BN-LINK Short Period Repeat Cycle Intermittent Timer, Interval Timer - Day, Night, or 24 Hour Operation, Photocell Light Sensor Dusk to Dawn for Hydroponics Aquaponics Aeroponics

Quality timer and works great! The dials are smooth and easy to set. It is fairly intuitive to use. Unfortunately, I need a timer that doesn’t draw additional power. This one carries about 1.5-1.7 watts to run in addition to whatever power is pulled by the appliance it is timing. It isn’t much, but is enough that it doesn’t meet the needs of my backup battery. Highly recommend if your system can handle that slight additiinal wattage.

I use this to cycle power to a heat tape wrapped around plumbing lines i have which isnt regulated by its own thermostat, works like a charm.

Good product and works well

At first glance, it appears to be good quality. It’s a bit confusing setting up night versus day versus 24 hour cycles. Anyone of these three cycles needs to be set manually and the light sensor does not automatic to switch it over. So if you want to have a day and a night schedule, you either would need to have two of these devices or change the cycle twice a day. This is not working for me, but it might be OK for other applications.

This was very easy to use and install. Does exactly what it’s supposed to. Inexpensive fix to my problem.

Before I bought the item ( UPC 680474115624 735090554484) I called the support # to verify the mode would stay programmed through a power cycle. Person I talked with first told me yes it would hold the programing then asked which unit I was considering and advised me it would loose mode program on a power cycle? Well the info on Amazon implied once programmed it would remember the mode so I bought the item knowing Amazon would allow a return. Bottom line unit holds the program even after being unplugged for days. In defense of the support person I did contact them on a Friday just minutes before they were going to close shop so they might have been in a rush to get out of work?

I am using this to control an electronic water valve which provides fresh water to my livestock; it's on for 2 minutes every hour. It replaced a much more $$$$ unit I had that conked out. It's been in use for a few weeks now and so far so good.

I've had this running for several months prior to writing this review. It is very easy to setup and does exactly what it says it will do. The dials are analog and fairly course which is acceptable for most applications. However, if you want real precision ( like exactly 25 seconds on and exactly 100 seconds off ) it won't deliver. After a little fiddling, I ignored the scale on the dial and used my watch to time the cycles to make adjustments. What I described above is "accuracy". However, that's probably less important than repeatability. The good news is, once set the unit is highly repeatable ( it will repeat the set cycle with minimal deviation ). The other positive is if you lose power, the unit powers back on and restarts the cycling without any additional efforts. The only possible negative for some, are the dials don't lock down. This means if you bump the dials at some point you may inadvertently change the timing. This isn't a problem for me since it's plugged into a wall outlet, but it may be a problem for some if plugged into a power strip on the floor where a foot or pet can move it. Overall I'm very pleased and would buy another if needed.

es un gran producto!

Super easy to setup and use. I tried different timers - one mechanical timer where I could setup for 30 minutes on and thirty minutes off. That one was OK but I really needed 20 minutes off followed by 20 minutes on continuously. This timer is perfect for my application, not only doing the 20/20 cycle, but it will allow for adjustments like 25 minutes on and 15 off. Fantastic!

Très bon produit . C'est mon deuxième et ils fonctionnent très bien .

Buen producto , muy funcional si no lo requieres con gran precisión en los tiempos de ahí muy bien

Great for controlling a basement fan , fully customizable on and off times ,
