Essential Info

This Programmable Timer is an excellent choice for regulating your exterior lights, holiday lights, fountain pumps and other electronics into an automated on/off cycle. You have the option to set up to 20 programs from 1 to 7 days a week. Programs can be set as an on/off timed function, countdown function, and 3 modes of random functions to give your home that lived in appearance. What sets this apart from similar products is the built in photocell, which allows for the timer to turn on or off depending on the light recognition option you select. A manual on/off button is a convenient option if you wish to override your current timer status. The product was developed with outdoor applications in mind and built with a weather resistant casing and a slot on the back for mounting. The timer is ideal for heavy duty use with 120V loads using up to 15Amps, 1800W resistive, 600W tungsten, and motors up to 1.0 HP.

Hands-On Research:
The Heavy Duty Outdoor Programmable on/off Timer was very simple to use. The instructions were clear and concise, the buttons on the unit were large and responsive and the LCD display was easy to read. From start to finish it took approximately 30 minutes to work through the manual and test each function successfully. I liked that the product had a simple reset button, a built in slot on the back so that it could be wall mounted, and that the receptacle is located on the bottom of the unit. To increase the number of controlled receptacles, I added a PowerSquid and was able to control a total of 5 different items plugged in at once.


What's Included

  • Outdoor Programmable Timer
  • More Info

    Plug in the Heavy Duty Outdoor Programmable on/off Timer to a receptacle and press the reset button. Once that has been completed, take the lighting or electrical device you wish to control, plug it in to your module and you are ready to go. The unit is equipped with large buttons and an LCD screen that make programming a snap. Instructions are written in a basic and understandable language. Follow the directions for programming the day and time; time has the option of being displayed in 12 hour or 24 hour format.

    Programming Options
    With the basic time and day setup, the instructions take a step by step approach through the On Time and Off Time programming. Up to 20 separate timed programs may be created from 1 day to 7 days a week. The built in photocell gives the unit Daylight Control, allowing the timer to be turned on or off solely by the brightness of the surroundings. The Countdown timer will let the timer turn on or off for a period of time you specify, from 1 second up to 23 hours 59 minutes and 59 seconds. The Daylight Control and the Countdown Timer functions can also be controlled simultaneously. A Random function is also built in with which will allow your timer to turn on and off at random intervals; short term (1-2 hour), long term (2-4 hours), or program your own random timer. The timer also comes with a disable mode, that allows disable any one program or all programs

    Outdoor Design
    The casing is built of weather resistant material to withstand the elements of exterior use.

    The Heavy Duty Outdoor Programmable on/off Timer comes with a 1 year limited manufacturer's warranty. A similar Outdoor Timer is available without the photocell but with a drip-proof cover design that keeps water away from the keypad and a mounting wall bracket.

    Works Great! Easy to set up. Would recommend.
    STEVE -- odessa, FL   11/1/2010
    A very well made timer. It seems that it will hold up well to use. It has currently been in use now for about a month. Start and stop times can be programmed individually and set to the exact duration needed, not just in 15-30 minute intervals like many timers. Programming is very simple. Instructions are clear, but not really needed since programming is very easy.
    PAUL -- tucson, AZ   10/28/2010
    Works great Kind of hard to see the screen without using a light, but my cellphone provides enough illumination and I usually have it near by.
    PERRIN -- huntsville, AL   10/1/2010
    Not too difficult to use. Only annoyance was there are only 20 programmable, when 24 would be perfect for hourly on/off. Plants don't seem to mind skipping 2 feedings at night, though.
    ALLEN -- aptos, CA   9/10/2010
    I love this timer: it is so intelligently designed. 1) Most photocell timers assume you want to turn lights on at night -- I want to turn a fountain *off* at night. You can set this timer for light or dark. 2) It's very easy to program. The instructions are simple and well written, and you don't have to press meaningless combinations of buttons. 3) Our power goes out frequently, but I don't have to re-program the timer, since it has battery backup.
    DENIS -- quebec, QC   9/9/2010
    This timer provides numerous modes. A major feature is that all of its settings are kept in the case of a power outage. Programming requires considerable attention. While easy for the most basic modes it quickly becomes confusing and overwhelming as one gets into the more advanced modes, some I could never achieve. Instructions are terrible. They need to be rewritten, expanded, include state-diagrams of the programming sequences and provide actual examples. It is a pity that the hardware, which is well built and high quality, is not supported by adequate documentation. The reset trigger should also be changed: it is terribly frustrating to push it by mistake (it is identical to all the other switches) after going through a long programming sequence and losing everything. An easy and obvious fix would be to need to push it for several seconds in order to activate it. With adequate instructions, this would be a five stars.
    J W -- white bird, ID   9/6/2010
    Found the programmable timer to work excellent. The reason for the 2 star rating is the program instructions are extremely difficult to follow. Had to call tech support which quickly and successfully guided me through the process. The instructions as written are vague and leave out important info for those unfamiliar with the product and are gizmo challenged.
    SANDOR -- wilmington, NC   9/3/2010
    This unit was rated for a 1 hp motor but when I tried to control a 1/20 HP motor the electronics fried out instantly
    TOM -- mendon, MA   9/2/2010
    Great time. Seems rugged. Does everything it claims. Relatively easy to figure out and program.
    JEANNETTE -- duncan, BC   8/29/2010
    Only took about 5 minutes to program 20 separate programs. Works perfect for what I needed it for. Very happy.
    TODD -- austin, TX   8/23/2010
    Versatile. Works well. Looks and feels like it will last forever. MUST follow instructions to set it up.
    JERRY -- las vegas, NV   8/20/2010
    Excellent product saves me time and money, it works very well
    GEORGE -- mount vernon, WA   8/7/2010
    Pretty nifty. Has a little battery inside so you can unplug it. Works like a ...clock.
    JOSEPH -- sachse, TX   7/18/2010
    I needed a timer for a front yard light tree with six bulbs. The item I purchased needed only to be plugged into a power source and to plug the lights into the instrument. It took less than a minute to put it together. The programming was easily done. It has been working for several weeks now with no problems encountered.
    ROBERT G. -- walkersville, MD   7/15/2010
    Delivery was very fast and this timer words as advertised, unlike similar ones from the local big box retailer!
