The A12-1560 is a wonderful little control. Most uses are for small refrigeration, but I've even put them on problem walk-in's and have had great success. The key to taking the frustration out of the equation is understanding their use and application.

Their use:
Virtually any small refrigeration. Or any application where evaps freezing up is a common occurrence.

Their application:
Understanding the constant cut in is important. That constant cut in means you are guaranteed a defrost and clean evap before the compressor starts again. So how to mount it? You need to bury the capillary tube deep into the fins of the evap, that's how you make it work. It's pretty simple in practice, but maybe hard to explain. Remember, you need to get a bunch of that capillary tubing into the coils to sense that temp [you do not need a tube mounted from the manufacturer to put that capillary into].

Thanks for that. I pretty much get the purpose and do appreciate your response. I'm looking for a more technical approach to understanding exactly what they mean by the (3) off settings. Is it ok to take a 1560 and coil the end, and are there particular controls for certain specific applications? Like TXV vs. cap tube. There are a whole slu of cut in controls, how should one select the proper control for what he's working on.

Do not make it any more complicated than it really is.

Sure, coil the end if you want. Just be sure to bury it in the coil. The stat will then only sense the spot you put that coiled bulb.
