• Ease of use and reliability are the major considerations in the development of our controllers
• A clear key arrangement facilitates programming of the controller
• All times and temperatures can quickly be read on the large-sized, high-contrast display
• A number of different individual firing profiles can be saved (depending on the model)
• LEDs clearly display each program segment
• Important information such as power consumption, operating time, and error messages can easily be called up via the Info key
