Using this Invensys simmerstat control for your Technika cooktop is easy. Just turn the simmerstat to adjust the heat. Remember, it won't turn continuously and stops at about 355 degrees. To activate the neutral switch, turn the simmerstat fully clockwise until you hear a click. It'll stay on at any setting until you turn off the control. When it comes to installation, note the mounting hole spacing. It's 20mm in one direction and can be adjusted from 20 - 28mm in the other. Use two bolts to mount the simmerstat with its 6mm D Shaft. For maintenance, keep the switch clean and dry. If you notice any issues, check the electrical connections.
