Detection area

The rectangular detection area of the presence detector covers a large area and can be divided into 6 independent zones.

The 6 zones can be positioned either in the ETS, or via the thePixa Plug app. In the app, each zone can then be adjusted individually.

If the zones are entered via the ETS, it is imperative to observe the orientation of the presence detector when installing it.

Installation height

| Detection area walking| Detection area seated
---|---|---
2.5 m| 54 m2 I 6.0 m x 9.0 m|

22 m2 I 4.0 m x 5.5 m

3.0 m

| 79 m2 I 7.5 m x 10.5 m| 35 m2 I 5.0 m x 7.0 m
3.5 m| 102 m2 I 8.5 m x 12.0 m|

51 m2 I 6.0 m x 8.5 m

4.0 m

| 128 m2 I 9.5 m x 13.5 m| 79 m2 I 7.5 m x 10.5 m
4.5 m| 171 m2 I 11.0 m x 15.5 m|

102 m2 I 8.5 m x 12.0 m

The designation TOP indicates the orientation of the detection area.

Detection with night mode activated: Night mode switches on automatically at low surrounding brightness. In this mode, the detection area may be limited at a installation height of ≥ 4 m, depending on the application.

Brightness measurement

The presence detector measures the brightness of the entire area in each zone. The measured brightness is the average value of this area measurement.

Direct incidence of light on the presence detector influences the brightness measurement.

Avoid placing floor lamps or suspended lighting in the detection area.

For each zone, the current brightness has to be taught in with the smartphone/tablet (see chapter 4. Parameters, page 7.)

Constant lighting control

The zones must be arranged in such a way that each individual zone only captures its own artificial light. Artificial light controlled by other zones, or manually switched working lights, will affect the brightness measurement of the detector.
Avoid direct artificial light.

Switching mode

If the brightness measurement is deactivated, the lighting is only switched depending on presence.

Functions

Light

The optical presence detector switches or controls 6 lighting groups depending on the presence of persons and the current brightness. The brightness switching value or set point is set via parameters or objects (with objects only brightness set point).

Switching

The lighting is switched on when there is presence and low brightness, and switched off when there is absence or sufficient brightness. A button can be used to manually switch or dim, which stops the control for the duration of the presence. In addition, a free switch object is available.

Constant lighting control

When constant lighting control is active, the brightness is held constant at the brightness setpoint value. The control is started fully automatically or manually via button. Manual switching off or dimming stop the control for as long as the presence continues.

Standby
The standby function serves as an additional delay after the motion time delay has elapsed. The lighting will be set to the standby dimming value (1 – 25%) at the end of the time delay. The standby time can be set between 1 s and 60 min or permanently. The lighting is switched off if the brightness level in the room exceeds the brightness switching value/ set point. If the brightness level in the room falls below the brightness switching value/set point, the lighting will be switched on at the standby dimming value. The standby function can be activated or blocked via an object.

Button control

The lighting can be manually switched or dimmed any time via a button. If the light is switched on manually, it will remain on during switching mode for at least 30 minutes, provided people are present. Afterwards, it will be switched off if the brightness is sufficient. If the room is abandoned (before), the light goes out after the set time delay. With constant lighting control, the lighting is switched on and the control is activated. If the artificial light is switched off manually, the lighting remains off as long as people are present. At the end of the time delay, the lighting will switch automatically again.

Fully or semi-automatic

The lighting control is either fully or semi-automatic. As a “fully automatic device”, the lighting is switched on and off. As a “semi-automatic device”, the lighting must always be switched on manually. The lighting is switched off automatically.

Aura effect

The light accompanies the user to the area where he is at the moment. The surrounding areas are dimmed to a set orientation light value.

HVAC

For each detection zone (max. 6 zones) the presence information can be transmitted, e.g. for heating, ventilation or air conditioning control. Each channel has a switch-on delay and a time delay. The integrated temperature sensor also measures the ambient temperature and can be used for control purposes.

