The Keg King Dual Controller (MKII) 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 back of the unit. For example, get a chest freezer or refrigerator, and put a small 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.
All features are accessed through programming; <a href="/downloads/RJS/Q91_Instructions.pdf" target="_blank">see the instruction pdf</a> below for more details. Includes a 6’ waterproof probe cord with stainless probe tip, and a 4’ power cord. The stainless probe 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.
