Product Description:

This temperature controller has one output for cooling control and another for heating control.  It can be used for applications such as beer fermentation or convert a refrigerator to kegerator. The temperature control can be programmed to vary with different time step setting. Up to 8 temperature-time steps covering 33 days can be programmed. By using both cooling and heating devices, refrigerator can be controlled at specific temperature regardless in hot summer or cold winter.
 
This controller is a plug and play controller. No wiring is needed for the heater or cooler.  Both heating and cooling control modes are simple on/off control, similar to a mechanical thermostat but with much higher precision due to adjustable hysteresis band, precision sensor and digital read out.  Anti-short function is provided for cooling to protect compressor from being turned on with high pressure Freon.
 
Unlike other similar priced two stage controllers on the market, a digital silicon band gap sensor is used rather than a cheaper NTC or PTC thermistor sensor.  The advantage is being much more reliable in moisture environment than thermistor sensor. It can be immersed over extended period of time. It also has a more uniform accuracy over an entire specified temperature range. In addition, the cable of the sensor comes with food grade silicone insulation, as compared to PVC jacket used on most sensors on the market. Silicone is safer than PVC for food application, especially when immersed in the solution that contains alcohol, because flexible PVC contains plasticizer that is easier to leach out in alcohol. Silicone will also withstand higher temperature.

Note:

 

  • The controller can display temperature unit in Celsius or Fahrenheit.
  • Unlike PID controllesr we sell, this on/off controller will not hold temperature as tight if the system had very slow and delayed response. Some temperature overshoot is normal.
  • Either heating or cooling device is limited to 10 Amps. The output voltage is same as input voltage.  When the controller is plugged into 120V AC, the output will be 120VAC. If the controller is connected to 240 VAC, the output will be 240VAC also.
  • The input power plug is a US NEMA 5-15P plug. The output sock will accept US, Australia, or European continental plug (CEE7/7). Optional input & output travel plug adapters are offered. Please check here for more details.
