Electrodepot 7 Day 24 Hour Electronic Programmable Timer 120V with 50 Amp 3 Pole Contactor 30A, 40A 50A 3phase

Instructions could be more visual to understand the set up better. However, having said that, this unit has potential for people who are on time-of-use because it can run multiple appliances (3 large, such as a hot water heater and dual hot water heating elements) simultaneously during low-peak hours on this one unit. Other options are also possible. It works like a charm...on time, every single time. Great unit, and nothing else on the market like this one!
