Of the non-proprietary elevator control companys I dislike EC the second most behind smartrise. Being an adjuster/troubleshooter I find their literature the worst. Their tech support give the field mechanics the minimum amount of installation and troubleshooting guides. They want you to be dependent on their tech support engineers but that does little for the mechanic on a Friday night trouble call. Everybody has their opinion and this is mine. Pay the extra for motion control.
