Hi I am currently trying to program some multi sensors to the specific requirements defined in the specs for job i am working on. The area the sensors are located in are the public corridors of an apartment building. Different sections of corridor are split into seprate lighting groups with upto 4 sensors controling one lighting group. Its not just one long corridor, there are 90 degree corners and sections where the corridors stop at lift lobbys then start again on the other side of the lift lobby. The requirements are: During daytime the sensors are set to Day Move/ Night Move with Light Level target set to around 250 lux (lights ON under 250 lux, lights OFF above 250 lux) At night time (so after sunset) all corridor lights need to dim to 50%, when movement is detected by a multisensor the lighting needs to ramp upto 100% for the set time (10 min atm) then return to 50% when the timer expires. Then at sunrise the corridors need to return to normal Day Move/Night move functionality. I have a touchscreen on different network that i can send a 50% dim at sunset command to all the corridor lighting so thats not an issue. But I am struggling with how i can get the multi sensors to go to 50% as minimum on expiry of timer during this night time period. Additional Information: All lights are DALI controlled through a gateway I am not currently using full Light Level Maintenance on the multisensors. I know i could be since the lighting is Dali dimmable but I just want to get above requirements working before I consider turning it on (It has normally just caused me more headaches than its worth when i have used it in the past so I normally stick with straight ON or OFF based on the ambient light level) Thanks Lliam
