I have a son of fermentation chiller and I want to upgrade so I bought a used Kenmore mini fridge to use as a fermentation chamber. The warmest setting is 50 degrees - too warm to ferment ales. I can buy a Loves controller but it will end up costing $70 ($20 to ship to HI) and I want to try to do something cheaper.
I saw a guy made a remote sensing DIY temp controller Wort-O-Matic: Remote Sensing DIY Controller for Less Than $25 and I thought I could try to control my mini fridge temp with this idea.
Could someone look at this page and let me know if I can do this with what I currently have? I'm interested in the second diagram towards the bottom of the page.
I have a 12VDC power supply that I am using for my old son of fermentation chiller -can I use that for the power supply in this configuration? In the diagram there are instructions that say 'Make sure the coil voltage is the same as the power supply. If you have a 24 volt DC power supply make sure to use a 24 volt DC coil relay.' What does that mean?
Also, next to the diagram on the web page it says 'Make sure the relay contacts are rated for 120 volts AC and are rated to handle the load amps.' What does that mean for me and my mini fridge? Can I buy a 12VDC relay that has relay contacts rated for 120 volts AC?
Any help is appreciated.
