2.1.2. MaxLight
Max Light is the maximum light output of a luminaire that it should take upon sensing occupancy. Maxlight can be easily customized and saved for each individual Response sensor node. Once the max light has been set to a particular value, the light output of that luminaire doesn’t exceed that value during normal or auto operation.
At the same time, the light output can still be manually changed to beyond this set value (ONLY if the set value is less than 100%) by temporary dimming operation (see more details here)
A Response Sensor Node enabled luminaire will have 100% set max light as default setting and the luminaire will always deliver 100% of its MaxLight level in response to direct motion and occupancy detection by its own PIR during normal/auto operation. If you enabled the Daylight dimming or assigned a scene configuration, then the MaxLight output will be different considering the present ambient light conditions and scene configurations.
2.1.2.1 How to Choose
A correctly designed lighting system will necessarily over illuminate a space when the luminaires are first installed. This is to allow for the depreciation in light output from the luminaires over time. In some instances, a space might actually be required to be over illuminated simply because the choice of ceiling and luminaire results in a higher lux level (i.e. due to highly reflective surfaces, or the spacing of luminaires at a later stage in the installation). If an area is too brightly lit, it not only consumes too much electricity, It can also create stress for occupants dealing with too much glare.
You can choose to set the MaxLight value within a range of 0 to 100%. We would recommend not to set any values less than 20% as the factory default setting of low light is 10%.
USE CASE: A simple case example: Imagine an open office space distributed with organic response enabled luminaires. All luminaires are in factory default settings. As sensors detect the motion (occupancy) they will have automatically cause the lights to go to 100%.
Usual recommended values for your office work area is 320-400 lux (may vary subject to regional lighting standards). You are intersted to see how much savings you can achieve by reduing the light output values to reach recommended lux output with maximum comfort. With a few clicks you can dim all the luminaires to intended light output for your whole zone e.g. 60% which is able to provide comfortable illuminance in that space. You have now easily achieved 40% light savings for all luminaires in that space. This 40% light savings could mean significant energy savings for the installation. In addition to lights now not only turning on where necessary will only deliver illuminance as much as necessary. This customization can be done individually to each luminaire and different spaces to suit all your different application areas.
Note: It is usually recommended that corridor and breakout areas can have their MaxLight levels reduced to lower levels than open plan or closed office areas as they have much lower recommended lux requirements which help save more energy.
By choosing the optimum MaxLight levels appropriately for the area, you can optimize the energy consumption and significantly improve occupancy comfort. As MaxLight is an attribute of an individual Response Sensor Node, the light output from each Organic Response enabled luminaire can be adjusted to exactly match the task being undertaken in the space under it. The system can easily be set to provide exactly the right amount of light in exactly the right place, whilst still allowing the flexibility to raise (or lower) the MaxLight of a specific light fitting above an occupant who requests more (or less) light.
The process of adjusting MaxLight levels across an entire building space to save energy and improve occupancy comfort is called “Trimming” and is covered later in this chapter under Trimming Using MaxLight.
2.1.2.2 Simple Configuration Steps:
Response IR App
Light output page in Response IR App has the feature called 'Set Max' which enables you to set a pre-configured value. ‘Revert to Auto Mode’ option will allow you to exit from any temporary dimming and ‘go to min’ mode, and restore the previously set MaxLight. Details of ‘Go to Min’ can be seen in here
Response App
Light out page in the Response App has the feature called ‘Set Max’ button which, upon pressing, will save the present light output as MaxLight. ‘Revert to Auto Mode’ option will allow you to exit from any temporary dimming and ‘go to min’ mode, and restore the previously set MaxLight. Details of ‘Go to Min’ can be seen here

How To Set the MaxLight (Response IR App) | ||
|---|---|---|
Commands | Response from Node | Response from luminaire(s) |
1. By pointing the IR dongle towards the right Response sensor node, you can choose to adjust the light output levels either by using Dim + or - button or by clicking on the right percentage levels shown under the ‘dimming level’. | Dome of selected node flashes red once to acknowledge receipt of each dimming command. | The luminaire will adapt to the changes and output will changes accordingly. It will increase in light output if you press Dim + button or scrolling the sliding bar towards right. |
2. Still pointing your dongle at the target node, press the Set Max button. | Dome of selected node flashes red once to acknowledge receipt of SetMax command. | The luminaire will immediately adopt this light level as its new MaxLight setting, and in future come on to this level in response to direct motion or occupancy detection. |
3. If you want to Relay this MaxLight levels within the same zone, point the dongle towards a single luminaire and press Zone + or - button. Once you achieved the required light output level, press the Relay button right next to Set Max. OR Go to the Dimming level option, point the dongle towards a Response sensor node, choose the required percentage from the list and press Relay button to make changes in all luminaires. Then press the Relay command next to the Set Max button in order to save the new MaxLight. | The pointed Response sensor node will flash twice upon receiving the Relay command. All other nodes will flash once during this relay.