Switch-on delay

The switch-on delay prevents instantaneous switching on.
The telegram is sent only on expiry of the switch-on delay, provided that people are present for this time.

Time delay

The time delay allows a delayed switching off of HVAC devices and systems after the room has been left.

Room occupancy

In each detection zone (max. 6 zones), persons can be detected, which allows for anticipatory control, depending on the number of persons. The predefined 3 thresholds can be used to control a fan, for example. Corresponding links can be used to add up the number of persons from different zones.

Threshold switch

The 3 integrated threshold switches allow step-by-step control, such as the control of a fan.

Visual statistics/evaluations

With thePixa Plug app, heat maps as well as occupancy statistics can be displayed graphically and time-controlled. The heat maps can be exported via a .csv file. The information on occupancy statistics can also be called up via telegrams.

Start-up

Settings

Basic settings are made via the ETS (see application description in the KNX manual).
**** The presence detector supports KNX Data Secure.

For final start-up, thePixa Plug app is available. The BLE module integrated in the presence detector allows many functions to be called up or used directly with a smartphone or tablet, such as creating a background image, editing zones, calibrating brightness measurements, displaying statistics, etc. In addition, each brightness measurement as well as the integrated temperature measurement can be taught in. The control commands can be used to change the behaviour during operation.

During start-up, the steps on page 5 “IMPORTANT …” must be carried out.

Programming mode

Programming mode can be activated either with the programming button on the back of the presence detector or by using thePixa Plug app (without dismantling the detector). An activated programming mode is indicated by the illuminated LED on the programming button.

Resetting the presence detector to the factory setting

The presence detector is delivered with a factory setting that can be restored at any time.

Overview

Menu navigation is via a slider located in the upper area of the screen:

Grid – occupancy – heat map – parameters – control commands – zones

Grid

The motion/presence detected by the presence detector is displayed in green (motion) and red (presence).

Various algorithms are stored in the presence detector for different types of changes. This can lead to a motion/ presence being displayed for a short time longer than it actually exists. This means that those objects are displayed that are also forwarded to the KNX unit.

Occupancy

Graphical display of occupancy rate and occupancy density of the past 7 days, for each zone individually:

Occupancy rate: zone occupancy per hour in %
Occupancy density: zone utilization per hour in %

Heat map (“thermal image”)

Graphical display of the recorded motions over a defined period of time. (export as a .csv file possible).
Up to 24 heat maps can be stored and called up.

Detail settings for the heat maps

thermal image
A maximum of 24 heat maps are stored. After that, the recording is automatically interrupted.

Parameters

Temperature

Display of the currently measured temperature.
The measured value can be corrected by entering a new actual temperature.

Before the temperature calibration can be carried out, the presence detector must be in operation for at least 30 minutes.

Brightness zone x

Display of the currently measured brightness.
The measured value can be corrected by entering a new light value.

Perform the calibration at the desired surrounding brightness.

You must proceed as follows …

Select parameter .

Troubleshooting

Fault

|

Cause

---|---

Light does not switch on or switches off during presence and darkness

|

Lux value is set too low; detector set on semi- automatic; light was switched off manually via push button or with remote control; person not within detection area; obstruction(s) interrupting detection; time delay set too short.

Light is switched on in case of presence despite sufficient brightness

|

Lux value set too high; light was recently set manually by button (wait 30 min in switching mode); performing a firmware update.

Light is constantly switched on despite no one is present

|

Interruption of the mains voltage (230 V). After restoration of voltage, the detector is back in normal operation.

Light does not switch off, or light switches on spontaneously when no one is present

|

Wait for time delay to elapse (different time delays can be configured); optical sources of interference in the detection area: reflections of light influences, larger screens in the detection area, moving objects such as curtains when the window is open.

Smartphone/tablet cannot be connected with the detector

|

BLE not activated in the smartphone/tablet; interruption of the mains voltage (230 V).
