Dan,

Does this unit allow you to set the ramp both going up and coming down?
Does it work with a solid state relay? How easy are the directions to
follow (assuming I can't read Chinese!)?

PID is described in the message below.

It's a basic temperature controller. You set the temperature you
want, the internal relay closes turning on your heater, if the
thermocouple says it's too high the internal relay opens so it's
basically an accurate thermostat. Since it comes without instructions I
have no idea what the relay specs are so I drove another relay with it.

There are two vertical 5 pin barrier strips on the back. The left pin
out is: 1-ground, 2 and 3 - 110 VAC, 4 and 5 are relay out. The right
pin out is: 6 and 7 - alarm, 8 - NC, 9 and 10 are the thermocouple.

I haven't tried the alarm function so I haven't bothered to figure
out how to set it. The power requirement is 100 VAC 50 cycles but it
operated rather nicely on 60 cycle for the half hour I tested it.

I still haven't gotten around to building my li'l oven yet. One of
these days I'll get around to procrastinating.
