The product must be installed in compliance with standard CEI 64-8

for devices for domestic use and similar, in non-dusty environments and where special protection against water penetration is not necessary.

The GEWISS sales organisation is available for any clarifications and technical information.

Gewiss S.p.A. reserves the right to make any necessary modifications to the product described in this manual, at any time and without forewarning.

2 PACK CONTENTS

The supply pack of the KNX wind and rain sensor contains the following components:

1 KNX wind and rain sensor device
2 metal hose clamps
1 installation manual

3 GENERAL DESCRIPTION

3.1 Briefly

The combined wind and rain sensor measures the wind speed and detects atmospheric precipitation (rain or snow, but not fog or dew) and communicates the values to the KNX system.

It has 3 output communication elements of the ON/OFF type that can be associated with three settable thresholds for wind speed, and 1 output communication element of the ON/OFF type for signalling the presence of precipitation; it also has additional AND/OR logic ports.

The device shell houses the sensors and the electronics for connecting the KNX BUS.

1. Rain sensor connection cable assembled on the cover
2. Opening for the 230V AC power supply cable
3. Terminal for the 230V AC power supply; the terminals can be tightened for wires with a maximum section of 1.5 sq.mm.
4. Opening for the KNX BUS cable
5. KNX BUS terminal
6. KNX push-button for programming
7. KNX programming LED

3.2 Functions

• Rain detection: via the relative sensor, the device analyses the conductivity of the rainwater and immediately detects when the rain stops, thanks to the built-in heater.
• Wind measurement: wind intensity is measured electronically, in a quiet and reliable manner, even with hail, snow and sub-zero temperatures. The sensor also detects any air turbulence and thermal currents.
• Switchover outputs: 4 communication elements, 3 of which are associated with wind speed measurement and have settable thresholds (the threshold values can be set by means of parameters or communication elements).
• Logic operations: there are 8 AND ports and 8 OR ports, each supporting up to four inputs. The switchover values can be used directly as logic inputs. The output of each logic port can generate the sending of one communication item of 1 bit, or two items of 1 byte.

4 INSTALLATION

ATTENTION: the device must only be installed by qualified personnel, observing the current regulations and the guidelines for KNX/EIB installations.

4.1 Warnings for KNX/EIB installation

1. The length of the BUS line between the KNX sensor and the power supply must not exceed 350 metres.
2. The length of the BUS line between the KNX sensor and the furthest KNX/EIB device to be commanded must not exceed 700 metres.
3. To avoid unwanted signals and overvoltages, do not create ring circuits.
4. Keep a distance of at least 4mm between the individually insulated cables of the BUS line and those of the electricity line.

Bus ≥ 4 mm 230 V

1. Do not damage the electrical continuity conductor of the shielding.

2. Electrical continuity conductor
3. Shielding

ATTENTION: the unused BUS signal cables, and the electrical continuity conductor, must never touch live elements or the earth conductor!

4.2 Warnings for installation

Installation, inspection, start-up, and troubleshooting operations on the sensor must only be carried out by qualified personnel.

The device is designed for a specific, appropriate use, and any inappropriate modification or failure to observe the user instructions will invalidate both the warranty and any claims.

The sensor must only be activated after being correctly assembled and after completing all the installation and start-up operations, and only within the sphere of its intended use.

Electric connections

ATTENTION: disconnect the mains supply before connecting the device to it!

For the electric connection layouts, refer to the examples below.

1. Connect the red wire of the BUS cable to the red clamp (+) of the terminal, and the black wire to the black clamp (-).

Up to 4 BUS lines (wires of the same colour in the same clamp) can be connected to the BUS terminal.

1. Connection of the BUS device

2. Connection of the BUS cable

3. Insulate the shield, the electrical continuity conductor, and the remaining white and yellow wires of the BUS cable (when using a 4-conductor BUS cable), as these are not needed.

4.3 Positioning

For the assembly, choose a place where the sensor can detect the wind intensity and atmospheric precipitation without any hindrance. There must be a space of at least 60cm below the sensor, to allow the wind to be measured correctly and to avoid any build-up of snow.

The area above the sensor must be free of any objects that could produce drips even after the rain has ended.

Wall or pole 90°

The sensor must be assembled vertically, on a wall or pole.

Horizontal

The sensor must be assembled horizontally.

4.4 Fixing the support

The sensor is supplied with a surface-mounting support.

Fix the support vertically on a wall or pole.

Collar

Surface-mounting: the flat part on the wall, and the part with the protruding collar facing upwards.

Collar

Pole-mounting: the curved part on the pole, and the collar facing downwards.

4.6 Pre-arrangement of the sensor

1 Cover with rain sensor 2 Cover connections 3 PCB card 4 Lower part of the housing and remove

Unhook the cover and remove it by pulling upwards

The device cover has connections on the left and right, along the lower edge (see the figure).

Remove the cover carefully to avoid pulling the connection cable between the PCB card and the rain sensor assembled on the cover itself.

Push the power supply cable and the BUS connection through the rubber gasket on the sensor base, then connect the KNX BUS to the appropriate clamps.

4.7 Assembling the sensor

Close the housing by replacing the cover on the lower part.

The cover must be well inserted on both the right and the left (you should clearly hear a "click").

Fixing

Check the cover and lower part are well locked together.

This figure shows the closed sensor from below.

Push the housing down into the fixed support.

The protrusions on the support must clip into the housing guides.

4.8 Tips for installation

After powering the sensor, wait about 60 seconds before making a wind intensity reading and sending the switchover output value to the BUS.

5 PROGRAMMING

5.1 Application program

The application program can be downloaded from the website www.gewiss.com. Detailed information on the configuration parameters and their values is contained in the Technical Manual.

5.2 Programming the physical address

1. Power the device via the BUS.

2. Press the programming push-button to prepare the KNX sensor for the loading of the physical address from ETS.

To configure the device via ETS, both the main power supply and the KNX BUS power supply are needed.

6 MAINTENANCE

The sensor must be regularly checked (twice a year) for the presence of dirt, and cleaned if necessary. To remove the sensor, just pull it upwards (there will be some resistance from the fixing element). Do not open the sensor when it is raining, or in any case when water could get inside it: even just a few drops may damage the electronic system.

ATTENTION: for all maintenance and cleaning operations, disconnect the mains supply!
