$79.99

SKU# 40090

Control the Temperature. Control the Flavor. Just Plug and Play.

The Digital Temp Controller operates by overriding the internal thermostat in a refrigerator or freezer and gives the brewer greater control over the fermentation. Precise control of fermentation temperature is one of the most beneficial things you can do to improve your home brew beer.

It is also ideal for controlling the serving temperature of your kegerator or keezer.

Product Details

The digital controller has a digital display with adjustable differential. It can be used to heat or cool a fermentation environment. When hooked up to a refrigerator, it turns the compressor on when the ambient temperature rises above your programmed temperature; when hooked up to a heater, it activates when the temperature drops too low. A sensor probe monitors the temperature inside while the readout displays it in either Fahrenheit or Celsius. This is the ideal choice for lager brewers who include a diacetyl rest in their fermentations or for ales like altbier or Kolsch that require fermentation temperatures in the low end of the ale range.

External overriding thermostat with digital display with adjustable differential.

Features:

  • Plug 'n play - this controller is pre-wired, so you don't need a degree in electrical engineering to get it up and running.
  • Easy-to-read display - this one speaks for itself, but when we say easy, we mean easy. 
  • Fully detailed manual, excellent service and support
  • Features a wide setpoint temperature range (-30° F to 220° F) and differential adjustment (1° F to 3° F). The temperature sensor is a 1.94 inch thermistor on an 8 foot cable.

What should I set the differential to?
A shopper on Nov 6, 2014
Best Answer: The differential is how many degrees from your set (or target) temperature the controller will allow. For example, if you set a differential of 3°F, the controller will wait until the temperature is 3°F cooler or warmer than your set temperature before activating the heating/cooling unit. The controller will turn the power of your heating/cooling unit on or off as needed to maintain a temperature within the differential.

For a more precise temperature, you should set a smaller differential. However, be aware that too small of a differential can cause stress to your heating/cooling unit by constantly turning it on and off.

Can the unit be calibrated? How accurate is it (NIST traceable)? Is the differential temperature adjustable?
Ron W on May 11, 2015
Best Answer: Hi Ron,
The A419 cannot be calibrated. This unit uses the A99B sensor which has an accuracy of +/- 0.9F. It is very accurate but I could not find if it is traceable to NIST. You can set the differential anywhere from 1-30F.

Where do I put the probe?
A shopper on Nov 6, 2014
Best Answer: The probe can be applied internally or externally within the product you are trying to control. If you wish to heat/cool with the probe inside of the fermentor you will need a stopper thermowell in order to contain the probe within the liquid of your fermentor. We've found that the probe can adjust for temperature by suspending in a refrigerator/freezer for cooling or taping to the sides of the fermentor when heating with a heat wrap.

Does it heat and cool? Not just the settings, but can the unit itself heat up or cool down my beer?
A shopper on Nov 6, 2014
Best Answer: The unit is used as an external controller, in conjunction with a heating or cooling unit such as a heat wrap or refrigerator. It does not supply the heat/cold itself.

Should I set it to cut in or cut out?
A shopper on Nov 6, 2014
Best Answer: Typically, cut in is used for cooling and cut out is used for heating.

Cut in: this means the controller will activate the heating/cooling unit at the set point temperature and turn it off when the temperature falls outside the differential range (lower differential for cooling, upper differential for heating).

Cut out: the controller will activate the heating/cooling unit when the temperature is outside of the differential, and turn it off when the set point is reached.

Is there any special wiring required?
A shopper on Nov 6, 2014
Best Answer: There is no special wiring required with this controller. Just plug your heating/cooling appliance into the controller, and plug the controller into an outlet. Place the probe where you want to take temperature readings from, whether it's the room you're fermenting in or directly inside your fermentor. The controller will activate the heating/cooling unit as needed to maintain the temperature.

To switch the unit from Cooling to Heating or vice versa, two small jumper tabs are located inside the housing of the controller, as detailed in the manual.
