Automatic Dusk To Dawn, Astronomical Timer

The astronomical feature automatically adjusts the timer for dusk to dawn times so your lights will turn on and off based on the astronomical clock. In the summertime when there is more daylight, the timer will turn the lights on later in the evenings and turn off earlier in the mornings. Conversely, the timer will turn the lights on earlier in the evenings and off later in the mornings during winter when daylight is shorter. Simply select your time and zone, and the TGT01-H will do the rest!

No longer fumble for your keys in the dark trying to open your door. Never worry about accidentally leaving the lights on all day or night, and make sure they only turn on at the times you set with this digital timer switch.

Daylight Savings Feature

The auto Daylight Savings Time feature will automatically adjust the clock for time changes throughout the year, so your timer will continue to operate according to schedule.

Random Mode

The timer also features a Random Mode, which varies the scheduled time by about a few minutes (up to 30 minutes before or after) for an occupied look to deter intruders and thieves.

Timer Override & Countdown Timer

In addition to the timer’s programmable settings, the TGT01-H also has a manual on/off and timer override option. Override the programmed schedule to keep lights on or off, or even set a countdown timer for your lights!

Other Features

A bright, backlit LCD screen helps make checking and setting programs easier on the eyes. The timer backs up current programs and saved settings, so you don’t have to reprogram in the event of a power outage.

Benefits & Applications

TOPGREENER astronomic digital timers have many potential uses in the home. This product is ideal for automating lights to turn on when it’s dark out and off during daylight, randomizing light activity to make your home appear occupied when you’re not around, programming air conditioners, humidifiers, fans, and other appliances (make sure appliances fall below the switch load specifications), and running motorized blinds to protect carpets and furniture from fading when it’s sunny out (make sure appliances fall below the switch load specifications).

A manual override button allows it to function as a standard on/off switch too, giving you the best of both worlds.

Pair with a standard or screwless wall plate.

  1. Tim Morrissey

    Thing install easy, had a neutral in the box, so it was a breeze. Programming it to dusk/dawn performance: it appears that you do the d/d set up and that takes care of it. Nope. You do that then you must enter a ‘Program #1’. It asks for a ‘on’ time, but if you hiy the d/d button THEN it comes up. So the initial setup of d/d just activates that feature and sends that info to the ‘Program’. Took a while to figure that out.

  2. Manny G.

    Easy to install, programming requires some research on how to properly use the dusk to dawn function so that’s why I am taking a star off. Other than that, works as advertised. I saw other reviews stating it does not have a standard size – I am not sure if they changed the design but mine fit perfectly on the existing wall plate (rocker switch style).

  3. Kentaro T

    This light switch timer works great and turn on/off on schedule correctly. Installation is easy. The set to programming is easily to understand. And color is exact matched with my house wall plate. I’m very satisfied with this timer.
