Not sure without seeing the diagram but the power wire is the only one you should be breaking through the control. The neutral (white) wire and the ground (green) wire can get wired directly to the fridge.
A relay is basically a switch that needs its coil energized to open or close its contacts. The coil can be rated to accept various voltages so if you are going to use the 12 volt dc power supply make sure that the coil of the relay is the same. Also the contacts on a relay are rated up to a...
Going with 2 Ranco type controllers would probably be the easiest and cheapest.
I've seen products like this Product but you still need to buy a second sensor and the problem is that it can't handle the amperage draw of the heating elements. The Ranco is rated for 15A @ 120V and 8A @ 208V.
Check out the FAQ where it says it will use about 1.5 gallons of oil and that the fill line is the max amount of liquid that can be used safely.
Doesn't give you much to work with.
See if there is a contact rating on the controller. Usually there is a max amperage and voltage listing somewhere. If the contacts are handling 575 volts right now 110 volts for the refrigerator shouldn't be an issue.
Is there any info. on the pump as to how much amperage it draws? It sounds like you are tripping an overload protector on the power supply. When it cools down and resets you can power it up again and it will work fine but if the pump is rated for anything over 1 amp (1000 milliamps) it will keep...
I used to work on these and Traulsen makes a high quality product. The way this unit operates is by discharging air down from the right side and returns it up on the top left. The temperature control is adjustable sensing return air coming back to the coil. I'm not sure what the $200 temperature...
It depends on the size of the batch and how cold of a water source your working with. With 50' of 1/2" refrigeration tubing I am able to bring a 5 gallon batch down to 75 degrees in about 15 minutes using a submersible pump in ice water circulating at 170 GPH.
Trace the wiring from the main plug and at some point you will notice there are 2 separate leads. One lead goes to the common side of the thermostat and the other is your neutral. Just take one lead from the fan and wire it together with the neutral. Wire the other lead of the fan to the...
