Mounting↑

Install the device in a suitable installation box.

Connect the power supply (orange/white terminal) and Tree communication wires (green/white terminal).

Connect the orange MP-Bus lead to the MP-Bus nodes. The GND of the MP-Bus nodes must be connected to the GND of the Belimo Tree.

While 24VAC power supply is possible for many MP-Bus devices, the Belimo Tree can only be supplied with 24VDC.

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 on the Tree Interface.

For more information, please visit the Belimo Documentation.

Limitation of inputs/outputs↑

The number of usable inputs/outputs (IOs) is limited to 128 IOs in total per Belimo Tree/Air and to 20 IOs per Belimo device. Only IOs that are actually used on a programming page are relevant for this.

If these numbers are exceeded, an error message is displayed when inserting further IOs.

To solve this, IOs that are not absolutely required can be removed from the programming. Alternatively, use an additional Belimo Tree/Air.

Data Reading↑

Only the values that are actually sent to the Miniserver are displayed in the Belimo Monitor.

This means that only values that have changed are shown. The data is not displayed in the monitor with every polling cycle.
