Enerlites HET01-C Programmable Timer Switch for Lights, Fans, Motors, 7-Day 18 ON/Off Programs, Neutral Wire Required - White

Needed this to replace a switch that controls outlets that feed the Christmas lights along the eaves. The timer fits in the same space as a Decora switch. It's white where my house switch color is light almond, but the switch is in the garage and not noticed, so no problem. There are four wires on the switch: black (power), white (neutral) green (ground) and red (the load/lights). I determined the hot side of the switch with a voltage sensor before throwing the breaker. That hot wire goes to the black wire on the timer. The other wire in the original switch is the load and goes to the timer's red wire. Ground goes to the ground. The white wire has to be connected to a neutral white wire. With houses wired using Romex, there are usually a bundle of white wires in the junction box. I undid the wirenut and added the timer's white wire, then replaced the wirenut. Programming the timer is slightly tricky. First thing is to set the internal clock and tell the timer what day it is. There is an internal battery backup so it retains time, day and program should there be a power failure. There's also a Reset button if you want to clear it out and start over. Now that time of day and day of week are set, you can program separate on and off times for up to 18 events. You can program for single days of the week or just Monday through Friday or just the weekends. All I wanted was one event: turn on at 5 PM and off at 11 PM every day. I read the directions carefully and for Event 1, set it for on at 5 PM. You then have to set which days it will happen. You press "PROG" over and over until you cycle through all the days of the week, then M-F, then Sa-Su, then, finally, all the days are displayed. Next I set the "Off" time for 11 PM. Great. Finished. I set the "Mode" to Auto and closed the little door. Right on time, the lights turn on at 5 PM. Success! Except in the morning, the lights are still on. Turns out you have to set the days of the week the "OFF" command will happen, just like you have to set the timer for the days it will turn "ON." Sneaky. Re-read the instructions and went back into Program until the OFF time of 11 PM was displayed. I punched the PROG button until all the days of the weeks were displayed. NOW it works. Turns on at 5, off at 11, every day. With programming flexibility comes many options and many ways to foul up. But it works fine now. Excellent price. There's also a master ON/OFF slider switch under the door so when it's not Christmas season and there's no need to energize the outlets, they will remain off. You can manually turn the lights on or off by simply pressing on the little door. It's designed to punch the "MAN" buttons beneath the door so you don't have to open the little door to turn the lights on or off manually.

Me encanta que se adaptó a la placa que tenía actualmente. La configuración es muy completa y sencilla de hacerse.

Great switch and very easy to install. No need to run a separate wire just need to know how to connect everything properly in the switch box! I used this on my DIY grow light since most timers don't fully shut off the LED and they stay dim when suppose to be off (both mechanical and digital type). This switch works perfectly thanks to the neutral line connection and was easy to use and program as long as you FOLLOW THE INSTRUCTIONS! Highly recommend for led bulbs. Also has internal battery backup so your timer settings stay during a power outage.

I used this switch when installing a whole-house fan, and it works wonderfully to control the the motor. I plan on installing more of them for the outside/porch lights. I like the features and design better than anything I could find in local stores. Programmable Features: It is very easy to program, and the instructions are straightforward. The display is easy to read. It also gives you plenty of time to make your selections before automatically returning to the main display (I think 10 seconds for each button). The plastic door on the front doubles as the manual on/off override switch, which is nice. Construction: The switch seems well-built. The housing, face plate, screen, and buttons are sturdy and look like they'll withstand decades of use. Installation: It took me 3 minutes to install the switch. The switch doesn't have screw lugs but has the wires extending from the case to where you wire nut them directly to the box wires. The wiring is typical (black, white, red, green) and the schematic is clear. I read some reviews and questions complaining about not knowing what the different colored wires mean or what to do if the box doesn't have a neutral. Those reviews terrify the heck out of me considering those users have no business doing any kind of residential electrical work if they don't know basic universal wire insulation colors, don't know how to read a schematic, don't know what "hot" and "load" mean, and don't know how to fish a neutral into the box. Call an electrician before you burn down your house and kill someone. Overall, it's an excellent switch for the price.

Used for our outside lighting. Battery backup
