Could you tell us what are you settings? (press and hold Set button)
PS. Is it scaled in F (not C) ???
I will once i get home this evening. I was really looking to getting a definition of what each setting was....

it is in F

I'll also take a pic of my wiring diagram



ROFL after looking through about 50 pages. I found the manual on page 249, going to confirm connections and set accordingly.

With my posts per page settings there are only 34 pages in this thread for me, so I'm not sure which manual you're looking at. Most of this thread is in reference to the STC-1000, which has different wiring and different programming than the unit you have, so the manual you found may or may not be helpful. Just in case the manual you found isn't the correct one for your unit, here's a diagram and some programming instructions-



Press the SET key once to enter the control temperature setting, press ▲ or ▼ keys to adjust your set point temperature. Press SET button again to exit setting mode.

Press and hold SET button for three seconds to enter the system menu settings, press ▲ or▼ button to select the menu, press the SET button once to enter the appropriate parameter settings, press ▲ or ▼ button to modify the parameters.

After adjustment, you can exit by pressing the RST key, or by waiting for 5 seconds.

Menu codes:
HC Heating or Cooling mode control
d Temperature differential
LS Minimum set limits
HS Maximum set limits
CA Tempreature calibration
PT Compressor delay

The compressor delay comes factory set to 1 min, so if you weren't waiting 1 min for the relay to activate after turning the unit on, that very well could have been your problem. Once you get it up and running, I'd suggest putting the compressor delay at the max setting (10 min) to protect your compressor from short cycling.

Hope this helps.

+1 for 10 min compressor delay. Prolonged lifespan guaranteed.

Hi

Very true except for *right now*. I just finished cleaning all my beer lines. When I do that I unplug the keezer. Just got it back on power and now I have to wait an extra 10 minutes to start cooling down..... I'm THIRSTY ....

Patient my friend, be patient! By saying prolonged lifespan, I was also refering to your livers

Hi

But my liver's thirst too....

Also looks like the short cycle prevention is doing it's thing just fine. Held off for 10 minutes after power up. Then cooled down and cut out. Since the beast is warm inside, it went back up pretty fast. Short cycle cut in and it holding off re-starting the compressor.

Still thirsty ...

Bob

That looks like the new single stage I just substituted for my STC-1000. It was labeled as a CH54 on the box. Just didn't like that celcius.

I see an interesting difference between yours and the two I just purchased. The front bezels of mine have "Work" or "Cool" on the left and "Set" on the top along with a ones digit that is short like the decimal digit of the STC-1000. In fact upon inspection it appears to use the same LED module as the STC-1000. However, your front bezel indicates "Work" and "Set" both on the left and has a full size ones digit. I notice these kinds of things.

Here's an image of both pages of the instructions that came with mine. If you can't read it, I can send you a pdf if you message me with your email address.

Hi

That's the WilHi something controller. Not as fancy as a STC-1000 and the relay is only rated to 5 amps. The STC-1000's are running about $17 delivered and the WilHi's are about $3 less.

Bob

The two I have are not labeled as Willhi's but they likely have a common source.


The relay is the exact same part as in my STC-1000 and is rated at 15A.

Hi

Yes indeed that is the exact same relay as the STC-1000. It's also the same PC board from what I can see in the picture.