Dome of selected node flashes red once to acknowledge receipt of Relay command, and then continues to flash red for 60 seconds. Dome of other neighbouring nodes will remain solid for 60 seconds upon Relaying these changes. | The luminaire will immediately adopt this light level as its new MaxLight setting, and in future come on to this level in response to direct motion or occupancy detection. |
4. If you make any temporary dimming and wants to go back to the previously set MaxLight, press ‘revert to auto mode’ button | The Dome of the selected node will flash once to acknowledge the changes in responds to every command. | The luminaire light output will keep changing when you make temporary dimming (Dim +/- command) and will restore the MaxLight output upon pressing revert to auto mode. |

Commands | Response from Node | Response from luminaire(s) |
1. Choose “Configure Nodes“ from the home screen | None | None |
2. Upon selection e.g. “Configure Nodes” Response App sends a 'Scan for Node ID' message in the background as you enter in “Light Output” menu and can see the “node selection“ at the top. | Dome of selected node will turn solid red to acknowledge selection of the node. | None |
3. If it is not the node you wished to select click on “Dismiss Node” or shake or pull down refresh on your phone to select another node. | The node previously selected will settle its red dome to off and newly selected node will indicate it is selected by its red dome staying solid red. | No |
4. Once you selected the right Response sensor node, start changing the light output by pressing Dim + or Dim - button or by scrolling the sliding bar towards left or right. Then press set max button once you are comfortable with the light output.
| Dome of the selected node will flash twice to acknowledge the changes in response to the temporary dimming command. And the dome flashed twice upon pressing the Set Max button.
| The light will adapt to the changes. The light output will change in response to the + or - button or scrolling the sliding bar. The light will save the max light value when you press the Set Max button and this will be the maximum light output during normal/auto operation. |
5. Press the query button right next to the set max, if you want to check or confirm the MaxLight value for a single luminaire. | Dome of the selected node will flash once to acknowledge the command | None |
6. If you want to Relay MaxLight within the same zone, toggle ON the Relay button and start making temporary dimming using + or - button or scrolling the sliding bar. And then click on Set Max button to relay it. | Dome of the selected node will flash 60 seconds to acknowledge the changes in command. Whereas all other neighbouring nodes will have solid red dome during the relaying command. | All luminaires within the zone will adopt to the changes in light output in response to the temporary dimming. Luminaires will save the new MaxLight and this will be the maximum light output during normal or auto operation mode. |
7. If you make any temporary dimming, and wanted to go back to the previously set MaxLight setting, press ‘Revert to Auto Mode’ button. ' Note: Please remember to toggle ON Relay button, If you want to relay the ‘Revert to Auto Mode’ command. | Dome of the selected Response sensor node will flash twice to acknowledge the ‘revert to auto mode’ command.
In case Relay, dome of the selected node will flash red for 60 seconds, whereas other Response sensor nodes will stay solid red for 60 seconds. | The luminaire will immediately choose the previously set MaxLight output.
The whole luminaires within the zone will adopt to changes immediately and goes back to the previously set MaxLight output. |
