In addition to my previous post, it looks like one may use an SSR control with The SYL-2352 to achieve the same result. I have used the Auber controllers with relay outputs in the past and every one of them has blown the internal relay within 6-8 months of use (no I did not exceed the amp ratings for the relay). Having upgraded to the SYL-2352 controller and using solid state relays has been a solution that proves to stand the test of time, no failures of the controller yet that is. The settings for programming the SYL-2352 up as a refrigeration control are as follows:

At = 0 (on/off control mode)
hy = 3 (+ or - 3 degree offset of setpoint, prevent short cycle)
t = between 60 - 90 (1 to 1.5 minute minimum on/off cycle, further prevent short cycling the compressor!)
cool = 11 (sets controller to cooling mode)

you may use the other settings in the manual to set your preference of decimal point position and F or C temperature readout.

I leave the high and low alarms at 100 & 0 F respectively, because in this case you will not be using the alarm outputs, I found that the 3A 120V rating of the alarm output is too low for my chest freezer compressor.

Great Thread but I have one question in general. Maybe i missed this elsewhere but where is the temp probe? Does it just read ambient inside the freezer or is it inside the fermentation vessel?

Thanks in advance.
