IntermaticWH40 Timer 7.75 x 5 x 3 inches Gray

This timer works perfectly/

Installed the Little Grey Box a few days after receiving. Watched a video on Utube, Took my time andfollowed the instructions as presented on the video. Start to finish in 45 minutes. Unit appears to be working as intended. After a week i have observed the Off / On cycles and will consider adjusting theon time to be no more than an hour,, twice a day.. As demand will dictate the best start times YOU may well have to adjust or add some more Off / On cycles to suit your specific needs.As advertised, The initial cost should be recovered in 3-4 months.. I will await to see the hydro consumption numbers on my bills to see how accurate they are..

Simple, time proven electromechanical design. Reasonably priced. Well built, all metal construction. Easy to install. Easy to set time and trippers. Terminals will accept up to #8 stranded wire. I’m using two of these. One on a conventional tank type water heater and one on a tankless water heater to prevent them from running during peak hours that my electric utility charges more for electricity. . Very satisfied.

At the time of writing, I've had this device installed (correctly) for a week and so far so good.My biggest complaint is that the installation instructions could be clearer. According to the wiring diagram inside the door, the white neutral wires connects to pressure plate A, but they are in fact meant to connect to pressure plates 3 and 4, which are marked as "line 2" on the diagram. The instruction flyer has a slightly clearer image indicating how to wire the device and I have attached said image to this review, I've even colored in the green ground wires.Once I figured out where the wires are actually meant to go, I had no problem installing the timer, but be warned that you need a minimum of electrical tools and know-how to do it safely.

i bought this to replace a similar timer and it fit perfectly and was easy to install. checked the progress and it works perfectly.
