This switch is the Honeywell-labeled replacement for the Aube TI071/U. (Aube, a Canadian corporation, was purchased by Honeywell.) I own the Aube-by-Honeywell-labelled switch. This is an easy install for a homeowner who is comfortable enough with electrical work to know why the wiring comes in different colors, and can identify which side of a circuit is "line" and which side is "load." Also, you must have a neutral (white) wire in the box where you are installing this, or the switch won't work. The switch benefits from Aube's years of experience in designing programmable thermostats that are easy to use. The initial setup involves determining your local latitude and longitude, which can be determined from Aube's web site or from using Google Maps. (You only need the degrees [such as 45° N or 75°W], not the minutes or seconds, nor any decimals following the degrees.) The date, time, and location are entered, and your preferences regarding when you want to see the backlight, as well as whether your location is affected by daylight savings time. Once this information is entered, you can program up to eight sets of ON and OFF times. The twist is in the "Solar Time Table" function. Entering latitude and longitude means that the switch calculates sunrise and sunset times for each day of the year, and those times are fairly accurate for your location. Therefore, you can set fixed on and off times for a program, or set ON and/or OFF to local sunset or sunrise. You can also adjust a time to be offset from sunset or sunrise, in ten-minute increments up to an hour either way. For my holiday lights, I want them to come on in the evening a half hour before sunset because our sunset comes earlier due to a ridge a mile west of our home. This switch allows that. It is also possible to have the switch turn off the lights a stated number of times at random intervals for a set period (got all that?). This is touted as good for vacation periods, though I have not tried it. In my experience, so-called "photo eyes" sometimes cause lights to come on during the day, or at times when they are not wanted. This switch will not let that happen. It is remarkable that Aube/Honeywell built such a degree of flexibility into a small package like this. I think this product is very well thought out, and I recommend it.
