Thank you very much for your response. I have two ballasts. I reset them to factory settings and measured the DC voltage on the control wires: First ballast: 0% 2.35v 10% 2.41 20% 2.44 30% 2.46 40% 2.51 50% 2.57 60% 2.65 70% 2.73 80% 2.86 90% 3.20 Second ballast for some reason does not change the control voltage -- it stays at 19.6v regardless of the current state values! I have no idea why I get the above numbers. Maybe the ballasts are bad (I had the contractor's electrician play with them before he gave up).

I am using 2477D (load capped) to control the ballast and/or ISY Admin Console Scene.

I have high-end Delta Lighting LED lights 0-10v dimmable installed. I have a problem controlling these lights with the Insteon Ballast Dimmer 2475DA2. I don't really understand what do I need to do to configure this correctly (I am pretty sure that the wiring is correct). What I get is that lights come on about 50% if I click On and 100% if I click Fast On. I cannot find a way to dim the lights. Could someone please help? Thank you very much! P.S. I attached the screen capture which shows the options dialog , but I am not sure what needs to be done.
