threshold higher if some current still flows after the motor has stopped running. |

| Inverted Direction | Invert direction. Required when Up/Down connection is made the wrong way round. | - | - |
| Threshold for current detection [mA] | Current flow is detected when the sum of the current at both outputs exceeds this threshold. This is used depending on the application of the device: - Universal: The Current Flow input can be used in the project. - Shading: Used to determine if the motor is running or not, so the travel durations can be set automatically. |
