I have a temp controller in the pics:

I do not have any instructions for it, but it is quite simple. the display is the current temp of the sensor, pressing "SET" momentarily to change the set temp with up/down, press it for about 7 seconds to enter the menu and press again to scroll through menu items.

Not having any instruction the menu I have worked out some of the functions but not all;

"Menu Item" "Value" "Increment" "min/max" "Function"
E1 -35 1 ?
E2 90.0 1 ?
E3 2.0 0.1 0.1/? Temperature differential
E4 03 1 00/10 Compressor delay
E5 0.0 0.1 -/+ Temp Calibration
C1 0 or 1 Celsius or Fahrenheit
C2 0 or 1 Cooling or Heating mode
P1 45.0 0.1 ?
P2 -40 1 ?
P3 60 1 ?
P4 1.0 0.1 0.1/10.0 ?


Any ideas on the other functions?
 
e1 is low temp limit
e2 high temp limit
e3-5 you have


Not sure about the P menu items
 
Check out this pdf. Your one could be the same menu options as it also has the alarm output.

Thanks QldKev, it certainly looks like the one I have. I tried the high temp alarm, delay time and hysteresis, and it checks out.

I did some more searching and am reasonably sure that it is a ED330A , which has the same menu items as the pdf. I had searched most of the day yesterday but couldn't find zip, I guess that's the way it goes.

I have been testing this without a load and seems to be quite good. The default temp hysteresis seems a bit odd and am glad I can change this value now.
