Hi there, New to this forum and cbus. My boss is going to be putting me through some courses but has issued me a few challenges to get me stuck right in. Set up on my desk is an 8 channel dimmer, a PCI, a 5357L and a light. What I am trying to achieve, is when the occupancy is triggered, the light comes on at 70%. After 15 mins when no occupancy is detected the light drops to 30%. That's the easy bit. The next step is after a further 15 minutes to get the light to turn off. One of the other technicians has told me he has managed to get it working in the past. Says he had to do something with "Mem Toggle 2" under the Key Functions but couldn't for the life of him remember exactly how. -- So I have set up is block 2, with the lighting group, recall 1 @ 70 and recall 2 @ 30. expiry set as recall 2. This part works just fine. I thought the next logical step would be to set the next block, with a slightly longer timer to "Off Key" But alas this does not seem to work. -- I was wondering if I was one the right track, or if I couple please be point in the right direction. Thanks! Kiwi ) Edit: Next thought for experiment would be under key functions to set key 2 SP as toggle, to get the second timer going. I will have try this tomorrow.
