I am struggling with the Helvar distributer in NZ who beleives that the DALI gateway will not work with their ballasts & control gear despite me prooving it to them on their test case. I have done dozens of DALI jobs without too much hassle. Has anyone out there completed a job controlling Helvar ballasts with a C-Bus gateway? Also be warned that the Helvar folk have prooved very difficult to work with as they are trying to push their own controls. I am not looking foward to getting any support out of them should their product fail.
