Yes it is intriguing how a device which looks like it is just wired in series with the active wire with no neutral connection actually powers itself up? There must be some sort of parasitic power using the active to the heater element as the neutral for the device to energise itselfIm with you Rob2.
Lets see a real circuit diagram showing what the components do, not just pictures of where the wires connect.
Im a sparky (been out of the trade for a while) and still cant figure out what this thing does.

No gimmicks, no ********, go build your complex devices if you think this controller don't work. I know it works.
I have already sold several units and am waiting for those buyers to get on here and tell you how good this this thing is, because some here don't seem to believe how such a simple thing works so good.
The only 2 problems potential buyers have is deciding how to safely mount it in some type of enclosure and what size element to use in the vessel!
This is not temperature control, it is voltage regulator. The lower the voltage, the less heat produced by the element. The element will not turn off when the water gets to a certain temperature, for that you need a thermostat.
If I have missed something, or got something wrong, let me know.
Or better still, go buy a mashmate and an element of 2400 watts. No relay needed and it will tell you the temp and keep the water at the set temp.....as most home brewers know.
And will only cost $88 for the controller and $35 for the element. You still need enclosure for either set up.
Yeah, I can't wait either.
One other problem....checking the temp. Either use a thermometer and keep re-setting this unit, or buy a mashmate and set and forget.....I have enough to do on brew day without trying to monitor the water temp.
If anyone is really interested on what this unit does go here [post="0"]http://www.answers.com/topic/solid-state-relay-1[/post]
And you will see that this is just a solid state relay and a variable resistor.

Look mate, if you don't have a need for this kit then fine but why are you trying to convince us that the guy is trying to rip us off or something? Not helpful.
You pretty much gotit there, it's the same as a dimmer control, like for the elements on an electric kitchen hotplate/stove. Reducing the heat the element outputs, maintains the temperature against overall heat lose, like when you are simmering a stew, you turn it on full at the start, then later, turn it down to simmer.
if its only controlling voltage, wont the element stay on, just a bit lower, thus still (slowly) increasing the temp?
That is exactly what I said.
It was a stove element controlled by a simmerstat that turns on and off
Remember this is the world where someone can put an RV on a highway, set the cruise control, walk out back to make a cup of coffee then sue the RV company when it crashed for a gazillion dollars because there were no adequate warnings or operating instructions supplied with the product..... I **** you not
Not to downlplay the risks of dealing with electicity and complex high load devices, but I am sure tired of that cruise control urban myth. http://www.snopes.com/autos/techno/cruise.asp
