2)  Connecting and operating the controller   

 

Fig 3. Typical connection between the controller and the heating device (in this example, 
the cooker).   
The connection of controller should be done in the following steps.   

  Plug the temperature sensor to the back of the controller.   

  Plug the power cord to the back of the controller and the other end to the power 

outlet on the wall.   

  Turn on the controller to make sure the controller powers up properly. The 

temperature display is in the range expected. Then, turn off the controller. 

  Plug the heater to the back of the controller. If the heater has a switch, put it in the
