Mine tries to hit 66, that's too low for my liking. So just running it won't work for me. Ambient temp in my place should be fine.
For those that are using the temp controller, how do you calibrate the probe?
I run an ETC 11100 upstairs and an STC1000 downstairs. They don't require calibration of the temp probe just input the temp settings and you're done.
For both units you basically take an extension cord (a good one not a cheapie lamp cord), cut it in half (not exactly in half but in the proportions to suite your needs) and wire it into the temp controller. You run the probe into the wino (I put mine high up and used an adhesive cleat and a zip tie to secure it), set the temp controller to operate within the range I want and thats it.
A benefit to these temp controllers is memory. The settings get stored onto an EPROM chip so if power ever goes out or flickers enough to reset the wino its not a concern. Once power is restores the wino resets its internal temp to the lowest setting but the temp controller takes over and only sends power to the wino if it needs to cool down.
This was a great option for me because we do lose power at least once a year and on those really windy days our power has been known to flicker or go out for a few minutes at a time. If Im home to reset it all no issue but I travel for work and the wife wouldn't remember to reset the wino. It also gives my OCD brain some relief.
ETC vs STC... ETC is a larger more expensive unit. Ive purchased them on eBay for under $50. The STC is under $20 all day long on eBay. Both are good units but after using both and experiencing an ETC fail on me after a few weeks I have opted to use STCs on both units. (I still haven't replaced the upstairs ETC yet). So why do I like the STC now?...
- its much cheaper so if it fails its not going to hurt the pocket book. Its also cheap enough I can keep a spare.
- it uses Celsius vs Fahrenheit so I have a tighter tolerance for the temp settigns.
- its a smaller unit so its easier to mount and less obtrusive.
How do they work?
They act as a sort of "gate" for power activated by a set temp.
When the temp hits a set parameter it sends power to the wino. The wino cooler runs until it reaches a set temp point then the controller turns power off. The supplied temp probe mounted in the wino reads the temp and sends the signal to the control unit.
