The Keg King Dual Controller features dual plugs so you can control both a cooling unit and electric heater at the same time, via the separate heat and cool plugs in the bag of the unit.  For example, get a chest freezer or refrigerator, and put a Brewer’s Edge Space Heater inside the refrigerator. Plug both the Space Heater and Refrigerator in the Heat and Cool plugs on the back of the control, and set the temperature for 55° F.  The Keg King Controller will turn on the refrigerator when the temperature gets warmer than 55° and then turn on the Space heater if the temperature drops below 53° or so (depending on the delay you have programmed in).  Many things can be controlled:  wine cellars, fermentation areas, mash temperatures, green houses, pet enclosures,  your imagination is the limit.

 It can also be programmed to step temperature up or down over a period of time (up to 12 separate steps).  For optimum fermentation conditions using a chest freezer or refrigerator you can program the Keg King to start fermenting at one temperature, increase the temperature after a number of days and then crash chill. This is done without any intervention at all. Just program the control and forget.

You can also use this to increase the temperature of your electric mash tun so it will automatically step the temperature up and down as you please during a time period your specify.

 Distillation mode is included, which means it will only heat cycle the unit once. What this means is if you set the temperature to 175° F., it will heat until it reaches 175° and then turn off, sounding an alarm to let you know the heat has been turned off. This can be handy with electric distillation and other uses when constant monitoring is not needed.

 Other features include an adjustable differential, adjustable delay between the start of cooling and heating, or between the start of heating and cooling, cooling start delay, Centigrade and Fahrenheit modes, and adjustable high and low temperature alarms.

  Unlike the simpler Uni-Stat and Brewer’s Edge Mash Heat Control, all features are accessed through programming; see the instruction pdf below for more details.   Includes a 6’ waterproof probe cord with stainless probe tip, and a  4’ power cord.  The stainless probe fits in all the thermowells we sell, and is exactly 1/4" in outer diameter.  Works from -49°F up to 248°F, and features a 10 amp cooling relay, and 13 amp separate heating relay so it can handle the load of any 110 volt electric heater.

A common question we get is how to set the Dual Controller to Fahrenheit. To do this, follow the steps below:

 1. First hold the lower right set key down for about 6 seconds until it flashes E3.

 2. Then press the up arrow on the upper left 9 times to get to C1

 3. Then press the Set key and you will see the centigrade mode OO flashing

 4. Press the upper left up arrow once and you will see 01 flashing

 5. Leave it for 15 seconds and it will be set at Fahrenheit.

Great product
Great product at a decent price.  I'm very impressed with William's Brewing!  They always stand by their products and they quickly resolve any issues you may have.  It's no wonder why they've been in business so long.  Thank you William's Brewing!!!

Connected to Keezer (Fermentation Chamber)
Used with the Brewers Edge Space Heater, I had this hooked up to a 7 c.ft. chest freezer and it worked well to regulate a nice steady fermentation temp.  Also used it to crash out post fermentation to clear the beer up.  Very easy to use.  I did everything manual, but am planning to try setting a profile in the future for some other brews.

I also purchased a 16" Stainless Steel Thermowell to put the temp probe right into the middle of the brew..

easy temp control
I was looking at getting a PID and wiring it into the temp control on the Freezer and all that mess, but then I came across this and it’s perfect love it, works great. 
Cons; it’s all in Celsius but no bother I can do math. 
Yes I recommend it to everyone.

The brewing Gods have smiled on us!!!
If you want to be able to control fermentation temperature this is what you need.  To go from heating to cooling without having to reprogram or open up the unit and change jumpers it great!   Good God what took so long!  I have my fermentor in an old frig with a heating pad around it.  When it gets too cool the pad comes on.  When it gets too hot the frig comes one.  Neither comes on while the other is on.  It really works the way it should.  It's easy,  you don't have to be a programmer to make it work

Works great
This unit does exactly what I want it to do and does it well.  I also like that I can control heating from the same unit.

can this hook up to the refrigerator with messing with the temp on the freezer
No, it cannot. If you put the probe in the refrigerator and set it for say 60° F., it will turn off power at the plug to the refrigerator and work the compressor to get to 60° F. and then shut off. It will not be able to also monitor the freezer and control it, so the freezer will rise above freezing.
