SINOTIMERTM619 Timer Switch Digital LCD Power Timer Switch Weekly Programmable Thinner Model 16A 1NO+1NC (TM619-3 24V)

We use then for resetting HVAC equipment once a day. Very nice timers, Note: you will need a un-switched power to keep the time working, having the display work does not mean the time will work. it only controls the NO/C/NC part of the timer. you can use a different power voltage for you device, but you need 24Volts (AC/DC) to keep the timer alive.

Instructions easy, install simple

I ordered two of these to put a month parking garage and they work perfect., However, the instructions need to explain a little bit better on how to choose your days on what days you don't want. The timer to open or clothes the garage gate other than that. It works pretty good. Took me about a week to figure it out but we got it.

I recently purchased the SINOTIMER TM619 Timer Switch Digital LCD Power Timer, and I must say that I'm quite impressed. It's basically a timer switch with a digital display that has more on/off options than the old mechanical timer I had. Installation just requires 4 wires to be connected.One of its best features is that there are no mechanical pins to push in order to set the schedule. With my previous timer, it was a constant problem, but this one makes things so much simpler. Furthermore, I saved over $100 by choosing the SINOTIMER instead of a replacement Pentair TMRLX 24-Hours Mechanical Timer.All in all, I'd say it's a great option if you're looking for a timer switch that's reliable, easy to install, and won't break the bank.

Good news: A really cost-effective replacement for the old mechanical timers that tend to break. A wonderful design, with an internal rechargable battery to keep the settings. Love the interface and timer. Bad news: Instructions are crap (as most Chinese instructions) and second. I replaced a mechanical timer in a complex control unit. The wires on the old one had plastic insulation on the clip terminals--very very standard--and the new timer did not have enough space to plug them in. This resulted in some very very annoying trimming of plastic insulation, all the while trying not to ruin the connectors or wires. It could have been so easy to install and so great to use. But it wasn't. So, I'm torn between a "1" for annoying installation and "5" for the price and replacement of a broken mechanical timer. I compromised with a "3". If your connectors are done by you, not a replacement device, and you use non-insulated terminals, this would go up to 5, IMO.

Did the job

Great
