  • Page 4: General Description

    GENERAL DESCRIPTION Introduction The KNX occupancy/presence detector works on a passive infrared system, which registers heat movements and converts them to signals that can be analysed by a processor. The most important factor in motion detection is the right choice of mounting location. Mounting location The occupancy detector should be mounted so that the main direction of motion is always tangential (side-to-side across the device).

  • Page 5: Light Analysis

    With lighting regulation, the term used is not brightness threshold, but set value. Here, the detector sends a dimming telegram to the bus. If the ambient light (daylight) level is under the set value, and the detector registers a movement (1), the light switches on (100%). Then, using the brightness level determined (2), the light is dimmed until the set value is reached.

  • Page 6: Detector Operating Modes

    Detector operating modes The detector can operate in the following modes: 1. Full automatic mode In this mode, the lighting switches on and off automatically, according to occupancy and brightness, for greater convenience. 2. Semi-automatic mode In this mode, the lighting only switches on by manual operation, for improved energy saving. Switching off takes place automatically or manually.

  • Page 8: Ir Remote Control (Optional)

    IR REMOTE CONTROL (optional) In addition, GEWISS KNX occupancy and motion detectors can be controlled via the KNX bus using infrared (IR) remote control. The optional IR-PD-KNX remote control, item no. 92123, is available as an accessory Special functions The “Reset” button resets the detector. Here, the detector behaves as it does on bus voltage return.

    GENERAL SETTING Activate/deactivate outputs If light output or one of the three HVAC/occupancy channels is activated, additional parameter settings appear, for setting up detail functions. Only when a channel is activated do its parameters and communication objects appear. Test mode Test mode is for checking the detection area.

  • Page 11: Led

    Since the integrated LED can be detected as a source of interference in some locations, there is an option to switch it off after programming with ETS. The LED can be switched off and on as follows: • using the “LED – Input – General” communication object (1-bit “0”...

  • Page 12: Light Output Setting

    LIGHT OUTPUT SETTING Basic settings During project configuration, it is advisable first to set parameters for mode (full automatic, semi-automatic, slave or occupancy-independent regulation) and output type (switching or regulation). Output type affects the output object. In switching mode, a 1-bit object (15: Switching channel –...

  • Page 13: Output Type

    Output type The “Output type” parameter defines whether the detector should work in switching or regulating mode. In regulating mode, the detector regulates the brightness to the set value given. The corresponding dimming actuators on the opposite side are used for this. In switching mode, the detector only switches on and off.
  • Page 15 Regulation mode...

  • Page 16: Follow-Up Time Parameter

    4.2.1 Follow-up time parameter The follow-up time determines how long the lighting remains on after the last detected movement. Each new movement restarts the follow-up time. Follow-up time is set under “Follow-up time in seconds”, “Follow-up time in minutes” and “Follow-up time in hours”, and is produced by adding these three times.
  • Page 17 Using the remote control (optional), predefined follow-up times can be set (1 min, 5 min, 10 min, 15 min, 30 min, 60 min). The detector must previously have been unlocked for this (grey button, open lock). As soon as a new value has been specified via remote control or via the “Overwrite follow- up time in minutes –...

  • Page 18: Daylight-Dependent Switch-Off

    4.3 Daylight-dependent switch-off In the example (switching mode), the light value is initially above the brightness threshold. There is no reaction in terms of light output when movement is detected (A). If the light value falls below the threshold, and the occupancy detector detects movement, the lighting is switched on (B).

  • Page 19: Manual Control Options

    4.4 Manual control options The main task for a detector is automation of lighting. This results in energy saving from the lighting (light is only switched on if it is really needed), as well as increased convenience (light switches on automatically or constant light regulation maintains even illumination in the workplace).
  • Page 20 telegram can be sent, to set the dimming actuator to the desired value. This is a fixed value. It cannot be changed or modified during operation. Also, the detector only offers the option to dim the actuator using a push button. This manual dimming must be transmitted to the detector using the “Manual Dimming –...

  • Page 21: Brightness Threshold 1 And 2 (Switching) Or Set Value 1 And 2 (Regulating)

    4.5 Brightness threshold 1 and 2 (switching) or set value 1 and 2 (regulating) The set value or brightness threshold is the lux value desired for the room. This can be freely selected in a range of 5-1200 lux. Recommended values (room brightness): Transit areas: approx.
  • Page 22 On a mode change, the currently active mode is sent back via a response object, and can be queried via the “Actual set value/fixed value – output” communication object: set value 1 = 1; set value 2 = 2; fixed value = 3.

  • Page 23: Change Trigger Function

    4.7 Change trigger function In full automatic mode, the occupancy detector is activated by detection of a movement. In contrast to full automatic, semi-automatic mode means that switch-on must occur manually. This takes place via a 1-bit “1” telegram on the “External influence – Input – Light output” object.

  • Page 24: Manual Switching-On In Case Of Sufficient Ambient Light / Forced Shutdown (Switch Off)

    4.9 Manual switching—on in case of sufficient ambient light / forced shutdown (switch off) In full automatic mode, the detector automatically switches on as soon as it detects movement and ambient light is too low. If switch-on is also permitted via an external switch at high ambient light levels (above the selected threshold), this must be enabled through a parameter (Manual switching-on in case of sufficient ambient light).

