Triac Voltage Control
A triac-fired control replaces the usual rheostat
temperature control for each surface element. The
control receives feedback from the temperature
sensor to allow for precise control of the heating
element power.
Digital Control System
The control system consists of four circuit boards:
the touch board (which is permanently adhered to
the ceramic glass panel) that senses the user
input, the display board that contains the panel
displays, the logic board that contains the micro-
processor, and the power board that does the
power switching and control of the heating units.
