  3. The sensor is plug-and-play and it will appear automatically in a "System tree" of the web interface.

Installation inside a rack or cabinet using a bracket

Mounting bracket

The mounting bracket is supplied with each "VT550 / Wind velocity meter". Use a wire cutter and pliers to cut and bend the bracket to Your needs.

Installation

The sensor measures the speed of the wind. If you install it too far away from the the air-conditioner, there will be no wind velocity or very little.

It is best to install the sensor as close as possible to the origin of the wind. The sensor should work in the stream and the correct installation distance should be obtained by trial and error.

The bracket steel thickness is 0.8 mm. Below You can find how users can mount the "VT550 /Wind velocity meter" with such a bracket.
