Frequently Asked Questions - GW14786 Gewiss

How to install the GW14786 motion detector?

Turn off the power supply, attach the wall bracket, connect the wires according to the diagram in the manual (phase, neutral, load), then adjust the time delay and brightness settings.

Why does my detector not turn on?

Check that the power supply is present, that the brightness threshold is set correctly (night position) and that the detection range is not obstructed.

The detector stays on permanently, what to do?

Reduce the time delay or check that no heat source (animals, radiator) triggers the detector continuously. Adjust the sensitivity if possible.

What is the detection range of the GW14786?

The range is about 12 meters with a 180° angle, depending on environmental conditions.

Can I use this detector outdoors?

Yes, the IP44 rating protects it against water splashes, but avoid direct exposure to heavy rain.

How to adjust the sensitivity of the detector?

Use the sensitivity potentiometer (if present) or adjust the sensor orientation. Refer to the manual for precise adjustments.

The detector triggers false movements, why?

Possible causes: animals, tree leaves, reflections, temperature variation. Try moving the sensor or reducing the sensitivity.

What is the maximum acceptable power for the connected lighting?

Up to 2000 W for incandescent lamps and 400 VA for compact fluorescent or LED lamps.

How to clean the detector?

Use a soft dry cloth. Avoid cleaning products that could damage the housing or sensor.

The detector does not react during the day, is that normal?

Yes, if the brightness threshold is set to 'night' or a low value, the detector only activates in low light. Set the potentiometer to 'day' for 24-hour operation.

GENERAL DESCRIPTION

The movement detector with EIB twilight switch - flush-mounted allows you to send an activation command to actuator devices using the KNX/EIB bus, according to the movements and light intensity detected.

The passive Infra Red (IR) sensor has an adjustable lens with fixed opening.

The detector is powered by the bus line and is fitted with two local potentiometers on the front, to regulate the light sensitivity levels and the variation of the recovery time (+/-50% of the value set via ETS), and a green indicator LED that signals movement detection and the consequential messages sent to the bus.

Functions

The device is configured by the ETS software to achieve one of the functions listed below.

Commands:

- send commands (1 bit/1 byte) of start and/or end of movement events

Other functions:

• movement detection conditioned or unconditioned by light intensity
• regulation of light intensity threshold or via ETS parameter
• function enabling/disabling via bus
• activation of command sending to bus object
• up to 4 auxiliary switching blocks
• safety pause with parameter options
• pure twilight sensor function

Completing installation

Insert the device into a Chorus support, making sure the front potentiometers are at the top.

Complete the installation with other Chorus devices or hole covers and fix it to the relative container (flush-mounted box, wall-mounted box etc).

Apply the finish plate.

PROGRAMMING WITH ETS SOFTWARE

This device must be configured using the ETS software.

Detailed information on the configuration parameters and their values can be found in the Technical Manual.

After completing device configuration it is possible to manually adjust the sensor and recovery time intervention thresholds.
