Setting dimmer to start at 50% in device config?

I have a GE 45613 configured and working on my vera 3. It controls 4 led can lights 14W each. It stops powering the lights at above 50% dim. The lights go out and the dimmer becomes unresponsive for a couple of minutes. As long as I don’t ask more than 50% out of it all is fine. I am wondering if it’s possible to program the switch itself not to go higher than 50% so that if someone uses the switch manually it doesn’t shut down. I don’t see a parameter that fits my needs…

Thanks in advance
