Introducing the Uni-Stat IIa Temperature Controller! This is a temperature controller made for use with both hot and cold temperature devices. It has the ability to shut off the temperature device when either a high or low set point is reached, and is accurate to within 1° of the set temperature! Use this in conjunction with heating pads, heating elements, refrigerators, air conditioners...you name it! It has found popular use for fermentation control and to control cellar temperatures for wine storage.

The set temperature can be set anywhere from 10 to 220 F, with a bandwith differential of +/- 1 F. The 50% duty cycle setting allows for the unit to cycle on and off every 10 minutes in cool mode (every 5 minutes in heat mode) to avoid excessive cycling and helps to hit target temperatures without overshooting. This unit has a temperature sensor probe that can be used with a 1/4 in. thermowell sensor.

Operation is a breeze! Once everything is hooked up, simply set to cool or heat, and the device will raise or lower the temperature to the set point. No crazy progamming or insane wiring, just set and forget! Get a handle on your temperatures using the Uni-Stat IIa temperature controller!