  • Page 25: Centralised-Switching

    4.10 Centralised-switching If the detector has switched on the light because of a movement, the light can be switched off early by a 1-bit “0” telegram on the central object. This central-OFF command can be performed with a delay. During the delay period, the detector checks whether there is still movement taking place in the room.

  • Page 26: Locking Function

    4.12 Locking function The locking function allows the occupancy detector to be locked, so that no telegrams are sent to the bus. The locking function is available for both switching and regulating modes for lighting, and for the three HVAC channels. You must select a locking value to choose which 1-bit object value (“1”...

  • Page 27: Bus Voltage Return

    4.13 Bus voltage return After bus voltage return, the detector requires a 60-second initialisation time, during which it records neither motion nor brightness. During initialisation, it is possible to switch a connected actuator on or off. If all connected loads are switched on at the same time after a bus voltage return, this overloads the supply.

  • Page 28: Additional Functions In Regulating Mode

    4.14 Additional functions in regulating mode 4.14.1 Regulation (dimming) of two light groups (offset) If there is a requirement to regulate 2 light groups differently, this can be achieved using an offset. The base channel is defined as the “Value 1 – Output” communication object. If for example an offset of -30% is set in the parameters, the second channel switches on when the base channel has exceeded 30%.

  • Page 29: Soft Start

    4.14.2 Soft start When motion is detected, the detector initially switches on the lighting to 100%, and then regulates it to the set value. With the soft start function activated, the detector regulates from 0% to the set value when motion is detected.

  • Page 30: Orientation Light

    4.14.3 Orientation light The orientation light function is for providing dimmed lighting after the selected follow-up time has expired. This can be set as a percentage. Provision of dimmed lighting can be time- limited or permanently-on while no motion is detected and ambient light levels remain below the selected value.
  • Page 31 Burn-in time can be selected between 1-100 hours. There is an option to terminate a running burn-in time early, as long as the “Interrupt burn-in function” is activated. Therefore, a conscious decision has to be taken as to whether termination of the burn-in function should be permitted.

  • Page 32: Regulation Cycle Time (Cycle Time For Controlling)

    4.14.5 Regulation cycle time (Cycle time for controlling) The “Cycle time for controlling” parameter controls the time delay between individual regulation telegrams. If telegrams are sent too closely together, this can cause the lighting to fluctuate. Therefore, the standard time for this parameter is 3 seconds. If lighting fluctuation occurs, the “Cycle time for controlling”...

  • Page 33: Hvac Operation

    HVAC OPERATION 5.1 Introduction The occupancy detector’s light output is optimised for control of lights (switching or dimming). In addition to this output, the detector has three HVAC channels (HVAC = heating, ventilation and air conditioning). These channels are optimised for energy-intensive applications, for example air conditioning.

  • Page 35: Delayed Switch-On

    5.2 Delayed switch-on Depending on the usage of an HVAC channel, it can be useful to switch on the devices connected to it, such as HVAC equipment, with a time delay. The “Activation time” parameter is used to define whether the channel is switched on directly when movement is detected, or after a delay.
  • Page 36 (or else by an animal staying in their garden for a long time). Note: The GEWISS motion and occupancy detectors are not a certified alarm. They are not suitable for use in alarm installations.

  • Page 37: Occupancy-Indipendent Regulating Mode

    OCCUPANCY-INDIPENDENT REGULATING MODE Occupancy-independent regulating mode, the detector analyses the brightness level and regulates lighting independently of movement. This is advantageous if a particular light level should be maintained regardless of whether people are present, for example in bank lobbies or passageways.

  • Page 39: Master-Slave Systems / Occupancy Detectors In Slave Mode

    MASTER-SLAVE SYSTEMS / OCCUPANCY DETECTORS IN SLAVE MODE If an area larger than a detector’s detection area is to be monitored, additional detectors can be set up in slave mode. Two master detectors in a lighting system can lead to problems. Since both masters analyse brightness levels and specify follow-up times, and can influence each other optically, this can lead to interference in both regulating mode and switching mode.
  • Page 40 GEWISS KNX occupancy detector also has three HVAC channels as well as its base master and slave functions (light output). When setting up the parameters, the following options are available: 1. Detector is operating purely as a master 2. Detector is operating as a master and has additional HVAC channels 3.

  • Page 41: Special Case: Master-Master System

    7.1 Special case: Master-Master system If an area larger than a detector’s detection area is to be monitored, additional detectors can be set up in slave mode. Two master detectors in a lighting system can lead to problems. Since both masters analyse brightness levels and specify follow-up times, and can influence each other optically, this can lead to interference in both regulating mode and switching mode.

  • Page 43: Light Sensor Setting

    LIGHT SENSOR SETTING 8.1 Reflection Factor An occupancy detector includes a light sensor to measure brightness. Since the detector is mounted on the room ceiling, it measures the light there too. This means that it measures light which is present in the room (as sunlight and artificial light) and which is reflected onto the ceiling.

  • Page 44: Sending The Light Value / Correction Value

    8.2 Sending the light value / correction value The light value measured can be sent to the KNX bus. After enabling this function, the corresponding objects are visible. This offers a choice between sending the light value at intervals or when it changes. For sending at intervals, a time delay can be defined for the change in light value and the amount of change.
