Query: Poor Product

Actually I had the E120C (20 amps) and had a bit more luck than many of the others who posted comments. Ours was used to control a timed exhaust fan for indoor air quality. It lasted almost 3 years before failing to the "No op" status. Cumbersome to program. Intermatic success in mechanical timers certainly has not carried over to electronic controls. I will likely try to see if the ST01C is truly improved before going to the Leviton timer.
